Here are some pictures illustrating how we mount Maguras on the B20 bike using the evolution mounts. We know that the ordinary way is to have the elbows facing up, but by facing them down it also works. Notice how much clearance we have between the tire and the elbow.

We are coming out with a 4 bolt booster that will allow one to use the 4 bolt Maguras on our frames, eliminating the evolution mounts. We apologize for any inconvenience and appreciate your understanding.
