    Internal Transmission

    I saw a GT at Performance today with the internal transmission and was curious if anyone has tried it.
    What's your opinions about this design?

    ...isn't it just an i-drive. I am not 100% sure what you are refering to but I love the idea of internally geared bikes. Especially with the gearboxx standard. If the gearing is centred on the bike and not exclusively on the rear, the bike ends up nicely balanced. I would jump on one if I had the cash

    They are likely using the nexus hub centred in the frame to drive a ss rear wheel in the back (single speed and reversed....)

    Looks decent enough. I have ridden nicolai, which is where gt got the base design, and loved it. very centred and didn't feel tooo bad.

    well I think that internal gearbox will suit for downhill racers but I disagree if they are planning to use it for XC, haha I like the simplicity of a bike looks

    I've ridden one of them on a DH track. It is so weird, you can crank hard into a corner, stop pedalling then shift and it is instant change when you put the power down. However the ratios in the Nexus hub aren't the best for DH, not close enough. Also the angles on that bike just don't suit me for DH and it was quite heavy for what it was, still nice though.

    Why would an internal gearbox be bad for XC?

    if shimano made a heavy duty version of the nexus 8 I would be all over it.
    The GT is cool, especially given their bizarre business history, but 5k seems a little steep for something so new and relatively untested by the consumer market. It would be cool if companies "Xboxed" their high end stuff, and take a little hit off their flagship bikes in hope to generate more buzz over thier entire product line.

    If they could make a lightweight internal shift system for XC I'd be all for it- my big ring has been my Biggest Enemy, in terms of scars and broken/bent teeth on logs and rocks.

    In the next couple of weeks I'm going to go back to performance and test that beast. I'm intrigued on how the gearing will feel. I think this technology is here to stay, well at least in the DH sector and must weight about 40lbs or so. Wasn't this concept originally from Honda? I believe the RN01 is where I first heard about it.

    Well honda in reality tried a CVT system. Internally geared in their world ended up being a deraileur system in a box...literally...(once the CVT was pulled)

    I would imagine roholff was the originator (or one of for biking anyways) Several companies ran wth the idea and have done some impressive things. Nicolai, I think, being the most popular in its implementation.

    I read some stuff saying that the transmission deal just put lots of drag on the bike when you wernt peddling. Is this true or what?

    Haven't heard a thing. I didn't know they were working on anything

    I didn't notice and I am not sure why this would occur. There might be some efficiency lost due to multiple chaining
