    New question here. 2 x 1 ?

    Is it possible to run a single rear sprocket with two chain rings and a bashgaurd?. Will a chain tensioner take up enough slack to get rid of the RD, cassette, and rear shifter while keeping the FD and two chain rings with bashgaurd. This is for a freind who rarely shifts and constantly wrecks his RD, but would like to keep the two front gears for climbing vs flat trail.

    No. In order to take up that much slack your friend would need to keep the rear derailleur or run a Paul Melvin tensioner (which is as bulky as a RD). Might as well keep the RD.

    Paul Melvin tensioner:

    +1 to Saprty.

    keep the RD. put the chain on the larger chainring and remove excess chain, i mean to the point that the RD is almost horizontal. dont worry, you are not gonna break your RD spring.

    i will go for 1x2 though, throw your FD away.

    Paul Melvin tensioner seems like it would do the trick to run a 2x1. But how exactly could you run a 1x2? Run two separate SS rear sprockets with spacers and just leave the RD.

    Yes. Fishcreek's got the right idea. Surly's SS cogs have wide bases. If you stack them together you wind up with standard 9-speed spacing. You could use 2 or 3 or...

    Then ditch that chain sucking FD altogether.

    I have that setup on my beater bike and it works great. I use an old derailler rather than a tensioner though. It's cheap, readily available, and takes up a lot of chain slack just like it's supposed to.

    One ring, one cog. Walk it if you can't ride it. This is the only real solution.

    However, If one must run some gears, for the love of fair trade coffee, run a RD or better yet, a geared hub. I hate FD's more than life itself; worst bike component ever invented.

    Whoa. You just crossed the line. Take that back, immediately if not sooner.

    Just curious how your friend is wrecking multiple rear derailleurs? Crashing?

    yeah crashing, landing jumps wrong, hitting trees. Our local trail is really tight twisty single track "with a catastrophe waiting around every corner". We ride there enough to go faster than you should. My buddy can bunny hop, leap off and over anything. And on tight single track it always doesn't work out. He has probably destroyed 3-4 RD in the last few years. He only uses about two gears usually and has been interested in a SS for a while now. Right now he rides a DJ bike wich is the best thing for his style of riding..
