Sora chainset for MTB commuter??
The 8spd chainset on my Giant Escape M2 MTB is knackered and I was wondering if I could replace it with a Sora 8 speed chainset to get more top-end?
The current set-up is Shimano TX71 28/38/48 chainset with Shimano HG70 11-28 cassette.
The replacement chainset would be Sora Triple 3303 Square Taper 7/8sp 170mm 30/42/52.
I have Sora on my road bike so could test it if necessary, but would prefer not to if someone knows for certain.
Thanks

The Sora chainset would definitely fit, as Shimano parts are interchangeable, but you may have to fiddle to get the front-mech to work.
An MTB front mech will be too small for a 52 ring and the indexing is different on Shimano MTB and road front mech's, so if you fit a road mech it may take some fine-tuning to make it work.
I am puzzled why you think you need a higher top gear, 48-11 is 113 inches so you would still be turning the pedals at 30mph+ and 52-11 is 122 inchs which would be good for 35-40 mph. If you're reguarly riding at those speeds on an MTB then I suggest trying for a late entry in the Tour de France!0 -
As sjcp said you can't be spinning out you gearing on a MTB and if so pick up the phone and ring all the pro teams as you have legs like McewanRacing is life - everything else is just waiting0

Point taken[:D], however I did loose some of the original top-end when I changed to lower profile 26 x 1.0" tyres.
Are there any chainsets that are suitable for a MTB that go to 50T. I would prefer not to spend any more than œ25 as it's only my commuter.
Ps. I did get the MTB up to 38Mph on a Richmond park downhill.

Thanks for the offer SPD, but I have decided to stay with the original set-up and have ordered a TX71 28/38/48T chainset for œ18 delivered. It worked out cheaper than any alternatives and I know it works. If I want to ride really fast I'll use the Allez.
This time I'll change the chain more regularly so I get more wear from the chainrings / cassette.
