    Rolling resistance of tubulars vs clinchers

    I have a friend who is selling his tubular rear disk/front 404 for a clincher version of the same. He is convinced that clinchers have superior rolling resistance based on a study he found. He thinks he might see a 1-2 min difference in a 40k. Can anyone confirm this? Don't the pros use tubulars...

    Saddleco saddles

    Like most people I've tried a few saddles over the years and have settled for the one that is the least abusive, but last year I bought a Saddleco. I loved it so much I bought one for my time trial bike. There is an outer rim that supports a mesh and your butt rests on the mesh kind of like a...

    More intervals

    I've been doing 4 min intervals times 7 with 4 minutes rest between each as part of my preparation for time trialing. Mostly because of weather and convenience I've been doing them on the computrainer. My more experienced and much faster friend tells me I would get a better workout outside. I...
