Hi all

My first post on here really apart from replying to a couple of classifieds.
Maybe a random thought and maybe in the forum but....

Last night i was thinking...........Has anybody tried running a 29er fork and wheel on the front with the standard 26 on the back. I suppose the theory being that the front will roll over the bigger dips etc etc and all the other up sides of the 29er with the thought that rear wheel will just follow.

Mmmm the things I think about on night shift

    Yes, it's called a 69er

    It would change the geometry, making headangle slacker. Cant think of any reasons why not, but then again can't think of any reason why you would do it.

    On kind of the same note, if 29 is better then why not 29.5 or 30?

    I believe the reverse combination has been tried too. Must be a pain if you like to carry a spare inner tube

    Because 29" wheels already existed, as did 650B. They just chose another conveniently available wheel, and claimed that it was better, rather than trying to actually research into the optimum.

    Many HT's can be 69ered by using a shorter travel fork than the max it willtake to keep the ground to crown distance the same as the max it should be with a 26 wheel.

    A Friend has a 36er (next wheel size up) good fun and like a fatbike will steamroller many a rough surface, a little cumbersome though!

    Surely if you have a bigger front wheel than back wheel you will always be riding uphill. Better that you do it the other way around so you can ride faster.

    There's a lot of stupid stuff on here recently, but despite that, I'm going to give you the benefit of the doubt, and just assume you're joking.

    No no no....the chain would need to be tight, then it would be fine!
