Are you sure about the 54? I'm 5'11 and ride a 56 I know everyone's different physiologically but Is a 54 not going to be too short for you on do you have a short torso with long legs or vice versa.

wrench science said I need a 55.5 top tube which is about bang on for me.

I'm just curious as to why you went for the 54> Top tube length? Bike sizing perplexes me!

It perplexes me somewhat as well!

Basically, I have a background in riding MTBs, so I am used to 'smaller' bikes, I think. I ride a 17" MTB,and a size 'M' Giant Compact Road bike, which both fit me well, but on the Giant I have the seat quite low and on the drops I still feel quite stretched out.

I got the tape measure out and measured all the bits and pieces on my current bikes, and I was on the brink between the 54cm and the 56 cm. I read a lot of comments which talked about the frames running quite big, and considering I tend to err on the smaller side, I talked to Pearsons and they confirmed that I would probably be fine with either.

Pearsons did also say that if it was too small for me I could bring it back in and they would see if they couldn't sort it out somehow.

I am a bit oddly shaped, so maybe that explains why I prefer odd sizes?

I deliberated for ages about this, but in the end, if it really is too small, it's not like it's the end of the world.

Also, echoing MidnightRambler, cheers for the spot LFGSS - wouldn't have noticed it if I hadn't been lurking on this forum so much lately.

Can anyone answer my earlier question about adding a fixed cog? I got the impression from pearsons that i could just thread one on, but then I got the impression from here that I'd definitely need a lockring? Also, how many teeth for a first-time fixed rider?
