I just bought a 2015 Trek 520 disc (54 inch frame) and I am in the process of outfitting it with racks and fenders. I am looking at Tubus for racks since they seem to have the best overall reviews. I have two questions.

1. Tubus makes a rear rack for disc brakes which I know will work but has anyone tried mounting the other racks Tubus makes for the rear? The Tubus Disco has a peak weight capacity of 44 lbs. I don't want to overload my bike with weight but I would like the option of going heavier if I need too.

2. With Tubus model racks and the 520 Trek 520 Disc what fenders will work and do brands you recommend? Planet bike seems to be the better option but I welcome other ideas.

Thanks
