    Our Prototype Ratcheting CVT

    Fun to see interest in the CVT. The best video is from the fellas at pinkbike.com. All the work that was done is covered in my thesis, except that one patent was awarded, and a second is applied for. I am working on graduating, and would love to get into the bike biz. Have to see how the...

    the gearbox thread

    im boggled. they claim 1.5kg with 8 speeds. It looks like a spur gear box like the suntour or chain style like the new G-boxx, but its SO SMALL! How do they handle the torque?

    carbon gurus, female mold construction?

    I think I can visualize what you are saying. If I got it right, you have a good point. ONe question I have though, is if you mold an additional piece to reinforce the seam, how do you control both the outer surface for finish, and in addition, the surface that will be bonded to the frame...

    carbon gurus, female mold construction?

    physical work ont he CVT has paused since Interbike as I catch up on other obligations I had to put off to get ready for the show. In the meantime though we have been developing some new ideas to improve the CVT and on a 10 speed gearbox as well.

    carbon gurus, female mold construction?

    Thats true, and the main reason I went with the female mold. I looked at prepregs too, but moved away from them because of several reasons. At the time they were difficult to get in small quantities due to the carbon shortage, they must be stored in a freezer, and cured at an elevated...

    carbon gurus, female mold construction?

    yeah, there are several layers on teh outside of the seam. These were cured just like the layers in the mold, with peel ply, bleeder cloth, release ply, and breather cloth inside a vacuum bag. The surface finish is not as nice because of the fabric edges, the peel ply, and the vacuum bag and...

    carbon gurus, female mold construction?

    Thats correct, I used two female mold halves, with a double lap joint in between. The gussets go inside the halves to support the inside walls of the head tube and downtube. Obviously strength of the joints is a huge concern, and why much time is spent on eliminating joints, ie, closed molding...

    funky new lahar (carbon exoticness)

    I believe they designed that rear triangle to flex, particularly the chainstay, as there is no pivot at the rear wheel. Sorta like the ibis softail, or the old gary fisher sugars.

    Our Prototype Ratcheting CVT

    as an excerpt from the gearbox thread: A couple of us here, miket and others, have been working on a ratcheting CVT. Our first fully functional prototype was finished last week. It has a gear ratio from 1 to 3, and should have a completely uniform output (although we havent hooked up a DAQ...

    5-10 hightops

    i'm wearing the high tops right now. I got them for the additional ankle support over the low-tops. The seem to pick up dirt too, but not as much as my vans used to. Great shoes

    why no derailleur hanger standard?

    Some frames though are quite similar, such as MikeT's IH and my Kona are nearly identical except for a small difference in the pocket cutout for the frame. While all frames wouldnt necessarily need to use a standard, such as those trying to accomplish a unique design, it would be nice if there...
