Here's another race budget friendly offering from Excess that has a couple of surprises up its sleeve. The Excess Mini-Expert Rear Hub 24R has a 28 hole configuration which is perfectly suited for anything from expert wheels, down to minis and micros. Replace the standard hub on that entry level race bike with this sealed bearing offering that can be configured as a disc brake hub with the purchase of centre-lock disc adapter to future-proof your kid's bike.

It's becoming more and more common to see disc brake options being offered on after-market frames, even down to the junior sizes, and if you choose this rear hub from Excess, you can rest easy knowing that if you upgrade the frame, you can choose a disc-brake only frame, you won't have to build another set of wheels. You simply convert this hub, add the disc brake system and your pocket rocket will have one finger stopping power. It actually makes more sense for the youngsters to run discs with their yet-to-develop wrist and finger strength.
