Morning, I just joined this site and cantc seem to find anything about maddux rd2.0 wheels. Just purchased a Cannondale Synapse 105 disc with them. I find that they roll very slow and sluggish. Put 1000kms on them and the rear wheel is clicking/grinding. Possibly a spoke issue and in the shop now. That being said, I'm looking to upgrade the wheelset and need advice please. I'm 6'3" 220lbs. Cycle alot of hills and multi century and day rides. Thanks for your help.
