Starting a 650b build

[A1CKot]

Taking advantage of the holiday deal I ordered up the essentials to convert a old Trek 5200 frame into a 650b commuter. Wheels will be Miche Racing Box 28 hole hubs laced to Pacenti SL23 rims with DT Comp spokes. All in silver! I picked up a pair of Compass Loup Loup Pass 38 tires with tan sidewalls to try and squeeze between the chain stays. The chain stays are going to be tight but hopefully it will work

The frame is painted this purplish color that I'm removing to reveal Trek wonderful carbon work. I may go with a simple graphic or leave it blank. For the build I'm leaning toward a flat bar set up with down tube shifters... Should be cool! What do you think?

[scrubadub]

Sounds like a fun project. It seems like a couple of us have been gravitating toward Trek OCLV frames and downtube shifters. I'll be curious to see if those tires work.

[weisan]

A1 pal, good luck with the conversion, it's gonna be fun. I enjoyed converting an old steel bianchi two years ago and turned it into my daily driver. So far, it's been great. I even used it regularly during the week to do a lunch ride on the trails, it has held up well especially with the fatter tires.

Two things I can say about 650b conversion is, tires and brakes.

The tire choice is important based on where and how you gonna use the bike. I love the one I am using, Panaracer Col de la Vie 650B x 38mm - cheap and adaptable to the different terrains.

Brakes - obviously, this is a key component of the conversion, getting the right clearance and reach. I found this very useful:

Good luck!

[marciero]

Agree that tires and brakes are key. Tires are the sole reason for doing a conversion in the first place. You will love the Compass. For commuting you may want something more durable, or not.
Brakes are the big compromise on 650b conversions. The long reach brakes do not work nearly as well. BUT, for commuting on flat-ish terrain they will be fine.

Why are Treks suitable/desirable for 650b conversions?

This same article planted the seed in my head. Measured up the frame and it should work with Tektro R559 55-73mm brakes that I also ordered. worst comes to worst I have all the parts to try and covert some other frame if this doesn't work.

Do 3 cross rear lacing...:D

2 cross front and non drive. 3 cross drive.

Why are Treks suitable/desirable for 650b conversions?

I don't think they are suitable/desirable for 650b conversion. I haven't seen one so I thought this would be a good topic to start. I think scrubadub's comment was due to the number of WTBs for LA era Trek carbon frames. They were and still are good frames and the prices are almost to hard to pass up. Mine is an older one with a King threaded headset that I picked up for $220 shipped to my APO. I originally picked it up to repurpose some parts into a single speeder but 650b with wide tires a rack and maybe even fenders seemed too good not to try. My 5200 had threaded holes in the rear dropouts that are perfect for a rack that I have on hand.

I'll post some pictures this weekend with the progress I've made removing the paint and when ever parts start to arrive. Should be fun!

[scrubadub]

My interest in the Treks as a project bike is that they are plentiful and usually have downtube stops for shifter mounting.

Looking forward to the build!

[Pastashop]

If you're going with downtube shifters and a flat bar, consider these:

http://www.jitensha.com/eng/flatbar05.html

really wonderful bars for city riding and general toodling around. i installed them on one bike and they're great. (some people even use them on their randonneuring bikes)

Got it. Thanks for the clarifications

Ok, I read the article. I am in. My Salsa Caseroll might be perfect. My Serotta Concours might be perfect.
I have a set of the long reach Tektros 556.

Anyone know where I can find a 650b wheel set for a reasonable price?

[weisan]

good for you, legend pal!

You can try these places:

velomine
bikewagon

The last time I looked, they have some really nice cheap 650b wheelset.

'Reasonable'? I can build you one, 6800 hubs, Velocity A23 650b rims, Sapim spokes, 32h/3cross/brass..for about $375 shipped.

This will be 10 speed. In fact, I don't even have any 11 speed bikes (I never thought I would be a Luddite). Can I use my 10 speed cassette on the 6800 hub?

I like the OCLV frames. A Trek 5200 converted to a fat tire townie? That's so wrong that it has to be right!

Looking forward to seeing the results.

[MerckxMad]

Have you measured the fork clearance? I'm trying to picture a 38 wide 559 tire fitting in there.

