The Shimano XTR Rear Derailleur—precise shifting every time.

A missed shift can mean the difference between a podium finish and standing in the crowd. The world renowned Shimano XTR Rear Derailleur has helped scores of riders do the former. Thanks to the XTR Rear Derailleur's ultra-precise shifting, it has made it a favorite among racers and serious recreational riders. As Shimano's top of the line mountain bike components, the XTR remains the top pick for top riders.

Hey there, what do you think of the Shimano XTR RD-M970/M971 Rear Derailleur?

Here's what others think:

What is the difference between the Top a October 4, 2010

What is the difference between the Top and Low normal?

answer

I could try and articulate the answer and potentially fail to make any sense....so I found one that is already well written here. Enjoy.
http://en.wikipedia.org/wiki/Derailleur_gears

"High normal or top normal rear derailleurs return the chain to the smallest sprocket on the cassette when no cable tension is applied.[9] This is the regular pattern used on most Shimano mountain, all Shimano road, and all SRAM and Campagnolo derailleurs. In this condition, spring pressure takes care of the easier change to smaller sprockets. In road racing the swiftest gear changes are required on the sprints to the finish line, hence high-normal types, which allow a quick change to a higher gear, remain the preference.

Low normal or rapid rise rear derailleurs return the chain to the largest sprocket on the cassette when no cable tension is applied. This shifting system was developed by Shimano in 1998 with RD-M951 and can now be found in most mountain groupset derailleurs from XTR to Nexave.[10]

In mountain biking and off-road cycling, the most critical gear changes occur on uphill sections, where riders must cope with obstacles and difficult turns while pedaling under heavy load. This derailleur type provides an advantage over high normal derailleurs because gear changes to lower gears occur in the direction of the loaded spring, making these shifts easier during high load pedaling."

I could never have said it so well. Thanks wiki.

question

I am running an XT 9 speed cassette, 11/ September 25, 2010

I am running an XT 9 speed cassette, 11/32, and 22/32/44 front rings. Can I run a short cage rear? Or do I have to go long?

answer

Shimano recommends you use a Long Cage with a triple crank.

question

Anyone remember which one was the 'Rapid March 31, 2009

Anyone remember which one was the 'Rapid Rise' (or backward shifting as my friends called it!) derailleur? Was it the Low Normal or Top Normal? Can't quite remember.

best answer

The Low Normal (RD-M970 SGS) is the "Rapid Ride rear derailleur.

4 5

This rear derailleur design was the standard for years and works great. It still works really well but I think Shimano outdid themselves with the Shadow. If you're using dual control get this derailleur.

question

Anybody know compatability with DA 10 sp February 19, 2009

Anybody know compatability with DA 10 speed for cyclocross applications?

best answer

Hard to verify in print, but I believe the swing arc for 9 and 10 speed rear derailleurs are identical. So it should work perfectly....KC
