Lightweight hollow axle cranks to fit any frame! These HUP 2-piece cranks are probably the most important component you will fit to your bike.

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

Available in a variety of popular lengths to fit junior/youth and adult riders from age 5+ Compatible with 24mm Shimano type external bottom brackets, they are cold-forged from 6061-T6 aluminium for strength, low weight and durability.

These cranks are perfect for Road, Cyclocross, Triathlon or MTB XC...as they use a slightly longer MTB axle, so are compatible with Road 68mm with spacers* and MTB 73mm BB shells.

Top Tips: as with all our kids cranks, we always add helicopter tape to the face of the crank arms to protect from kids feet rubbing (especially without cleats) when the cleat position sets the shoes very close to the cranks.

*Fitting to the HUP evo (68mm shell, non-boost), use 1x 2.5mm spacer on each BB cup and a 6mm offset chainring. Fitting to the HUP xc 13"-19" (73mm shell, boost) use the 2mm spacer on the DS cup and a 3mm offset chainring. Fitting to the HUP xc20/24 (73mm shell, non-boost) use the 1mm spacer on the DS cup and a 6mm offset chainring. You can also use 24mm axle spacers for press-fit type, Road bottom bracket installations. However, frame tolerances may override these - so ensure you use the correct spacers to acheive your correct chainline and crank arm spacing!

If using HUP cranks on a non-HUP frame, use the dimensions below to check for fit on your frames chainstays...width of inside of arms = approx 128mm. More install info here.

Great, solid toy safe for my dog
Size: Large, Color: Blue, Size: Large, Color: Blue
This ball is great! My pit bull love toys, especially ones with squeakers, but she’s a power chewer and trashes them almost immediately. Since she’s got a history of swallowing foreign bodies, this means she’s rarely been able to have toys, and when she does get them, it’s short lived. She LOVES this ball and it’s already lasted multiple weeks with no signs of any damage, despite the fact she carries it everywhere and chews on it daily. We don’t have to worry about her safety with this toy, because it’s large and tough enough she can’t swallow anything. It hasn’t lost its squeak either despite all her tough love. She loves to play with it and we’re getting more of them asap so she has a backup if this one gets lost or eventually does break.

Truly indestructible
Size: Large, Color: Blue
They are not kidding, this ball is truly indestructible. I've gotten several for my dogs so they have plenty to share. Two of my dogs are beyond super chewers (bully breeds). One of the balls is missing the section that's glued into most of them, but the structure has still held up. And my dogs LOVE them.

Tough STINKY ball
Size: Large, Color: Red
This ball is the only one I've found that my dog can not destroy in seconds. He can chew on it for a few weeks before he works a hole in it. That's the good part. The bad side is the horrible smell! It doesn't seem to bother him, but it is horrible to my nose. It is so awful that I tried soaking it and dish soap and vinegar water overnight to see if I could make it go away. It was a little bit better but still stunk. Anybody got other suggestions on what could make the smell go away?

A good toy for chewers!!
Size: Large, Color: Blue
My dog loves this ball! The best part is that he hasn't destroyed it yet. He's a real chewer and has destroyed several toys since I got him about 6 months ago. The ball is very solid and a the squeak is not annoying. A great toy

My dog loves it, holds up well
Size: Large, Color: Blue
My German Shepherd absolutely loves this ball! He is a pretty aggressive chewer and it has held up really well, not indestructible but it lasts. We currently have three and he always has one in his mouth.
