I like being to put on and remove the fenders as weather conditions dictate.
I'm very impressed by these fenders. They are meant to fit frames with tight clearances. Install was quick and easy - fittment was quicker than with other fenders.
One cool aspect that I wasn't aware of - they remove quickly for putting the bike in a car, etc. And they go right back on without any need to readjust.
The only downside - as with all fenders, they don't go low enough to keep your buddy dry. They are longer than most, but still benefited from an additional buddy flap.
Been using the standard race blades and am happy to finally see an extended version. The extra coverage is great. Could be still a bit longer at the back (never too much), but works well. Installation is simple, and is easy to get on and off. Stays in place and easier to adjust than the standard rubber straps on the regular race blades. Also it is more structurally rigid and don't have problems with wheel rub due to movementdeflection. Once set, they stay where they are even after removal and reinstall which is a breeze with the snap onoff system. The mounting bits left on the bike are not the most attractive, but not bad. Only small issue is some interference with the stationary trainer interface at the rear QR, but no big deal. Primary use is on a dedicated rain road bike where there is no clearance for standard fenders.
