BOSCH PERFORMANCE LINE SX MOTOR
It had to happen eventually – Bosch has finally entered the ‘lightweight’ world with the new Performance Line SX system. The new motor looks familiar to us, like a shrunken Performance CX unit with a magnesium casing and two-bolt mount. Weight is a reasonable 2kg – not the lightest on the market, but still competitive with the 1.95kg Fazua and Specialized SL 1.2. It’s the output where it really shines though, pumping out an impressive 600W of peak power, putting it on par with most full-fat options and way ahead of its lightweight rivals. At 55Nm, peak torque is more in line with expectations, meaning it won’t be able to crawl up near-vertical pitches like a full-fat.
