SShimano XTR M970, M971, M972.... what is it?

[blingUK]

Hi please help!

I'm trying to buy parts for a bike using Shimano XTR gear.

Can someone advise me what the differences are in the M970,M971 and M972?

I want to use rapidfire shifters and V brakes. What are the following that I need:

Rear mech
Front mech
Levers
Chain
Cassette

RD-M970 -- traditional slant parallelogram - RAPID RISE
RD-M971 -- traditional slant parallelogram -- "road" style cable pull
RD-M972 -- "Shadow" parallelogram - RAPID RISE

BTW. These are available with LONG (GS) or VERY LONG (SGS) cages.

But, FWIW, instead of the XTR components, I would be inclined toward XT components ... so, would be inclined to getting the RD-M772 (XT) rear derailleur instead of the RD-M972 rear derailleur. I don't have any "Shadow" rear derailleurs, yet, but I like the design. If you were inclined toward a rear derailleur with a standard parallelogram, then you could just get an older, XTR 960 rear derailleur.

And then, I think you should consider spending the "extra" money on (something like) a MARZOCCHI BOMBER fork + a set of wheels with really nice hubs (e.g., DT 340 ... or, almost any Shimano hub) if you don't already have set.

Now, preemptively I will say (in case anyone recommends SRAM) there are a couple of reasons 'I' wouldn't buy SRAM ... one is the really poor customer service in North Amerca (I guess that "support" is great if you are a sponsored rider) ... but, more importantly, Shimano is so universally available, now, that if you need a spare or cheap(er) replacement part, you can walk into any shop & get a replacement-or-substitute at the price point that you want to pay at the given moment in time.
