I was just having a look at BC Wheels from around the place and noticed on: http://www.unicycle.co.nz/View.php?action=ProductDetail&Code=BCWheel
It has 3 holes so you can change the height… (Choice of three axle holes, allowing different footplate heights of 45mm, 65mm and 75mm from the axle)
If it has a 14mm axle (Quando TX 48-spoke freewheeling BMX hub with 14mm axle ) each hole has to be 14mm wide.
Unless i am missing something surely there isn’t enough room for separate holes between 65 & 75mm as you would need at lease a 14mm gap between the holes. (7mm goinng up and down from the centre of each hole)
Is the top two holes actually a slot?
