apologies in advance: another tire thread

[azrider]

Sorry. But seeking knowledge in area I'm not too familiar with and my "searches" have resulted in MORE questions so please bear with me....

Got myself a 'legit' crossbike. I say legit because prior cx contraption was a Specialized Tricross from 1999 which was neither gravel bike or CX.....but it could fit fatty 700x43 tires.

I "saw the light" with regard to fat tires and sold the Tricross and got myself rim brake Crockett.(yay) The guy that sold it to me said I wouldn't be able to fit anything bigger than 700x38 cause it was "true cx 'race'" bike (uhhhh okaaayy) so I'm in market for 700x38 tire that is super durable and will see 50% hard-packed dirt (canal), 30% rough road, and 20% gravel.

This will also be my go to winter and commuting bike so I'm leaning more towards durability than performance.

Lastly....what about tubeless? The Tricross had tubless 700x43 Gravelkings and holy cow it was so supple and nice at 50 PSI......especially when commuting with 15 lb backpack. Will I lose some of that suppleness if I go with a tire that requires inter tube?

Sorry for being annoying and asking YET another tire question.

Shutting up now.

DAMN that's cheap too!! So regarding tubeless.......I live in AZ and my garage is literal kryptonite to stans. Will running thorn resistant tubes decrease ride quality dramatically? Normal tubes?

[HTupolev]

Yes.

Normal tubes?
Not to a huge degree in and of itself. If it causes you to run higher pressures than you'd otherwise prefer in order to avoid pinch flats, then yes.

What rims are on the Crockett? Who set up your 43 GK's tubeless? The 38s are pretty much the same. IIRC canal riding in the PHX metro is a lot of goatheads. I'd roll tubeless if at all possible.

almost forgot my tire recommendation! for the surfaces you describe, I would check out the Donnelly X'Plor MSO, 36mm wide, set up tubeless. I've had incredible luck with their tires set up tubeless, even at super low pressures in CX practice and riding singletrack. not using Stans though; Orange Seal. as long as you've got tubeless compatible rims, shouldn't be a problem.

[HTupolev]

Yep. CX is specifically an underbiking discipline; people aren't riding road-esque bikes with skinny tires because it makes sense, they're doing it because that's what the sport is. On some cyclocross courses, going considerably wider could allow better performance, but they stay skinny because skinny tires are what UCI Cyclocross is.

Some governing bodies don't really care, though. At entry-level USAC stuff, you see people riding pretty much every kind of bike imaginable.

[jtbadge]

You should be able to fit the 43c GravelKing in your Crockett. I've seen them with 43c Bruce Gordons before - even the older canti version.

UPDATE:

Found this one (https://www.pedalroom.com/bike/trek-crockett-35905) with 43c GravelKings.

My understanding is that unless you're riding in a UCI event or the national championships, USA Cycling does not enforce the 33mm tire width rule.

Wow very cool. Lots of good info here. Thanks for sharing. Good to know on the UCI stuff....that HAS to be what he meant cause I am currently running 34's and there is GOBS of room.....

Bontrager race?? I’m assuming they’re what came on it

Look at the offerings from WTB. I believe they have a 700x38 with some bite, almost all their tires are TCS (tubeless). I have also been very impressed with every tire from Specialized that I have used. I believe they have a light traction 700x38 CX/gravel oriented tire also. And some friends of mine who had choices of tire sponsors went with Maxxis and are running 700x35/38 offerings on their racier cross bikes. Usually for long gravel rides with pavement in between. Tire options are a bit overwhelming these days.

I'm almost positive those are tubeless ready. I think that's the icon in gray on the R side of the label.

If they are like every other bontrager rim I've tried, tubeless should be pretty straightforward with tubeless ready tires. Tape, valves, soapy water, air compressor, sealant, ride.

I have the same pink frame, nanos (40) fit with room to spare. Limit is the drive side chainstay. I have compass Steilacoom 38s now and they have lots of space.

Got a wheel set with 38mm simworks slicks and they are great, basically the gravelking but with more sidewall protection.

Hey thanks for info!!!

Do you by chance have link that could direct me to the "slicks" you speak of ? My searches are coming up with multiple sim slicks.......thanks.

[Bentley]

I have the same bike with 42 Clements (I know they changed the name) but I could go wider. Obviously, I have to open up the brakes to get them in but not sure why you were told they only fit 38’s.

Look at the offerings from WTB.

It's funny, I've been reading lots of "What Tire Should I Use?" threads recently because I figure I'll need to replace the tires that came on the CAADX I got this year...which are WTB Riddlers, 37c. Meanwhile, I've got a couple thousand miles on them already and they show no signs of wear or needing replacement any time soon, and I have yet to take them on a surface where they didn't seem perfectly adequate: hard-pack, loose gravel, gnarly singletrack, pavement, etc.

Perhaps my next set of tires will be another pair of WTB Riddlers?

[bigbill]

I've ridden all over Ft McDowell on canal roads, dirt roads, and the Pemberton Trail on 35mm Gravel Kings. I think 38's might be better but that's what I was riding earlier this year. Set up tubeless and I picked up a few goatheads but didn't give me a flat. I'm currently using Stan's but as soon as that runs out, I'm switching to Orange Seal. Not many people around here have good things to say about Stan's in this environment.

Perfect thanks! And you say these are fairly durable eh?

My Bontrager CX0's that came with bike finally gave up ghost. Unfortunately it happened Friday night and I was desperate to take "that" particular bike on group ride. So quick trip to Performance and I got some Gotham ST 700x35 "all arounder" tires.............HOLY CRAP what a mistake. I kinda sorta felt like I knew what I was getting into but thought running them at 50-60 would help with the "ride"..........boy was I wrong.

To add insult to injury I opted for some "thornless tubes" and it's one of the harshest setups I've ever ridden.

Guess I'm back to either Gravelkings or these Sim Works.
