Haven’t read all the above, so apologies if this is duplication.
I have a 2016 enduro EVO, which started as a 26”, then (after buying new back end) mutated into a 27.5. After the addition of a 29er fork is now a mullet.
I’ve not eaten through shocks at all in 7 years of owning it (still running a CCDB coil).
It’s not especially long, but with the 29er fork, the head angle is a good level of slackness. It sits into its travel as it’s a coil, so a slighty higher BB is no problem.
Al-in-all still a cracking enduro/miniDH bike which I use in the Alps/bike parks etc: it’s not a trail bike for sure, but for nailing lumpy, rooty trails it’s ace.
Only issue is not as much standover as I’d like on the ‘large’ I’m running (to get the reach) so a 125mm dropper is all I can squeeze in.
Mines Alu, so it’s also a big lump, like me.
