I assume that, if the White Eno eccentric hub moves the hub center in a circle around the axle, then it could potentially position the wheel higher or lower rather than just forward or backward. This would require the brake shoes to be adjusted each time the chain is re-tensioned. Also the attitude of the bike changes. The rear fender could be out of position. Am I missing something? Is this a real problem?
Anyone know of another solution for making a fixed gear setup on a bike with vertical dropouts?
