Love(d) my bright orange Conti training tire on my CT. Smooth, no daily cleaning of rollers, put on 1000 miles last winter and 200 this year, until a surprise - wap - wap - wap - BAM, side wall blew out. LBS was wow'ed ! A new superman on the trainer? ( not ). Their sending it back to Conti for a swap out, meanwhile back to an old black Michelin left over. Lumpy, slips, have to clean after every CT ride. I'll go for another orange conti trainer tire, even with an occassional heart stopping side wall blowout.
