Recessed stem bolts and tight clearances around derailleur limit screws force you to work with tools at awkward angles. Standard multi-tool bits measure around 30mm long, which leaves you reaching through narrow spaces or fishing around bolt heads when adjustments are needed. The RAP II 18 from Lezyne extends bit length to give you better access to hardware buried inside frame junctions or tucked behind brake calipers. When you're dealing with a loose cockpit bolt on a gravel road or adjusting shifting before a race, the extra reach means you can see what you're working on and feel when the bit seats properly in the bolt head.

The machined aluminum side plates hold 18 functions: seven hex sizes from 2mm to 8mm, two Torx bits, a Phillips driver, chain breaker, 8mm and 10mm wrenches, and four spoke wrench sizes. The hex selection covers most cockpit, brake, and drivetrain hardware on modern road and mountain bikes. You'll find 4mm and 5mm bits for stem faceplates and seatpost clamps, 3mm for brake calipers and derailleur mounting bolts, and the full range up to 8mm for crank arms and larger fasteners. A magnetic holder built into one side plate secures a spare quick link, so you've got a chain repair option without carrying a separate pouch.

Black Anti-Corrosion coating protects the steel bits from the combination of sweat, road salt, and moisture that builds up inside a jersey pocket or seat bag over a season of riding. Corrosion shows up as pitting on bit surfaces, which rounds off hex corners and makes it harder to grip bolt heads securely. The coating adds a barrier between the steel and whatever environment the tool sits in between uses, which matters if you leave it in a bag through winter or ride in wet conditions regularly. The chrome vanadium steel fastening hardware and cast stainless steel chain breaker resist similar corrosion issues at the pivot points.... Read More
