ive been geared riding with a 34/50 11/23 double recently and 5kg
on a light bike. im always in the 34, either at the bottom of the cassette
for climbing, or right at the top for flat riding. the big ring only gets
used occasionally on a long downhill. not ideal.I use 34/50 12/25 on both my audax and my race bike. Occasionally I pull out the 16 and stick a 28 to get 12/28 on the audax, and every so often I think about replacing thr 12/25 cassette with an 11/23 on the race bike. In both cases though I use the big most of the time and the 34 only for uphills.
So, I'd agree with domyracer, replace your cassette with a 13/29 (or whatever appropriate given the manufacturer and model, 12/27, 12/28, etc). You'll hopefully find the big ring becomes usable for most duties and plenty of scope on the little ring for the steepest climbs. Its also a much easier option than changing the crank to fit something smaller than a 50, or going triple.

ouch :(
If you've tried getting lube in from the top, you could also try tipping some lubricant - "plus gas" would be my choice - in from the bottom bracket, with the bike upside down; leave 24 hours. Otherwise, as above, gentle gentle heating.
After that I guess you're putting it a vice and twisting...
good luck!

Hi
Very interested, just not sure of the size (I take a 58cm top tube in road/race bike, which would point me at the large/62.5 on the charge, but I'm not entirely sure how the geometries compare). I'm in marylebone - how central are you? (i.e. if you live round the corner, can I come and have a sit on it? :) ). Otherwise I'll get my backside into evans etc and grace their stock with my backside...
Cheers
Jon
Very very nice. There was a fantastic 953 frame in Roberts last I was in there - carbon forks though, which would need replacing with these :) For me, 953 for the race bike, Ti for a sportive type thing
