/ Road Bike sizing.
I'm 5 feet 9inches (and a tiny bit), 31inch inside leg. Anyone of similar dimensions, what do you ride?
54cm sounds ok. That's what I've got and I'm about 5'8"/5'9". I would expect you to need a 100 or 110mm stem. Make sure it's got the maximum 3cm of stem spacers to allow playing about with the height. I have to say my back isn't fit for the generally lower modern bar positions so I have got my stems sloping up rather than flat.
Bianchi sizing I am 53. Colnago 50s. Trek 52 or 54. Specialized 54. I am 5ft 8 with a 30.5 inside leg. And a longer torso.
Have you ever looked at the fit calculator on competitive cyclist?
Not sure it's much help but I'm 186 cm or bit less than 6'2 n m bike has a tt of 57 so I would hint 54 "sounds" ok for you.
< 2cm going to make much difference?
Sounds big. 5'9 and a bit - old road bike, 23" in old money and 565mm top tube, tiddly 9cm stem to get the reach right. Rode it (many) years with a flat back position, always knew it was too big.
New road bike, medium compact geometry, 547mm ETT. Much happier on this.
Where's the front hub when you look down in relation to the bars?
Got any experienced mates that can take a look?
At the end of the day if it feels right it probably is right and vice versa.
That's one rule of thumb covered then. You're both right really. Yes 2cm can make a big difference but if it's not causing you problems - neck ache, etc - is it actually a problem?
