The “Life’s Better With Horsepower Brake Reservoir Sock Cover” is 3in x 2.5in. It is the third product in the LBWH product line! This is the same quality as my other second generation reservoir covers, now with higher quality stitching, making the Motonosity logo look better than ever! Let everyone know that everything’s better with a bit more power. Doesn’t matter what you ride or drive! All reservoir covers are made of a high quality terry cloth and look great on every bike, or use it as a wristband!
