HUP Kids Cranks: Children's Short Cranksets (104bcd 4-bolt) Narrow Q-Factor

Regular price £70.00

ARRIVING IN AUGUST...

Finally, lightweight and short cranks for kids with a narrow Q-factor and a 104bcd 4-bolt layout for chainrings from 30T to 38T. These HUP Kids Cranks are probably the most important component you will fit to your childs bike!

Get it wrong and they lose pedal power and risk injury from crank arms that are too long or wide. Get it right, and they will spend many happy hours in the saddle and maximise their little leg power!

Available in a variety of popular lengths to fit junior/youth riders from age 7 to 13 approx. Compatible with any JIS square-taper bottom bracket, they are cold-forged from 6061-T6 aluminum for strength, low weight and durability.

These cranks are perfect for Road Racing, Cyclocross, Triathlon, BMX or MTB with the appropriate bottom brackets and single chainring, which can be mounted inboard or outboard of the mounting flange to suit chainline requirements.
