Lately I've been thinking I need a granny gear on my Bullit, since I ride so many uphills and stunt trails. I'd like to run a 36T big ring and a 24-26T small ring. However, I cannot stand dropping my chain or other drivetrain issues. As far as I've seen the E-13 DRS is the only option for me. How is the reliability? Thanks!

I've been using a DRS for the last 2.5 years, and the guide is great. I'm running a 36-24 combo and shifts perfect and I've never dropped a chain.

Same here as Brian... lots of vegetation ends up inside my drivetrain and the drs keeps everything in place...

Other options are Blackspire Dewlie and MRP LRP. I'd stick with the E-13, myself. Only weaknesses they ever had were being noisy and having rollers crack, but the sleath roller solved that problem over a year ago...

I have also been running a DRS on my Heckler for about two years.
I used to have 22/32 combo but was not high enough gearing, now I run 22/36 and it is great. E13 recommends not running more than a 12 tooth difference between the two rings but it is working fine.

What's the reasoning for the <12 tooth thing? Possible chain-dropping or noise/rubbing?
I'm thinking about getting a DRS and I always run 22/36 - I think it's the best gearing ever for trail use.

36T-22T on my heckler and it works beautifully.

It's a limitation on the derailleur, not the guide. Shimano only recommends 12-tooth jumps between rings. More than that, and they don't guarantee it to shift well. They always work fine for 14-tooth jumps for me, and some people do 16-tooth without a problem.

Right - I'd forgotten about that Shimano thing.
thanks!
