Has any one ran 26” wheels in a 27.5 frame/fork that done it for a long time.

I’ve noticed a small crack in my nukeproof mega tr frame.

I’m looking at getting it repaired but if I do get another frame 27.5 I’d wanna reuse my good set of mavic 26” hope hub wheels to save a bit of cash and reuse perfectly good parts until I can buy new wheels etc.

Reading stuff online is there really that much difference, I doubt I’d notice it anyway.

Hopefully the bike can be fixed to allow me to save towards another bike or frame etc.

Just thinking about my options.

    Shorter wheelbase, lower BB, maybe compromised geometry, but faster acceleration.

    I'd put some tyres on that inflate bigger than most. The 2.2" Continental Trail Kings on a 26" wheel measure at 27.75". Schwalbe Rapid Robs (2.1") on a 27.5" measure 27.25". So depending upon which tyres, there may indeed be not much in it!

    Erm, wheelbase will stay the same as it measured axle to axle.

    Not much difference in it then.

    I’m running maxxis minion tyres which are a bit chunky 2.35 I think.

    Can’t believe frame has cracked, it’s only about a centimetre on a weld, know people who can weld but no one got a tig welder :(

    Of course it is! Doh! :oops:

    In fact it doesn't matter whether you measure from axle to axle or from where the wheels touch the ground, they are the same.

    I blame rushing to make the post before dashing out. Not enough review time, but what a newbie mistake! :oops:

    any Dartmoor Hornet owners on the forum?

    Looking at this as a replacement frame for the time being and can’t decide on size medium or large.

    I’d be running it 26 to reuse my parts. Does wheel size now also decide frame size? I mean a 29er in medium and large in 27.5 etc or am I talking rubbish here

    Wheel size isn’t directly linked to frame size but you can’t really build an XS 29er due to toe overlap and even an S is marginal which is why some otherwise 29” bike models are 650B for the smallest sizes.

  • if you can find some, 26x2.6-2.8 might fit, giving the same diameter wheel, but more grip.
