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), use 1x 2.5mm spacer on each BB cup and a 6mm offset chainring. Fitting to the HUP xc 13"-19" (73mm shell) use the 2mm spacer on the DS cup and a 3mm offset chainring. Fitting to the HUP xc20/24 (73mm shell) use the 1mm spacer on the DS cup and a 6mm offset chainring.
