650B wheels for gravel - options!

[Clancy]

Will be picking up a Norco Search XR steel frameset at the end of the week. Plan on building it up using 650B wheels. Only problem, I know very little about the options out there.

What are my choices? Prefer center lock but not a deal breaker.

What inner width should I look for?

If I build some up with DT Swiss 350 hubs, what are my choices for rims?

Quite a few DTSwiss rims for 650b(27.5)

Altho availability might be spotty.

This one too. Really nice rim

Your thoughts on the DT Swiss XR 331?

I found the 361 on the DT Swiss site, but seems to be limited availability.

For reference, I weigh 155 lbs kitted up and ready to ride. I don’t see running anything wider than a 47c, on the 650B’s, probably a 35-38c from Panaracer or Compass.

Never seen or built one in the wild but like the R411, light rim. I can get you either..DT350 hubs as well or buy some and send them to me. XR331 and XR 361 both about $90...I like the 361 more better, PLUS rear OC..as it's a bit heavier(50 grams or so) and for smashing around n the dirt, not a bad thing.

Maybe 331 front and 361 rear? Altho they come with alloy Squorx, I'd build at least the front with brass.

My 28spoke 331 650b wheelset currently has a 2.1 on it and does the job fine. 135 lbs.

I also wonder why people say its much more fun with 650b's.....

[bigbill]

I'm pretty sure I can run a 650 with a 47mm tire on the Coconino. The idea is a bigger tire that will still clear the frame. For now, I've got a 1.9" MTB tire on the front because the fork has ridiculous clearance. I've got a 38 on the back. It works for me.

Build your own!

Accepts up to 2" tire.

People say it's more fun because of the tires and where you can ride.

700c/29x28mm tires is about the same size as 650b/27.5x47mm, so you'll still have the same bike geometry just 19mm more tire so loads more traction. Also you can reduce the pressure a bunch, which also helps with traction and comfort when off road. Top speed on tarmac will be lower with the smaller wheels.

As for rims, anything below 450g or so should be fine in terms of spin-up feel so there's plenty of options no matter the budget. The XR361 looks like a great combo as well, especially like the asymmetric spoke hole pattern which allows all the spokes to be the same length and evens tension a bunch.

yeah there is nothing more fun than a 2.1 650b tire on a road bike...

I bet the 54mm 26" tire is also super fun though.

Awesome!!! Thanks for the explanation... will look into trying out those 650b's

ebauman has a set of new XTR 27.5 wheels, if the TA options work for the frame, these would work well for your needs, and at $350 for a ~$1,500 wheel, they are dirt cheap.

Here is the link, says sold, but his last post says he has another pair. May still be available.

Those wheels are an insane deal with a few caveats;
-The ID is a rather narrow 20mm. As long as you don't intend going much wider than a 2" tire the ID should be enough.
-XTR hubs have no ability to switch axle standards, so you're basically stuck with the sizing you get unless the dropouts of your frame and fork are designed to play well with the various slip-in adapters.
-The cost of a replacement rim WILL be more than the cost of a new wheelset in case you ever damage one. This shouldn't be a problem as the carbon/alloy Shimano rims have proven to be nigh indestructible

But if the above aren't important issues then there's probably no better bang per buck than those XTRs for 650B/27.5.

I have DT XR331s laced with White Industries CLD rear and Shutter Precision front on my Chapman. I really love these wheels, and the rims feel much more confidence inspiring than my Enve rims did. Granted, one of the Enve rims bowed mysteriously on the side of the rim, hence the switch to the DTs. The wheels with the DT rims are a bit lighter. Noticeable on a scale, but not sure I notice the weight difference on the road. The 361s also seem nice given the asymmetrical option. I like OldPotato's idea of using one of those in the rear and a 331 in the front.
