    Would this work? Using a rear derailleur as a tensioner for a single speed full sus

    Hi all,

    I am currently building up a Snabb T. However, due to having limited amount of money and being too excited to get the bike. I am currently still waiting on the final parts to arrive which are the wheels and brakes. I decided to go with a single speed option first before buying a proper groupset instead of cheaping out on it.

    For running single speed, I bought the cheapest derailleur I could find which was the Sram x3, as for the rear cog, I bought the Gusset 1-ER Single Speed Conversion Kit.

    I was wondering if this would work on the trails or do you think that it would not be viable and the chain will fall off.

    Thank you.

    I'd go for a short cage derailleur with a clutch to help with chain retention.

    Eg. Shimano Zee.

    i would think a singlespeed tensioner would have been cheaper then a rear derailleur

    indeed, a tensioner like Blackspire or DMR will likely be cheaper than a crappy derailleur, and it will work better.

    A sprung single speed tensioner with a clutch would be sweet.

    I was about to order the DMR chain tensioner but saw that there isnt a spring so I thought it wouldnt work with a full sus. Are you talking about this (DMR Simple Tension Seeker & Single Speed Kit | Chain Reaction Cycles) or (http://www.blackspire.com/qs/product...7/263221/0/0)?

    Keep it tight, or your chain could jump.

    Not quite that tight though.
    Not if you still want your suspension to work.
