I have a 2012 Trek Cronus CX bike that I want to use as a gravel bike. Currently has Easton Circuit rims with 32mm Clement tires. I have a set of Hunt 4 Season wheels on the way, and I’d like to mount Panaracer Gravel Kings, ideally 38mm. Anybody know if these will fit the Cronus? Thanks.
Just measure it. You’ll need at least 3mm more space on each side. The tyre shape might change that slightly, but tbh if it looks like there’d be less than 5mm clearance in any place, I wouldn’t run those tyres anyway.
I’m just finishing building a Cronus CX as a gravel bike and I’ve comfortably fit 38mm Specialized Pathfinder Pro tires. Go for it!
Hi there, sorry to piggy back on your thread. Where did you end up with tyre sizes? I’ve got the same build with a Cronus ultimate I’m converting to a gravel bike. Did you try 700 X 40 tyres?
I went with a 38mm Gravel King SK. Worked fine. Unfortunately my SRAM rear mech snapped in half and broke the hanger, so the bike was unusable. I really liked that little bike. Worked well for central Texas gravel
Thanks very much for the reply, yeah mine has suffered the same fate but the frame just about survived. Mech hanger is on with one bolt! Happy riding!
Cheers
Mat
It’d probably take 35rear / 38front with most tires before you start losing paint if it’s anything like my old Trek Crockett
My wife has a 50cm Cronus CX and it took 40mm Maxis Ravager tires (albeit on older/narrower Shimano rims) without problem. Probably wouldn’t work with a modern 25mm rim - I’d guess 36 or 38mm would be the max with the wide rim.
