I have the Tubus Cosmo rack on my hybrid... built with stainless steel to last a lifetime and will support 26 kg | 57.3 lbs (tested with 40 kg )![]()
Have you fitted it on an Alpenchallenge ? Do you have mudguards on it ? If so, how did you attach it to the only screw hole through the mudguard (the rack needs two roundstays) ?
