Our long time project, the Wheel Slammer, is finally out and available.

The idea for these has been started out a long time ago, coming from balls from looseballbearings and what not stuffed in the gap between the axle and the dropout to keep the wheel from sliding forward.

Once you have worked out how much of a gap you have between your axle and your dropout you just get that size and plug it in there.
On the picture shown to the right you see the 4.5 * 5.0mm. The slammers come with two sizes in one to leave a little option with play to you, they start at the 0.5*1.0mm and go all the way up to 7.5*8.0mm.

Thecomeup posted a block about the slammers too, and it seems that it has been hard for some people to understand how they work. They don't actually slam your wheel in the sense of making your wheelbase as short as possible, but once you have them in your wheel can no longer move forward, which is what we mean by calling the wheel slammers.

They are done in Aluminum and the weight is next to nothing.
