Looking for recommendations on a new "clutch" rear derailleur for my drivetrain which is currently all Shimano with a 10 rear and (currently) 3 front rings. Looks like the Shadow+ stuff is what I want, either XT or XTR. Need to find out if I need long cage (expected) or medium.

thanks for any tips

If you have a triple up front you need a long cage. I think the only time they say you can use a medium cage is if the difference between your 2 front rings is less than or equal to 10 teeth.

I had a clutch derailleur (XTR) on the loner bike I got. It was nice. I imagine the XT one is just as nice (and a whole lot cheaper)

I've heard that sram and shimano use the same shift ratio on 10sp, but haven't tested it out yet.

Clutch rear der's are the best MTB invention since disc brakes. Get one!

Ditch the triple while your at it, you don't need 3 rings up front. Both Sram and Shimano are good, can't gp wrong either way but I'm pretty sure you have to match the shifter with the der so that will determine which brand to go with.

Personally, i think the new XX type front chainrings with a clutch der are the way to go (1x10 or 1x11). No front der, chainguide etc needed. This makes maintenance so easy its ridiculous and I have never dropped a chain since spring time using this setup

XTR is $220, 214g: http://www.jensonusa.com/Rear-Derailleu ... Derailleur
XT is $110, 258g: http://www.jensonusa.com/Rear-Derailleu ... Derailleur

I think I'm sold on the XT long cage in black.

Oh, just saw your reply. So I'm going to do some calculations...but I'm not sure I can go single ring in the front...maybe double. There are some hills where even my current granny doesn't feel low enough!

Right now I have 42/32/24 up front and 11-36 in back.

Heading out for a ride...write more later.

thanks

I have been running a single ring up front all year. I have a triple ring crank with a bash guard and a 30tooth ring on the middle. No little ring. I have a x-9 clutch derailleur. Running that with the 30tooth wolf chainring I have not dropped a chain all year. It is a great setup for around here. Rode it at Holyoke, millstone, Kingdom and all over Stowe and so far I have not "needed" anymore. A few time I have wanted more gear but I have not had to walk because of the gearing yet. I highly recommend the 1x10.
