How to Use the MT-10, MT-20, MT-30, and MT-40 Multi-Tools


Today we’re going to look at our multi-tools
– the MT-10, MT-20, MT-30 and MT-40. They feature forged aluminum side plates and hardened and plated tools for smooth and ergonomic operation. The MT-10 features a 3mm and 5mm hex on this side with an 8mm hex adapter for snugging up a loose pedal and on this side features a Torx compatible
T25, a 4mm hex, and our combo tip which works
on flat and Phillips screwdrivers. The MT-20 features all the same bits as the
MT-10 with the addition of a CO2 adapter. Let’s take a look and see how the CO2 adapter
works. Begin by installing the adapter onto the valve
stem – we recommend a threading motion. Next thread the cartridge onto the adapter
until you feel the pin make contact. Then, turn another revolution to puncture
the cartridge. When you’re ready, unscrew the cartridge one
revolution to release the air pressure into the tire. Nice and hard – and then I thread it back in to close it,
and pull it off and lock that tight. The CO2 adapter is optimized for Presta valve stems. If you plan on using our CO2 adapter as an
emergency tool for a Schrader equipped bicycle, we advise pulling out the valve seal using
a seal pick or pliers and flipping it around. This will make for a much more reliable seal
on Schrader valves. The process for using the adapter on Schrader
valves is the same as for Presta valves. The MT-30 features all the bits that the MT-10
has, with an additional 2.5mm hex, an additional 6mm hex,
an additional T30 Torx-style bit, and an 8 & 10 millimeter box end wrench. The MT-40 features all the bits featured on the MT-30, but we’ve replaced the 8 & 10 millimeter box wrench with a ten-speed compatible chain tool. It also features the CO2 cartridge adapter. Let’s take a look and see how the chain tool works. In a trail side situation where your chain
is broken and you don’t have a replacement rivet, you can use your chain tool to remove the
damaged links and rejoin the chain as a short-term fix. Choose the appropriate rivet to drive out and use the chain tool to drive it out just
far enough to detach the damaged segment of chain. be sure not to push the rivet all the way out. Once the damaged chain has been removed, reconnect the other end of the chain and drive the rivet back in. You should consider this a temporary fix –
be sure to replace your chain as soon as possible. If you’re replacing a chain, simply drive
the rivet all the way out to remove the old chain. Be sure the pin is square and fully seated on the rivet. To install the new chain, place a new
connecting rivet into the rivet hole and place the roller into the chain tool.
Drive the replacement rivet into the chain. Finally, break off the pilot tip using the
chain tool. Our new chain is installed. the MT-10, MT-20, MT-30 and MT-40 Multi-Tools
