    Long Cage, Rapid Rise

    I have a Deore LX rapid rise, long cage derailleur. It's a little noisy and when I asked a couple of my buddies at the bike shop, they thought it could be the pulleys. The thing is 5 yrs old and has about 30 K on it, but it's always been noisier than other rear derailleurs I've heard. Is that typical of this kind of derailleur?

    You may well want to pull the pulleys and clean/grease them real good if it has been 5 years. I haven't owned a Deore RD but friends have and I never noticed any excessive noise. Is it aligned straight through the cage and rear cogs?

    5 Years and 30,000 miles is a good life for any dérailleur so I would check to see how much play there is on the pivot points.

    It might be.

    Personally, I've never been high on rapid rise derailleurs because they rely on spring tension to pull the chain up onto the bigger rear cogs. I think that could make downshifts a little slower and noisier especially as the derailleur ages. If that's the case, a good cleaning and maybe a new set of cables and housings might help.

    In the interest of full disclosure, however, I have a son who rides a very high end freeride mountain bike. He LOVES his rapid rise derailleur and he's much more into mountain biking than me.
