    New Spawn 24/26" Convertable Bike with growing chainstay and BB adjustment

    This looks interesting. I'm sure the devils in the details here. Seems like a lot of these "Grow" bikes are really just 26" frames with 26" suspension. Flow was really close to getting something special I think. We'll see what this looks like.

    Where did flow ever get with those 20/24 & 24/26 FS bikes?

    Unless there is more to it than a flip chip for the rear end, you're going to have a dramatically different bike when you convert - lowering the BB enough to compensate for a 1" larger radius wheel just by moving the rear axle upwards is going to cause you to have a head angle several degrees slacker. Maybe you can adjust the travel on the fork as well?

    The big issue with all of the conversion ideas I've ever seen (and I've thought about building some myself) is that by the time the kid is big enough for the next wheel size up, they really need a longer cockpit/reach/front center as well. You can just slap a longer stem on, but that's far from ideal.

    Photos are often deceiving, but the stack looks huge. Definitely curious to find out more details. But, I'm kinda committed to the Clash 24 now regardless. There's also a decent chance that when the time comes I'll just skip 26 altogether and go straight to 27.5.

    I was wondering about this. My sons buddy's little brother has a Rocky Mtn Reaper 24 and it looks pretty long and slack. Just can't escape the long chainstays in the 24" size even with a flip chip.

    And when you convert to 26, the reach shrinks somewhat significantly.
