Breaking up my previous bike to reconsolidate the better bits and sell off the rest. I've noticed that everything seems to be boost these days? Are 142mm wheels out of date now? My Pike is 100mm non boost too. Is anyone speccing non boost, or are they going the way of 135mm qr? 

I hate new standards.

To all intents and purposes, for MTB, yeah it is, has been for a few years now.

Common amongst road and gravel though. And spares are available, just no ones doing new frames with it as, err, standard. lol. 

My next MTB frame will be custom with 142mm, but only as I want to preserve a wheelset that’s worth way more than anyone will pay for it.

STD on road and gravel bikes so alive, well and selling more than MTB boost given the popularity of the gravel scene. Plus with an encap change you can convert to 135 and fit to your retro MTB which you can't with boost

Surely makes more sense to just swap out the hubs? 

For selling non boost stuff, Retrobike is usually a decent bet. Normally people looking for decent parts to keep mid-retro frames going. The post 98 section has it’s own classifieds.

There is still reasonable demand for decent non-boost bits secondhand.

Hard to find new though (apart from gravel stuff), as boost has largely been the consistent standard for nigh on 10 years.

The Wheels are Hope Evo Pro2s so can be converted to anything you like. not sure if theyre worth converting and keeping in place of the superstar Novatechs i got cheap for the hard tail. New bike has Hunts, which i know nothing about, so no idea if they are any good inside., or if they will be as easy to maintain as hopes.

Dead as a doornail but exactly as good as they were, and nothing of any value has really changed. Especially nothing stopping you from reusing, my bike are a mix of boost and old-standards-plus-adaptors and just old-standards and other than an occasionally annoying "I could fix this with THAT wheel but I'd need to redish it" it's never an issue.

If you just want rid, I suspect the best thing to do is to get a cheap frame and build a bike, aim the price right and nobody cares that much about standards. But it's getting to the point where there's just not all that much old-standard stuff for sale which really makes it hard to judge what it's worth.

Is that the DJ Pike or is it just a normal one with a really short air spring?

They’re Chris King, so will last forever and replacing them like for like will be, near as makes no difference, a grand. For an extra 6mm. Plus they’re attached to 27.5”  rims, so no need for the extra triangulation.

As above, they’re ace wheels, that haven’t got worse because others have arrived.

I doubt that it is dead, just outdated in the new-bike ecosystem

I'm planning just to re-home my Hope Pro 2's onto some new rims for my gravel bike, just need to fit a pair of 12mm end caps to the front (because road/gravel using 15x100 instead of going to 12x100 would have been too easy!).

I've actually been using them on the existing Enduro 27.5" rims in that same same setup, but they have the double-whammy of being both heavy and narrow for that purpose (but still perfectly functional, obviously).

On a tangent, I've got a new fork for my bike - apart from the difficulty of finding a 100mm fork, I've used the MRP boost adaptors to convert a 100 mm Pro2 - this is working well and was zero faff, will carry on until I can justify a new wheel.

Definitely not dead in my world, given up trying to keep up with modern standards, 100x15 & 135qr till I die*

* Not actually true coz I'll have to buy an ebike at some point 😞

I don't think its worth worrying too nuch about  standards .There'll always be a work around.. The more the industry changes up the standards the more they diminish the notion of standards in the first place.

The onward march of technology definitely has its benefits. 

 

My gravel bike runs a pair of 142/100mm XTR Hubs, with a Titanium Freehub, that I bought un-used and unopened on eBay for about forty quid. They are lovely, but unfashionably narrow for an MTB!
