Re: [RBW] Re: Clem RD Chain Tension
I used a medium cage XT (clutch) shifter on my Rosco build, and it has been fine so far. 11x34 in the rear, and 50/34 up front. The only issue is the new KMC chain wasn't long enough, so I had to splice in a few more links.

Re: [RBW] Re: Clem RD Chain Tension
A few years ago on a club Metric Century the guy I was riding with dropped his chain and in the process managed to twist a link. As a result the bike was constantly upshifting then immediately downshifting. Finally we stopped, took out a chain tool and removed the bent link. I told him that would be fine as long as he remembered not to use the big-big combination. The route happens to end on two hills. On the final hill, he forgot and accidentally shifted into the big-big. Derailleur jammed in that position and wouldn't shift down. It took us a half hour by the side of the road to get it so he could finish the ride. As for quick links - the ones I use, that come with SRAM chains, work fine. I've been using them for many years now. On 11/14/2016 11:32 AM, ian m wrote: Do you risk it ripping off if you use big/big from time to time? -If by it you mean the derailer, it's doubtful.

I would rather break the chain with a tool and reattach it that way then try to get those quick links to work.

Do you risk it ripping off if you use big/big from time to time? -If by it you mean the derailer, it's doubtful. As long as the derailer is still providing some tension, meaning the chain is not so short it is pulling the derailer up, and shifts into and out of the largest cog, you should have no problem. My Altus derailer looks the same on my Clem. I also used two chains (really only like 5 links from a second chain) with only one quick link as I hate those with a passion.

[RBW] Re: Clem RD Chain Tension
There is little risk of ripping it off. Its a little tighter than ideal but adding a whole link would be a bit much. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Clem RD Chain Tension
The long stays might mean you need more tension on the chain than you would
otherwise. I'd look into a clutch style MTB mech. Otherwise, the GS is
the short-cage Shimano and you may be better off with the SGS which wraps
more chain.
