Bike sizing
« on: February 04, 2011, 06:33:03 PM »
I have just sold my partners thorn eXp and I am a bit concerned about the sizing.When I listed it on ebay I had over 50 questions all relating to size of frame and height of rider which was to be expected,my reply was that the frame was a 560M and that would suit somebody from 5'7" to 5'11".
 The winning bidder turned out to be 6'1" and when I expressed my concerns regarding fit I suggested he contact SJS,I was surprised with the reply ,he stated that when he phoned them they said that the bike would be fine for him , do you think it would be OK for him as I am meant to deliver it on Monday (a 6 hour round trip) and dont want to get there and find out its too small

It might be a matter of torso length. Long legs can be accommodated by raising the seat post. The height of the grips needs to be considered too, though I suppose there are some extenders stems that can raise the bars even if the steering tube is a bit short. It seems the virtual top tube is the most invariant property of the bike. One can push the saddle back and get a long stem... switching from e.g. comfort bars to drops would create more length.

I would say, if he's got long legs he's probably OK, but if instead he's got a long torso, it gets a lot riskier.

I'm 5'11" riding a 565L Nomad MkII with comfort bars and quite happy with it. I would say I have short legs and a long torso.

I guess it's up to him ,his money after all !
Don't think he is going to be able to ride home from the train station though as planned ,as you can see it has drops with bar end shifters ,his knees are going to be changing gears for him.

Hi guys,...
Frame size has more than 1 component. You may feel comfortable on a 58 cm frame if the top tube isn't too long, and you might feel equally at home on a smaller frame size that has the same length top tube. Different bike companies manufacture their frame using different frame proportions and different methods of measuring their frames.
i hope this will helps you guys,..

regards,..
