I believe the Sphinx will handle a 700 x 46 no problem. Also have some 650b rims I could put on either bike with some modifications to the brakes
Looking for opinions on which one you would convert to a Gravel bike and why? Thanks for any additional information.
So has anyone even owned the Gary Fisher Sphinx? It is very hard to find much information on the bike. I mounted some Specialized 2.1 inch Ground Control tires, and the front is fine but the back is tight in the chain stays also rubbing the front derailleur hanger bolt. I am guessing I think max width might be about 1.95 inches or about 49mm?
