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.

Funny yet good bottle opener
Size: One Size, Style: Bottle Opener
Nice rubber grip. It would be better if the metal part was one inch longer, but still very functional.

The right tool for the job.
Size: One Size, Style: Bottle Opener, Size: One Size, Style: Bottle Opener
This is the tool you want. It is exceptionally functional, well made (made in the USA, if that matters to you), and beautiful in the way that quality tools are. The thing that really sets this tool apart is that it correctly balances form vs. function: a heavy duty build (as is the point when buying a bottle opener built by a tool company) without its use as a bottle opener (as is the point when buying ANY bottle opener) being negatively impacted by said build. I also bought the Craftsman bottle cap wrench, which, in my opinion, is hugely successful as feeling like a heavy duty tool and something of a failure as a bottle opener. It's so large and heavy, it has equal mass to the bottle you're opening. Imagine your buddy who has had one too many wielding a 12 oz. steel wrench over your tile floor, countertop, toes, etc. and you'll get the idea. Lastly, the engraving and materials on this Klein tool are so attractive I had to build it a custom wall mount instead of hiding it away in a drawer or tool chest. I will be buying a second for the office.

Good Tool
Size: One Size, Style: Bottle Opener
This thing is great at opening bottles, and it has a Klein handle. Perfect for the electrician in your life, even if that's yourself. I had to knock off a star because the handle is not quite as good as other Klein tools. The plastic is not as clear. The TIP-IDENT bottlecap marking is off-center and not fully printed. The bottle opener sticks out at a slight angle. This does not affect the performance, but it does detract from the novelty somewhat.
