16/17" inch centre/top with an ETT of around 23" would seem about right to me. That and a 70mm stem probably.TGR":2ycnxynl said:Is the measurement of the seat tube different then from a road bike? I am trying to work out a size for a frame for my mate. He is 5'9'' with inside leg of 30''. What would this equate to in MTB frame size?
Or, will almost any frame do - just with a scaffolding pole for a seat post when required?
Thanks Mr Large Cheese
I very rarely see advice from you that I disagree with LGF, but I have to disagree here. Steering characteristics are very sensitive to stem length, so I would suggest that stem length should never be used to make a bike fit. And especially a longer stem should never be used to make a frame that is too small 'fit'. I wouldn't want a bike that 'fits' if the downside was that it had unresponsive steering.legrandefromage":25vp5j84 said:Its very easy to make MTBs fit due to the number of different stems available, add a long seatpost and you have a lightweight chuckable trail machine.
