Hi,
I ride a 2007 Cannondale Rush and have done quite a few mods and upgrades. I am now finding that I have damaged the large chainring a few times and considering how little I use the large ring on the trails am considering removing it, increasing the size of my middle ring from a 32t to a 36t o 38t (granny is a 22t) and installing a Cycle Logic chainguide with bashring, BB mount, adjustable for 36-38t chainring with an MRP roller. My current ringset is Truvativ Trushift and I am thinking of buying the Blackspire Superpro Middle Ramped 36t. Does anyone see any reason why I shouldn't do this and any issues I might face with the upgrade to a bigger middle ring without changing the granny ring size? Also is there anything I need to do to compensate for the missing large ring? Cheers
