Magura Marta SL Magnesium disc brake review£260.00

Marta gets the diet treatment

BikeRadar score3/5

Light but still with plenty of power and reliability, the Mag SL is an impressive – if expensive – all-rounder.

By switching to magnesium for the master cylinder and adding a carbon fibre lever, Magura save 43g over the standard Marta, and the skeletal 129g 180mm SL rotor makes this version more competitive.

A closed clamp makes fitting to carbon bars a gentle job, though, and the hoses are ridiculously long. Carefully bedding in the pads is essential to get a good lifespan out of them, but otherwise we’ve had trouble-free years with our Magura anchors, and there’s a five-year leak guarantee too.

The very sharp, firm lever feel that’s characteristic of most Magura brakes won’t suit those who like more of a squeezy feel. Modulation and power are consistent and adequate for most situations though. There’s also an alloy centred Ventidisc rotor option for mountain use, but at 213g it adds a lot of weight to the system.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
