Im 6.3 ft and most my length is my legs 93 cm inseam.roughly from center bb to top sadle is 84 centimeters
I looked at you cdale photo and by looking at it i cant imagine you loving climbing in granny gear !your seat looks like its right above your rear hub.
Thanks for the concern
You'll be pleased to know that my saddle has gone up 1.5cm since that photo, but even on the road, despite my height, I only run 79cm saddle height - that's what works for my body and pedalling style. It sounds like you and I are on opposite sides of the leg-torso balance, but because of the long stem and drop, I've never had an issue weighting the front wheel on the C-dale set-up, or others I'd raced in similar position.
Perhaps that has been the big difference. On set-ups like the above, the front wheel has been relatively close to me in the past, so it's easier to get my weight onto it and carve through, while it's still possible to pick it up fairly easily for manuals. If I kept the same reach and position over the BB (required to keep my knees happy - they can be a bit temperamental), then unless I'm looking at this completely wrong, that should make it harder to get as much weight on the front wheel. Right?
Either way, it's becoming more and more clear that I just need to get on a few bikes to feel these differences for myself... but I'm still enjoying all of this discussion!
