I've got a 2011 jamis xcr team 26r with a shimano xtr m985 2x10 drive train. I'm really struggling with the lack of a granny gear for tough technical climbs. The stock gearing is 28/40 on the front and 11-36 on the back. I have not been able to find any options for switching out gears except to go even taller. As far as I can tell ( but consider I don't know much!) is that I need to switch to a triple in the front as well as a new front derailer. This seems like a lot of dough just to switch my gearing. Does anyone have any thoughts or other options?
