Thanks for the input guys, you’ve just given me an idea (not at all what you’re expecting) and I know just the person to go and develop it, an obscure artisanal crank developer who’s already personalised cranks for national track teams competing at Olympics and WC.
May get back to you one day.
The crank aspect is big in cycling right now, I don't like the way manu.s spec near 172.5 cranks on all bikes of 'normal size' unless big it small. It'll take a forward thinking manu. to offer various crank lengths. I've contacted a few to ask if they can offer different sizes and nothing..no wonder the bike industry is in retrograde movement
Right. In a few years it will be widely acknowledged that expecting the range of 170 to 175 cranks to serve every thing from 150 cm to two metres tall was ridiculous.
Even 170 cm tall, 170 mm would be still too long. Even for 180 cm tall or taller. I guess those 170 mm cranks are meant for taller people, probadly.
Why this range? It seems weird. We could also have chosen 150-160, or 180-190 crank range to serve everyone.
We long know that bikes need to come in multiplw sizes so why not cranks. Same with shoe sizes (one size does not fit all). Handlebars have long come in sizes from 44-38, now narrower even 36 or smaller on track.
Also wheel sizes being the same for tiny riders vs big tall riders is also weird. Very small riders my not be able to get low enough on the front end to be competitive aero (think about like 150cm tall people). Big riders could benefit from larger wheels because the bike would look more proportional.
So dumb only bike frames come in many sizes. Kids bikes havevdifferent crank lengths, wheel sizes and hadnlebar widths. Heck, even mtb have different wheel sizes. Why not road?
Yes. They should sell bikes with out cranks and saddles, then when you buy it they can put on the crank length and saddle you want, or go cheap stock ones. It saves on money because you don't buy two sets of each.
Same thing with handlebars but that is a tough one to change. If anything that is okay if it comes stock with size "x" handlevars, definetly not 44cm on all sizes though. Canyon has the width adjustable aero ones, which is awesome.
