The mainstay tool of the Fixed Gear rider, the 15mm spanner is an indispensable item to have with you.
BLB wanted their 15mm spanner to be simple; it doesn’t need a bottle opener on it or a fold out chain tool, it just needs to work really well.
They've added a dual-directional 15mm Socket Wrench (ratchet spanner) to the other end, so as you don’t round your nuts off. Its also long enough to give you plenty of leverage and small enough to tuck away in a pocket. What more could you want?
