Fixie Bike Shops

They don't buckle, and it is rare to see an Arrospok break (there is that one image of a snapped Aspok floating around the internet, but it had a truck reverse over it) in this respect they are very strong, good for doing tricks where you land heavily on your front wheel.

I actually know a guy that lives in San Mateo (just south of SF) that's broken three of the things. All from doing crazy trick stuff on them. I keep telling him to just buy a trials bike, but he won't listen.

He's a big fella, too. But he has (if you'll excuse the pun) exploded the myth of the Spok's indestructibility. In all three cases, he's sent the wheels back under warranty and gotten replacements for around $100, but I'm sure at some point Aerospoke are just going to write him a letter along the lines of 'Sorry, mate, you're having a bubble - here's your broken wheel back'.

I'd like to add my voice to the clamour of those saying that a HED/Spin/Trispoke is the way to go. Or a Mavic IO if you're really rich.
