MacAskill Block is an extremely versatile, durable tool designed to meet the needs of pro trials rider Danny MacAskill. The CNC-machined I-Beam body design is lightweight and rigid. The forged Chrome Vanadium bits are nickel plated for durability. The long body and 8mm Allen bit provides ample leverage for tightening cranks and pedals. The offset wrapped bit design allows for a compact tool profile. Danny’s signature is CNC-machined into the body of the tool, proof of his approval.
