what gear ratio is that? and what is that gear ratio for?

34x14 gives 2 ratios on the S2 hub of 64" and 87" intended for keeping up with a chaingang on nice road bikes at work around the lanes.

I can (used to be able to) get up most hills on 64" and I can pedal at 30mph in a group (if I have to) on 87".

Found a picture ..

I bought a pair of nutted Tektro brakes for an old 27" frame. At some point a previous owner had drilled out just the fork for a recessed brake.

A neat,cheap and easy solution was using a Schrader / Presta adaptor designed to go in a rim.

An aluminium one was about a pound from SJS cycles (+ postage, but I was buying other stuff).

re my previous post.
The Hard Anodizing took nearly an hour to remove but the standard grade anodizing on some green alloy nipples took less than 10 minutes.

I stripped the Hard Anodizing off a dark grey quill stem that I wanted to be a better match to an old frame ....

I used the Caustic Soda technique that was well described here :

Followed by buffing with the budget polishing kit from :

I've just done my own clearcoat using POR-15 industrial/marine paint.

The finish isn't as professional as perhaps I'd like but it does show up the brazing and lugs on the 40 year old frame.
