The Mach1 M670 / Combo+ rim
The Mach1 M670 rim is specially designed to offer remarkable strength and durability, which makes it a perfect choice for city electric bikes (e-bikes), for trekking bikes and for MTBs. Its eyeleted double-wall construction optimises spoke tension and can support a total bike system weight of up to 150 kg. With a 21C width, it is compatible with every size of urban and all-road tyre, while also suiting MTBs fitted with tyres of up to 2.2" in section. What is more, its CNC-machined sidewalls guarantee optimal, safe braking, combining reliability and performance.
