How much benefit is there from having a frame designed for singlespeed? ie: If I just buy frame with vertical dropouts and stick a tensioner on it (if I can't find a magic gear), will I be much worse off than if I had adjustment capabilities?
Cheers.
There are lots of bewdiful SS-specific frames around that look a million bucks and are the sorts of things you get all warm and fuzzy about when you sit on them and there are some with pretty ordinary geo - like any bike really.
I've been running a SS with a tensioner on an old frame that I couldn't bear to part with for a long time, it fit me so nicely. Funnily enough, I like it better than my quite expensive SS-specific frame to munch up the Ks on, but its a personal fit thing. I've had no hassles with a tensioner, no dramas with unnessary wear on the drivetrain and it lets me change ratios pretty easily and quickly due to the couple of extra links in the chain I can accommodate.
At the end of the day a cheap frame is a cheap frame and an uncomfy frame is uncomfy irrespective of the shape of the dropouts.
