Hi all, Im planning on building up a new bike to be used for a bit of light touring and possibly as a single speed. The only frame I've found so far that seems to be what I want is the on one inbred, altho I can't decide wether slot (horizontal) dropouts or vertical dropouts would be better for what I want?

Does anyone have any opinions on this frame? or any alternatives I should be considering? Ally or steel will do, 26" wheels (so I can use the currently redundant components I already have), must be able to be built as a single speed, or geared, and MUST have rack (panier) mounts. Budget is around £200 tops for the frame only. Oh, and the cooler the better!!!

thaks in advance,

Ste

If you want a rear disc brake you'll want an eccentric Bottom Bracket rather than horizontal dropouts.

errr...... you've lost me here......whats one of those, and why do you need one for rear disks?

I'll probably be going for disks to make wheels from my other bikes interchangeable with it.

thanks

Because if your chain stretches, and they do.. you then need to reposition your rear axle (backwards) to take up the slack. With rear discs your calliper will now be in the wrong position and the disc won't fit in the calliper & your axle in the dropout together.

The way round this is to have an EBB (eccentric bottom bracket) that basically has a small range of adjustment to keep the tension in the chain and retain a vertical dropout arrangement to keep the rear axle & calliper in the same position.

The other way round it is to have variable calliper mounts but I've only heard about and not seen them.

that makes sense. Something else for me to think about then!



This is what Im looking at:

http://www.on-one.co.uk/i/q/FROO26INSLT2NDGEN/on-o...

It has rear disk mounts and looks like a normal BB to me! Appears to have slotted/adjustable caliper mounts like you mentioned?
from the blurb:

"running discs without any of the problems often associated with horizontal dropouts and discs,"

Cheers
