Found a decent shop on eBay and got a deal on frame/wheels/parts

I got a bit carried away for the “BMX for a lanky unbendy 40 yr old” earlier this year and bought a 22″ BMX from the US.
22.5″ top tube AND 22″ wheels. Less twitchy that a 20″ but way more fun than a 24″

Awesome! Thanks for the advice

I’ve been to the DH twice. Twice because,like an idiot I broke my arm on the 1st day,this was totally my fault though.
Michael,the guy who runs it all offered me a free return trip. He kinda messed me around for nearly a year when I tried booking my return trip but he did eventually honour it,but it did put me off a little.
The trails themselves are well worth it though, there are some amazing long super technical descents and it’s a lot rougher than I’d ever imagined.
I plan on going again next year but might see what Roost DH is like,heard some good things about them.
