    B+ / 29+ N9 (79er)

    My N9 is currently set up B+ as a hardtail.

    Looking at going rigid with a 29+ in the front. Thinking a Niner steel or carbon fork.

    Anybody do some quick calculations to figure how much the geo would change?

    For reference Iím running a DVO Diamond at 130mm.

    B+ / 29+ N9 (79er)

    Iíd google bike geo calculator thereís a good one I use quite a lot (

    It doesnít take into account wheel size but what you can do is take into account the changes in diameter. For example the 29+ wheel diameter would be something like 770 vs a 29er at 740 a 30mm difference so I would alter the fork length by 15mm (half the difference).

    Ride on!
