Having your bike serviced? Upgrading? Have old parts taking up space in your garage? Donate your old bike parts to Access Bike. Here at Slam69 we have a collection point for any donations you may have. These guys are creative and innovative, even if parts are no longer fit for bikes, they will create something awesome!
Recently they organised a pub quiz fund raiser which raised them enough money to buy not one, but TWO new work stands, we were stoked to be able to help them attain a bargain price and order these in for them.
