Please Lord, not a 10spd MTB group. 9spd can only just cope with the gunk and 8spd was the optimum in my mind.

 It's gonna happen sooner or later. Works well on the road!
|
 |
 So did 8 speed and 9 speed.
|
 |
 3spd Sturmy Archer is all you need
|
 |
 It'd be nice to fill in them stupidly big gaps in the sprockets, but it'd clog so easy, I have enough trouble with my 9spd mech!
|
 |
 I wouldn't say I notice big jumps on my MTB, just becomes and issue on the road.
Shimano hold patents on a 14 speed block and some kerazy chain to go with it, how long before that comes out!?
|
 |
 and how long will it last?
does that mean 56 gears then?
|
 |
 If anyone can point me in the direction of suitably-sized 10spd chainrings, I'm going to try it out with the road stuff (when it appears) and see how it holds up :-)
FWIW I like 9spd. Or rather, I like having an 11-32 cassette without massive jumps in it.

 Leaving my tandem out in the sun is enough to upset 9 speed indexing - I'm assuming its the frame expanding more than the cable that means I have to back off the adjusters. 10 speed isn't going to help things.
The number of MTBs I see with either no granny or a bash suggests their users find the current spread more than adequate.
The number of times I shift 2 cogs rather than 1 suggests the ratios are more than close enough together for me. It was only the 15-18 gap that bothered me with 7 speed.
10 speed {:^{

 Dont get me wrong, I love 10spd, but its suitability on a mtb is questionable.
|
 |
 Questionable yes. Probably a mistake yes. But I'm not going to dismiss it out of hand.
I agree with John that the current gear range is more than adequate, although people doing without a big ring are deliberately sacrificing top-end gearing for ground clearance rather than making a point about gear ratios, I think :-)
|
 |
 'does that mean 56 gears then?' i'd say no, at the mo IIRC (and correct me if i'm wrong!) you can't run a 10 speed with a triple ring on road bikes, only 2 rings. (BTW, 42, not 56)
as i said, i could be completely wrong!
|
 |
 Hmm 10spd. Me see a Middleburn duo on the horizon to make use of them all. I've more than enough gears with 27. I rarely use the full range anyway.
Road with two rings yes, mtb with three rings and mud ???
|
 |
 I'd just try it with 9 speed rings Mike, sure it'll work. SRAM 9 speed chains work on 10 speed after all.
|
 |
 I've run my 10spd on 9speed rings (for one ride of 113mi) and it worked fine!
Marv, there are 10spd triples in the form of the Ultegra cranks and the soon to be released Dura-Ace triple.
|
 |
 "I'd just try it with 9 speed rings Mike, sure it'll work"
Worth a try, I guess ;-)
|
 |
 ah. i'd only seen the dura-ace ones. thanks.

 TBH, I never use anything above 44/14 and rarely use 22/32. I've often thought about a 'low hassle' drivetrain with an 8 speed chain, a single 28-30ish tooth chain ring and an 8 speed cassette that goes from 12 to 36. Big jumps in the cassette never bothered me - fucking about with maintenance and chain suck and crap covered gears does.
If you can get away with single speed then why not 8 gears?
|
 |
 '8 speed cassette that goes from 12 to 36' where you gonna get one of them!?
|
 |
 Also, a 8speed supporter 11-28 would do me, rarely use my 22/34.
ROHLF only way to go, for No bother maintenance, someone wanna give me £700 ish ??? PLEASE :)
