I'm looking at changing my worn sprockets (916bp), the rear is 38T and i notice that the standard size is 36T, my chain when loosened to its max on the cam wont clear the sprocket, and the hub wont pull off due to lack of chain clearance - i'm probably going to have to use a chain breaker and refit a new link...what advantage would there be by using a 38T over a 36T? Also looking at fitting a quick release carrier, any recommendations?
DO NOT go back to a 36... Trust me. The bike handles like Shit on a 36. Massively over-geared. You'll be hunting between 1st and 2nd at any speed less than 50mph. Changing to a 38 (which I did September last year was the BEST decision. Most 916 / 996 riders go for 1 tooth down on the front sprocket which is about 3 up on the back - But 2 on the back has been revolutionary... IMO Just hit the sweet spot on drivability, accel / cruising etc
Renthal QC carriers and sprockets used to be the go to items for a while but the sprockets dont last that long, even with diligent maintenance. Supersprox are a good alternative, as they have a hardened outer (toothed ring) and an alloy hub so you save a little on unsprung weight. They can be married to a number of QC carriers such as CNC Racing, MotoCorse or AEM, to name but a few.
..... Definitely ! It's by far the better option ...... -1 on the front sprocket puts more wear on the chain * ..... and also on the front sprocket itself . And it doesn't feel nearly as smooth , even though the final ratio is roughly the same as +2 on the rear . * about 7% more chain wear ! It's all down to the maffs , innit ...... ....as such .....
There is plenty of choice for QD carriers. RK, Supersprox, JT all do them with steel sprocket options. I believe the renthal only offers an alloy sprocket, which will wear faster. The QD carrier makes life easier moving forwards in that sprockets can be changed without taking the hub out, but how often do you change sprockets ? Once in a bikes ownership maybe ... Is that worthwhile .. ?
I think the main reason for changing to a Q/R sprocket carrier is to get one with the flanges at the rear to prevent the Cush drives from backing out and wearing the rear hub adjuster.
