I'm looking for advice and suggestions on converting a single speed this year as MABRA has a separate category now and it looks like fun. I took a look at CX mag issue two, they recommended the Renner tensioner but I have a steel frame with vertical Breezer dropouts so I don't think it would work. Soulcraft one looks good but a little pricey. The review did not include some more recent possibilities that I've found good prices for:
The DMR looks promising as the same basic design as the Renner/Soulcraft- no springs, sealed bearing roller. Any feedback on this or the Surly?
Also, suggestions for spacing/cog kits? I have both 130 and 110bcd cranks in the parts box, so could run a 36, 38, 39, 42 or 44 chainring in the box, any advantage to any of these over the others as a place to start a collection of 3 or so cogs to choose from? Thanks-
i would avoid the surly - avoiding springs is a good thing, but if you need a spring because you're changing cogs a lot, the paul has the pivot in the right spot.it's not hard to re-adjust the soulcraft for a 1 tooth difference, either (allen key).
i haven't tried the dmr - but if it's similar, go for it. i was the tester of these tensioners - and would recommend the soulcraft over the rennen just because the rennen didn't work on all my bikes.
or, you can try a magic gear?
