If you’re looking for a proven stem that looks more costly than it is, then this neat piece from Kore is well worth considering.
The smooth forged 2014 alloy back end uses a large thin-wall bore that continues right through for maximum overlap with the front clamp.
This uses a diagonal cut (slots are at 11 and 5 o’clock rather than the normal 12 and 6 o’clock) and unique jigsaw interlock on the top lip of the twin-bolt front plate for a secure feeling and creak-free hold.
The stem clamps to the steerer with a single 6mm Allen bolt and takes an oversize (31.8mm) handlebar. It's plenty stiff enough to cope with wide-handlebar out-of-the-saddle climbs and we've not had any case for complaint yet.
With a shallow five-degree rise it's the ideal shape to get a low, race-friendly position when all you want to see is the trail and the finish line, rather than the surrounding views.
At just 134g (for our 100mm model) and with 10mm spacing from 80-130mm it’s an obvious choice for length- and weight-fussy riders. The polycarbonate logo plug and polished silver and all-white options increase pimp appeal too.
