I've never really understood different crank lengths. If you think about it, the difference between a 170mm and a 175mm is, what, 3%? Can that really make a significant difference? Put it another way, your legs are pretty long...5mm is tiny. Even a cm is really small, and 5mm is half of that. That's really small. I've ridden 175s, 170s, even different lengths on each side, and I've never noticed any difference. FWIW.

What, between a roadbike and a track bike? Really?
My Moulton Mini has a single 49" gear. 14" wheels with 52 ring to 15 sprocket. One would think that would be bloody easy to ride. Yes it is along the flat at a constant speed.
When accelerating and climbing, due to the 5 ½" ( 140mm ) crank length, I have to put more force on the pedal to get the required torque at the BB.
I have a spare 46 tooth crankset with a 6 ¾" crank length. Do I install these and a 13 tooth sprocket to make a 50" gear that I can ride on a sportive for a joke? Or leave the bike standard for a 4'10" little person?
Sportive here I come.

Thinking about it, there weren't many Bradford on Avon Minis built with Sachs Torpedo coaster brakes in Pillar box red.
Most Minis were abused ( children ) and the rear rack bent by passengers.
I might have a rarity, especially with a Garmin Edge 605 fitted.
I reckon I could keep a steady 12 mph on a 50" gear, averaging about 8 mph overall.
I will have to start training.
