I'm currently building up a cross bike for next season and I've got a question with my 1x10 setup.. I'm looking to use an ultegra 6500 crank (9 speed 39t ring) while running sram rival 10 speed shifters, cassette and rd. Why? Because that crank is in the parts bin and I'm hoping to save a few bucks and not have to purchase a new chainring
I'm just wondering how big of a problem will the bigger chinrings on the crankset be since I'll be using a 10speed chain.. I'm thinking it'll be ok since I'll be running it as a single up front (with bashguard) and wont have to worry about shifting compatibility with a front mech.. Or should I just stop being stingy and pick up a 10speed chainring?
Any help would be great, Thanks.
