A 105 can usually handle a 30-tooth cog, but 32 is pushing your luck. Like others have said, you need to put a proper MTB derailer on to eliminate the 105 as the culprit, then see if there's still a shifting problem. And yes, 9-speed derailers are fine friction-shifting 8-speed cassetes. Joe Bernard Vallejo, CA. On Sunday, July 8, 2012 12:36:23 PM UTC-7, Steve Palincsar wrote:
