10 speed cassettes

is it possible to run a 10 speed road cassette on a mountain bike to give you a 30 speed bike or would there be a chain line problem.
cheers thwang

You can, but you must have a 10speed shifter, you can achieve this
by taking dura-ace or campa downtube shifter and put them on a clamp
to fix them to your handlebars. There are some companies making
them for them thumpie addicts (think it was PAUL)

But then: Why Would You!! I Already stopped at 8speed, everything above
8speed just wears away before your eyes after every ride. Too narrow!
I don't see any added value in having two more gears or is it just for that
magic number 30?

I think you are also going to need a 10 speed hub . I though they were different forn the 8/9 a speed .

it is actually quite nice to run 10 speeds . Only tried on the raod , but it allows to keep a good rythm .

I'm using 7 speed shifters over 8 speed cassette's with either the 11t or the 28t limited out! I'm not good enough to worry too much about ratio jumps.

I've been known to do that that with no side affects... rarely use 1st gear anyway

Ok to get it clear for everyone :

7 and 8 speed systems are totally compatible, except you will
miss one gear (when 7sp shifter with 8sp cassette) or you have to
adjust the derailleur range (when 8sp shifter with 7sp cassette)

9 is different, there are nine cogs on the same width as the 8sp, so the
cogs and the space between the cogs are smaller. explaining the
ridiculous rate of wear of 9sp systems. It also explains way 8 and 9 sp
shifters are not interexchangable; the 9sp cable releas is smaller.
But 8 and 9 are compatible in another way: the cassettebody is the same,
you can interexchange the crankset, the front and rear derailleur (alltough
9sps' tend to be a bit narrower).

10 speed cassette is again based on the same width, but they don't always
fit onto the 8/9sp bodies! just to make it more annoying I guess. But I was
already resent the 9sp so don't even bother to go near the 10.

But if you go for an indexles thumb shifter you can put in 7,8,9 even 10
speed wheels in your bike without changing your shifters

Of course, it'd just be easier to use 10 speed flat bar shifters

Pricey though.

I knew 7 and 8 were the same and 9 was different...

I just meant I don't use 7, let alone 10

ahh, well done dave_h, I was looking for those!!

10 speed is great on the road, when you get used to it you go to an 8 speed and wonder where all your gears went!! Good for rythm
