Description

New colours for the Speedco M2 Alloy Youth frames bring a fresh update and confirm that the V-brake is not quite dead, yet! The Speedco M2 youth series retains the brake post mounts on the seat stay, though you have the option to run disc brakes using the M2 adapter.

Reliable 7005 series aluminium is used to manufacture the Speedco youth series of frames, tubing that is heat treated and double butted for weight reduction and increased strength. The down tube is tapered and wider at the bottom bracket to provide increased stiffness in this critical area. Bottom line, these are super light aluminium frames.

Additional features of the M2 frames include a seamless integrated chain tensioner system and internal cable routing from front of top-tube to mid seat-stay exiting right at the brake caliper, keeping the hydraulic hose protected as possible.

If you are making the jump to your first disc brake frame? Contact LUX's customer service team and they will step you through the process to ensure that everything goes together smoothly. They can help you choose the right wheelset and disc brake set up for your new Speedco race rig.

Features

Junior Cruiser, 18.75" top tube. One of six youth sizes in the M2 range, running from a 17" Mini up to a 20" Expert Cruiser.
Double butted 7005 aluminium. Heat treated tubing keeps these youth frames light, with a tapered down tube that widens at the bottom bracket for stiffness.
Rim brake now, disc later. The seat stay keeps its brake posts, and you can move across to disc when you are ready using the Speedco M2 adapter.
Euro bottom bracket. A standard Euro shell keeps bottom bracket and crank choices simple when it comes time to replace them.
Internal routing, integrated tensioner. The hose runs inside from the front of the top tube out at the calliper, and chain tension is built into the frame.
