Rapid Rise MTB Question(4 posts)

Rapid Rise MTB QuestionMudman

A friend brought over his bike and it shifts backwards from my other bikes. Is this because his XTR RD is rapid rise? Is there any way to reverse the shifting operation? The shifters are shimano XT rapid fire. Thx
Rapid-Rise would be marked RD-M953....TFerguson

Regular would be M952. New RD to change it is the only way I know.

If you want to change, you have to replace the rear derailleur. I mentioned a month or so ago that I didn't think that rapid rise was one of Shimano's better ideas. Several posters responded that they absolutely LOVE it. I guess that everyone gets to order his own breakfast.

You need to change the derraelleur in order to change it to standard mode. Most people simply hate rapid rise just because its not what they're used to. Tell your friend to give it a try first, he might actually like it far more once he gets used to it. I tried one for a while and ended up making all my mountain bikes rapid rise. It actually feels like the correct way to shift. With the spring pulling the derr. towards the larger cogs the shifting tends to be more accurate since the bigger the cog is the more sensitive it is to shifting wrong if you push a bit to far or too little on he thumb shifter paddle. Using the spring to shift towards the larger cogs ensures always constant pressure and exact shifting each time. Since you mainly need to jump several gears at once very fast only when you start downhilling after a climb, using the thumb paddle to ratchet 4 gears at a time with one stroke will allow you to shift down the entire cassette range in two swift strokes rather than having to slowly click the index button 8 or 9 times in a row.
