Backbone is the sickest place to get any Bmx gear where that’s race gear or freestyle gear it’s my number one place to go when buying Bmx stuff!

Fully sick

Great helmet and fits great. Haven't bashed my head in for full testing but don't plan on it. It also looks better with a sticker 😄

Great Experience

There was a mixup for a hard-to-find part shipped to the USA. I called and Rhys picked up - he quickly came up with a generous resolution and resolved the issue. Rhys definitely cares about the sport and his customers. Makes me wish I lived closer. Thanks!

Redline MXII vinyl pad set

These pads are the authentic ones from back in 1980. The V-bar handle bars pad fits great. The pads in general are Snow White, with the “REDLINE” signature lettering for the model of that year. I’am very grateful I’ve found these pads for my REDLINE restoration project. I’m very happy with this purchase.

Perfect for flights

I bought this bag so I can fly with my bike. No issues so far, length will qualify it as over sized but until the weight limit is below required it should all be an easy flight with no extra charge. I only tried it with Qantas so far and only internally in Australia but so far so good. I fit helmet and bike tool with a pump in there easily. Only thing that you might want to add some rugs so the forks don't scratch up the paint on the frame. Very good quality, top stuff! Heavy duty and nicely rolls around with its big wheels.
