nolipoli Posted July 1, 2013 Share I recently changed bikes from a Giant Reign with an XT Shadow PLUS rear derailleur to a Giant Trance X 29er with a SRAM X9 Type 2 rear derailleur. I AM SO DISAPPOINTED!!! The Reign never lost its chain, and I rode a lot of gnarly rocky trails on it. It was quiet and efficient, and I was always confident that I could just mash on the pedals after a rocky descent. Now I am losing my chain all the time. The chain slaps all over the show, making noise and generally effing with my chi. I have to look down all the time to make sure that the chain is actually on before I can pedal again. The chain is the original factory length, and the whole drivetrain is still new. Did SRAM just miss the boat, or is there something I have missed?

usxorf Posted July 1, 2013 Share I don't get chain slap but I drop my chain all the time(off the big blade) . It happens if I just lift the back wheel and drop it. Might just be specific to the trance 29er 2 setup. Link to comment Share on other sites More sharing options...
Capricorn Posted July 1, 2013 Share been using SRAM X.9 Type II on my trail bike for a long time now. Haven't dropped a chain in the gnar once, especially during the recent enduro events. Did it's job superbly. Maybe your one is a bum mech? but on a 26" Trance. Edited July 1, 2013 by Capricorn Link to comment Share on other sites More sharing options...
madmarc Posted July 1, 2013 Share When you say you losing your chain, I assume you mean off the chainrings. If that's the case it's your front Der. that needs setting. I just installed an XO type 2 on my 2 X 10 setup and very impressed with the way it works. I also did a lot of reading up on the type 2 and the SRAM system was a lot more popular than Shitmano.

Capricorn Posted July 1, 2013 Share the one major difference between the two friction clutch implementions, is that the shimano offers adjustable friction, whereas the SRAMs is factory set. I initially thought the lack of adjustment would become a PITA, turns out not to be the case: works just fine. Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted July 1, 2013 Share Noli - is your chain the right length? I know from personal experience that a chain with even 2 links too many has a dramatically higher chance of coming off than one of the right length.

Use the over big blade and biggest cog method for measuring it. Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted July 1, 2013 Share +1, sounds like a chain that is too long. Use the over big blade and biggest cog method for measuring it. Yes. And in this config the RD must be stretched like hell. Almost to the limit. Link to comment Share on other sites More sharing options...
Ysterperd Posted July 1, 2013 Share agree with Armpies; check chainlength ( I had to remove 4 links) - have not had a day's problems since fitting my X9 type 2 six months ago. Link to comment Share on other sites More sharing options...

Capricorn Posted July 1, 2013 Share Bad Noli. come blame the type 2. Public lashing with original length chain for you! Link to comment Share on other sites More sharing options...
usxorf Posted July 1, 2013 Share Being a dual susser big+big chain sizing needs to happen with shock depressed, otherwise you might be in for a surprise going over a bump or drop. Captain Fastbastard Mayhem 1 Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted July 1, 2013 Share Shouldn't they cut new bike chains to length? They don't. It's also frame size specific. Longer seat stay = longer chain etc. Far easier to just put a generic uncut chain on the bike. Also - it would imply some sort of initiative.

Good point, Yazzo. Noli - let all the air out that shock of yours and check the chain length. adjust, cut and reinflate. It's a pleasure. Link to comment Share on other sites More sharing options...

Captain Fastbastard Mayhem Posted July 1, 2013 Share LBS should have done those small things ROFL. Never, dude. Only a few select LBS's actually do that. They should do that, yes. Do they? No. They should also fit a quicklink once done. Do they? No. Again, a generalisation M L 1 Link to comment Share on other sites More sharing options...
