Depends on what you mean by long ride. @nickyboy is team b'twin, he may be able to weigh in on the subject.Are they any good for long rides? Is the chamois good?
Hows the lycra compared to the 500s ?
Took them back as they bobbled on the inner thigh after only a few rides. exchanged and the next pair did the same and found the pad bunched up at the crotch.
Checked the bike and the point of bobbling was not catching on anything , it seemed to me the lycra was very thin and the bobbling turned into a hole , probably worn 2-3 times .
I will have to check them out next time i go in, my old ones with the red pad lasted a fair while but the new ones were a bit rubbish , same goes for the MTB shoes.My old rockrider 5 are the most comfy i ahve had and fit a normal uk size , had to go a eu size up for the new pair and still sent them back as the to box was a lot tighter.I've been wearing the 900 shorts (I assume the bib shorts are the same material) for over a year. No bobbling at all
