Can I run 40c WTb tires on 19.3mm (Sun ME14A) rims?(5 posts)

Can I run 40c WTb tires on 19.3mm (Sun ME14A) rims?Colin_S

Hi,

I need to choose which rims to run on the bike I'm building. Anyway, I have a set of 40c WTBs left over and would like to be able to run them -- if they fit. Will I need wider rims to run the larger cx tires?

Thanks,
Colin S.

most likely. WTB makes a rim for the 2-9er MTB's that will work. So will the Salsa cross rims. Do you have enough fork and chainstay clearance? I'm running 38's on Open Pro's without any trouble

As far as clearance, I'm not sure yet. I haven't decided for sure, but I'll probably be getting a Planet X Kaffenback. I have a set of Terrainasauruses left over from an ill-fitting Surly that turned me off to road riding. haven't had it for almost a year now and think I might want to take another stab at a 'cross/road bike.

I run 38c Tioga BloodHounds on my Campagnolo 13c rims at 80psi, so I can't see why you'd have a problem. I admit it's probably not the best set-up but it works fine.

Odd topic title, but nonetheless..

I have a Kaffenback frame that I haven't built up yet, but I did try some tires, and you'll definitely need to replace the stock fork if you want to run those Terrainasauruses. A 32mm Ritchey SpeedMax *just* fit in the fork, with absolutely no clearance for mud or anything else for that matter. Planet-X only claims clearance for up to 38c tires in the back, but I haven't anything that large to try out, but it sounds like yoru tires would be tight in the back if they would fit at all.

Planet-X isn't really positioning it as a CX bike, but it'd be nice if they let people know on their website that they'd need a new fork if they want to match what they can fit in the rear.

Paint is very soft too - many chips just from storage.
