The PRS20, or any stand that needs you to drop the wheel out are a waste of money. It really limits the work you can do. You couldn’t:
Adjust front brake
Service headset
Service front forks
Plus you have to drop the wheel out every time you use it – what a faff!
I’ve got this:
Bike Hut Stand
For the money it’s great, but had I seen the X-tools one, I’d have got that instead. It’s cheaper and a little more stable:
X-Tools Stand
The other parktools stands are OK, but really not worth the money. The best stand you can get is the bike shop stand by Kestrel – you can see them in the workshops of most bike shops. They are expensive (£450 last time I looked), plus they take up a lot of space.
