not sure if this is helpful info but…
I ran a maxle on my 2008 meta VIP – real cycles sorted me out with a the drop outs + maxle.
Then had a hub axle snap (not the maxle) and then the swingarm developed a few cracks too…
I sold the maxle kit and sticking with QRs now. My thinking is that the maxle can’t have added much stiffness given where the swing arm was cracking.
Still love the bike! Realcycles sorted me out with an old meta SX swingarm (had to saw off the seat post stub to fit this but hey…) and that’s what I’m riding now. Prefer the look of it tbh.
