Here’s a look at the updated version of Chris Doyle’s signature stem from Demolition. The 6061 alloy Keystone V2 top load stem has an all new CNC logo, 32mm stack height and a reach of 53mm. They’ve slimmed this version down to save some weight, which the stem now comes in at 9.5 oz. The stem is available in black, blue, red, polished and purple. Check out more photos here.
