Conversely, Dawes seem to have a more limited range of sizes for their various Galaxy bikes - for example they seem jump from 59cms which is too small for me to 64cms which is too big.gwhite said:The advantage of going with Thorn is that for each size of frame they provide three lengths of top tube. This is great for those of us who don't have normal proportions. Custom fit would be worthwhile in my opinion and worth the effort. Good quality too.