[weisan]

Thanks.

I like the Panaracer Col De La Vie, as a cheap, good, all-around general purpose tire adaptable to varied terrain -pavement, trails, gravel.

[palincss]

How about tires? What do you suggest?

Odds are you aren't going to be able to get 42mm tires onto a 650B conversion. Generally, the widest you can do is a 38mm tire. There are several nice tires in that size, and your choice will depend on intended use and budget. If you're looking for a road (paved & gravel) tire and have deep pockets, I don't think you'll find anything better than the Compass Loup Loup Pass with the EL casing https://www.compasscycle.com/shop/components/tires/650b/compass-650bx38-loup-loup-pass/ but they are $78 each.

Some 650B conversions (I recall seeing a Bridgestone RB-1 that had been converted that's a fine example) won't fit wider than maybe 32mm. The best choices there would be the Grand Bois Cypres or the Hutchinson 650B x 32 Confrérie. The Cypres 32mm standard casing & the Hutchinson are $57; the Cypres 32mm is available with an EL casing for $76.

[weisan]

I second Palincss pal's comment...esp. if you are gonna use OCLV for conversion.

[RFC]

First, let me emphasize that I fervently support all sorts of Frankenbike nonsense and revel in it myself. Therefore I strongly encourage you to carry on with your LA OCLV big tire upright townie.

That being said, in general (I get the OCLV aesthetic) what is the advantage of converting a 700 road bike to 650 other than to just make fat tires fit? Why not just get a classic 700 frame already designed for fat tires, like these? I still have the Litespeed and the Cannondale, both wearing 37mm tires.

Why are Treks suitable/desirable for 650b conversions?

The CF Treks really aren't that sought after for 650B conversions. The late 70s/early 80s Treks are desirable for their geometry, affordability, quality and tire clearance.

Thank you. 32-38 is hopefully sufficient. I believe my Salsa Casseroll can take pretty wide tires, but too wide may not serve my purpose.

Palincss is right. Reading this thread, it occurred to me that I have a quite old 56cm Trek 5200 with matte gray finish, threaded headset and the rear dropouts with fender/rack mount holes. Testing revealed a 650B-38 Loup-Loup Pass fits in the front with a few mm to spare. In the rear, it rubs both chainstays. A 32mm tire should give you about 3mm on each side, which is doable although less than I like. Still it should be a fun project even with 32mm tires.

[Pastashop]

My $0.02 that you probably don't need: I'd keep the tire pressure in check -- I tended to pump them up at 38x650b just a bit lower than my 28x700c (like, 70 psi vs. 90 psi), and the ride was harsher than I was looking for, perhaps because of the smaller overall wheel+tire diameter and rim/wheel stiffness. Dropping to 50-55 felt better. With a stiff carbon frame, the higher frequency vibrations (e.g. on chip-seal) will be in check, but unweigh for the big bumps!

Well, sure. I'm over 200 lb and I run my 650Bx38 tires at 50 psi. 70 is much too much pressure. If you're running 28mm at 90, then you'll be fine with 32mm at 70. Of course, no matter what you are riding you should always unweight for the big bumps.

For sure. When you can. Sometimes I get tired :-)

Also. There are some nice dirt roads around here that most folks ride on 700x35 mm or fatter tires. I used 700x(25-28) at 80-100 psi, but had the luxury of nice steel frames with reasonable wheelbases. Problems occurred in group rides, when I couldn't see ahead to the potholes, while the lead would miss calling it out. So I got me a 650x38 steel rig for those group rides, although I've been enjoying it just the same on solo sorties.

Thinking of trying Hetres, but would have to take off the fenders for clearance, and don't feel like doing that this time of year.

OH NO!!! Thanks for the heads up. I may still be able to change my order before it ships. I measured the best I could and it looked fine everywhere except the chain stays. Good info and I'm glad I started this thread.

So I'm using a old Trek carbon road frame because I picked it up cheap with the intention of using it as a cool low(er) cost 700c single speed build. Building it geared with 650b wheels isn't going to cost me all that much more than I had planned so yeah. Fun project that I haven't seen.

Also I'm now thinking about using bullhorn bars just for fun!

