We say... Tall stack stems mean you can have that nice high handlebar position (good for the shredding and for the spine) without all of the stackers. These are light and beautiful. They say... For when you want to have your bars a bit higher but don't want a big stack of spacers under your stem.. The Laing is a *high-rise* stem crafted from 3Al 2.4V grade Titanium. Equivalent to adding approximately 50mm of spacers under a normal stem, the total stack height of the Laing stem is 90mm. We now offer these in extensions of 50, 70, 90 or 110mm - all have a 0° angle. 1 1/8" steerer clamp size, 31.8mm bar clamp size. 175g in 70mm length. N.B. stem requires a minimum of 50mm steerer engagement - less than this is not safe! Spec 70mm 80mm 90mm 110mm 12 degree angle 1/18 31.8 bar clamp size.
