Rear Shock Reducer Maintenance
It's tradeshow season-Eurobike just concluded and Interbike is up next. Delays and longer response time can be normal when people are out of the office.I got mine for the first gen tallboy. says they are 8mm and mounting width of .860. having a hell of a time getting the inner du bushing out to install these and just want to make sure i have absolutely the right size. i also cracked the carbon upper link and have had a hell of a time getting a hold of santa cruz the past two weeks to get a warranty replacement.