So which tire would you suggest for fast road riding? I did so few road rides this past year because our roads are so bad and my wrists have suffered. I ride my fat bike half the time on the road just because it eats up every road imperfection.

I think my Casseroll will take 38mm tires, but 32mm might be the limit.

Then you definitely want the Compass or Grand Bois with the EL casing, in whichever is the appropriate width. It's actually pretty surprising what a great job the EL casings do on rough roads. In my estimation, definitely worth the price difference, especially if you're sensitive to harshness and vibration.

Sounds like the Grand Bois with EL casing is the ticket for me.

Thank you.

[A1CKot]

A small update while I wait on parts. So I was able to swap my order over to Grand Bois Cypres 650B x 32 so I should be good based on roydyates test fit with he 38s. Also I started striping the frame to reveal Trek's carbon work.

The tubing junctions are going to be the most difficult part.

So my hubs and spoke made their way through the busy post office yesterday and I couldn't resist lacing them up. This is the first wheel set I've built from new. When I was in high school I took apart and rebuilt a pair a wheel a few of times just to learn. I made a couple of lacing mistakes that I only spotted once I started to tension everything but other than that it went smooth and only took most of the afternoon.

I added a picture of what I have for the build mocked up. I still have a lot of paint to remove and a bunch of parts to locate but its starting to look like a complete bike!

[oddsaabs]

Congratulations on finishing your first pair of wheels! Very rewarding process.

It's not a big deal, but if you look closely at the lacing pattern you'll see you've got the valve hole off by a 2 spokes. It should be between 2 "parallel" spokes, instead you've got it between 2 crossed spokes. This won't affect the performance in any way, just the aesthetics and the ease of getting a pump head on the valve.

Again, nice work. It is very rewarding riding wheels you built yourself.

Congratulations on finishing your first pair of wheels! Very rewarding process.

It's not a big deal, but if you look closely at the lacing pattern you'll see you've got the valve hole off by a 2 spokes.

Thanks. I see what you are saying. I started with the front wheel and googled 2x lacing pattern and didn't really find what I was looking for. So I copied a wheel I already have and didn't even think about the valve stem location. I started in the same orientation for the rear so at least they match. No problem fitting the pump but a mistake to learn from for sure.

Now I need to figure out what handle bars and stem to use... I can use a longer stem and flat bars or a shorter stem and bullhorn bars.

Please tell me this is getting downtubes.

I've got a 130 and 140mm quill stem if you go flat bar.

You know it! I found a pair on eBay after I finished the wheels. So the shifters are on the way but I still need to figure out a crankset and brake levers. I would love a White VBC and some Paul Love levers but this is a budget minded build that will spend some time locked outside. So I think I might need to get a little hands on to get/make some silver parts.

Pm me the stem details. The 140 should put the bars about even with where my hoods start on my primary road bike so that should work for flat bars.

Gent that taught me wheelbuilding taught me to build 32h with the spokes 'crossed' at seam and valve, cuz that was the weakest part of the rim. Did it a few times but customers gave that 'thousand yard stare' when they got them.

Also, there is a MO outfit in the republic that used to say 36h were 'weaker' than 32h cuz fewer sections of parallel spokes on 32h...silliness abounds.

Methinks cuz they couldn't get 36h stuff...just an aside.:D

Nice hubs/rims, etc...good for you Airman!!

Congrats on building your first set of wheels, I really dig them. I do all my own mech work with the exception of building wheels. For some reason it seems really intimidating. It is always cool to see another take this on for the first time and nudges me a little closer to trying it myself.

[thirdgenbird]

Ok sent on stem.

If my vote means anything, crankset:

Re-labeled Sugino, don't know about the finish on the Stronglight's but a similar designed 110 BCD Sugino should be less expensive.

I thought so too, but I haven't found the Sugino for less than $100

Thanks OP. If anyone brings it up I will use the "I crossed over the stem and seam for extra strength." Hopefully they won't notice the 2 cross front and rear non drive side.;) Not a big deal though. Part of the learning experience.

Rada- I have a trusted LBS back in Illinois that I usually take wheel builds to but the logistics of shipping (APO costs extra) everything twice outweighed the benefits of just buying the correct tools and going for it. I was able to score an awesome deal on the new powder coated TS-2.2 truing stand with the base, dish tool, and the tension meter over the Thanksgiving weekend. Such a good deal that I could recoup my cost if I ever wanted to. In the end I found it rather calming and very rewarding. Going from a pile of parts to a ready to roll wheel set in one afternoon felt like quite an accomplishment.

I have had my eye on this crank for some time. Not sure though. If I haven't found anything by the next Ribble 10% off sale I might go with it.

Would love to hear your impressions! I'm thinking of using those for my 650b light wheel project.

Will post when I can change my brakes, install these and get a ride in...probably not till Tuesday. They seem pretty supple.

I ordered some pari moto's when these appeared to be lost...waiting on them.

I looked at the CDLV's, but 500g per tire for road riding isn't what I was looking for.

I got a flat on my first ride :crap::crap::crap:...I haven't had a flat on the road since 2012.

I set the psi at 55/50 and my Conti Sport 700 x 28c's at minimum psi are plusher and more forgiving. Will have to try at 50/45 psi.

They felt fast, fwiw.

[TT Tandem]

Late to this thread but!!!
I am in the process of a conversion build. Using my 1983 Schwinn Super le Tour. I have re-finished the frame, waiting for my spokes to build up the wheels and getting the other bits and pieces together.
I am planning to use Mustache Bars as I have always wanted to give them a try.

[kobetsang]

I converted my 1987 Waterford built touring paramount to 650b last year. The change is massive. I could fit 28c with fenders before. Now I've got 41's in there with the same fenders. You can see pics on my Instagram (https://www.instagram.com/gideontsang/).

Hmm... Interesting. In my rides on 38mm wide Lierres, 50 lbs feels noticeably harsher than 45 lbs, but is measurably faster even on (somewhat packed) dirt roads. Trade-offs...

Speaking of trade-offs, the 700c size is probably no accident, as it seems to optimize between a lot of different parameters: the smoothness advantage of larger diameter wheels, the lower rolling resistance of higher pressure tires, the strength of a rim against excessive inflation force, and the lower weight of a narrower (but not too large diameter) rim.

The only advantage of 650b over 700c that I see derives from wanting to carry stuff on a bike, running fenders, and encountering rough patches over a loooong ride. Well, and keeping with the whole "safety bicycle" notion, especially for folks shorter than 5'9"...

The design thinking in my mind, given this application, goes like this: Carrying weight on the front wheel is better with respect to longevity of the rear wheel, which is dished and less robust than the front wheel. To carry weight on the front wheel without adversely affecting handling, less wheel flop and "quicker" turning is desirable (achieved with steeper HT angle and less trail). The caveat on the HT angle is basically that it's derived from the vector of impact from a pothole in the road most often to be encountered, softened a bit by a fatter tire that can absorb a larger deflection before "bottoming out". Working with these constraints, we wind up with essentially a road bike style geometry of the frame and fork, but need a fatter tire while keeping the outermost diameter to less than 700x23 to keep nimble steering and to fit fenders without severe toe overlap.

Incidentally, randonneuring, porteur and city bike applications have very similar design requirements, and so we wind up with 650b x 38-42mm tire sizing.

I reckon also that one could have their cake and eat it with respect to speed and comfort by going to longer wheelbases and skinnier steerer tubes. The double triangle of the frame has negligible vertical compliance (unless you're talking about a Castellano design or a Slingshot), so perching between very spaced out wheels is one way to go. And since a typical fork flexes mostly inside the head tube, a skinny one can help absorb road shock. (Problem is that these parameters are likely to encourage shimmy / bifurcation, so, that's another constraint.).

Whew... That's TLDR right there to basically state the obvious.

On balance, I'm mostly amazed by the fact that it's awfully difficult to improve upon a 100 year old design that's been in continuous and widespread use and iteration for most of those 100 years.

[93legendti]

Every tire pumped too high gives me a harsher ride than I prefer. I have no doubt that once I find the sweet spot, the ride will be very cushy. My Bike Friday Pocket Rocket and Pocket Rocket Pro have 20 X 1 tries and ride very smoothly on the same roads, as long as I have the psi set where I like it. Even my BF Tikit with 16" tires rode very smoothly.
