M-Wave IS42 / 52 C Aheadset

Order via Sprocket&Gear was smooth, and headset arrived in good time.
Headset (Integrated) was complete, and fitted well. I note that it doesnt have an additional seal on the lower bearing (which others such as Hope do), so although bearing race itself is well sealed, the gap between the bearing underside and the fork crown race seems a bit unprotected, so time will tell on how long this resists rain and mud. It is however, well under half the price of many others, so all in, not a bad buy.
