1hill@aTime Posted August 28, 2007 Posted August 28, 2007 hi all hubbers.. i would just like to know what needs to be changed to make my bike a 10sp, i know the cassette, would the rear derailer also have to be changed?
1hill@aTime Posted August 28, 2007 Author Posted August 28, 2007 ok so not such an easy things...thanx, 9sp it will be for awhile
Mudsimus Posted August 28, 2007 Posted August 28, 2007 Rear deraileur' date=' cassette and STi's...[/quote'] chain
linnega Posted August 28, 2007 Posted August 28, 2007 Yes - cassette, rear derailleur, levers and chain.
NotSoBigBen Posted August 28, 2007 Posted August 28, 2007 Why the rear derailleur guys? Surely the movement it makes is the same for all cassettes and the high and low adjustments are the same as you pretty much have the same 'width' cluster but with 1 extra gear? Also the biggest and smallest gear on the cluster is still the same size? The STI's will make sure it 'only' moves the necessary amount to change for 10sp (fractions less than for 9sp?). I would go with cassette, STI's and chain. In fact will be doing exactly that on Little Ben's bike soon and we'll see!
scotty Posted August 28, 2007 Posted August 28, 2007 I know the 9spd derailer works on 8 spd, but dunno so much about the other way.
1hill@aTime Posted August 28, 2007 Author Posted August 28, 2007 Bigben once you have done please let me know if it works, it does sound logical, the range of movement will be the same.
NotSoBigBen Posted August 28, 2007 Posted August 28, 2007 Sure! Just waiting for the left STI to arrive (long story!) and we'll test. Have the cassette and chain already! BTW - we are using an old 8sp 105 RD on 9sp TT shifters on my son's TT bike and it works fine, hence my logic!
sias Posted August 28, 2007 Posted August 28, 2007 I think the old deraileurs could still be configured to change both the 8 and 9 speed cassettes, but I don't think they can be made to shift 10 clicks even though the casette width is the same. Let us know what happens...
IanC Posted August 28, 2007 Posted August 28, 2007 Scotty isn't the rear derailer I got from you a 10 spd derailer? I'm using it on 9spd and it work fine.
NotSoBigBen Posted August 28, 2007 Posted August 28, 2007 Ok well that sorts that then! Saves a few bucks.(of course if Scotty says yes)
scotty Posted August 28, 2007 Posted August 28, 2007 Correct IanC, my mate went one better and fitted his to 8spd Sorra and it works BB you have my approval to proceed
NotSoBigBen Posted August 28, 2007 Posted August 28, 2007 Done! Gonna cost me just a left hand ten speed STI lever (Dura Ace). Anyone got one 'lying' around'?
