Twist? 17mm? Ah, that'll be the 17mm Hex Spanner in the end of the seatpost then. So, KisBikeCo want you to only need one tool in your pocket. The, unsung hero, the 6mm Allen key! With riders who use pegs, this became a bit of a problem. After working on slotted bayonet fixtures and all manner of crazy peg designs and ideas for months they realised they really cannot change the function and powerful design of a peg. They take too much abuse to start making them in two parts. So... a bit of reverse thinking and developed this idea. The Integrated 17mm Socket set and seat post! Basically, you use your 6mm Allen key to take your seat and post out. Your seat and post then become your socket set for your pegs. So simple, so functional, and ideal for road-trips, at home or abroad.
