Death traps or a good fix/bodge? I've a new Yari fork to go in place of my Pike on my Reign, the old fork was 15X100 and the new one is 15X110 boost. Ideally I don't want to purchase a new wheel but if there any horror stories then I might just do so. I'm mostly road riding these days and this bike is irregularly used. It is for bigger days out, Fort William and uplifts and the like, though days of gnar are past.
edit, its a 200 odd mm front disc and 6 bolt if it makes any odds.
I've used a problem solver front kit to fit a non-boost hope pro 4 into a boost pike. It fitted well, no issues, and didn't stand out in use. I can imagine it being a bit of a faff if you remove the wheel regularly as the spacers just sit loosely in the drop outs and don't fit in the wheel like the proper hope kit does, but it it's a fit and forget solution you're after, they work very well.
/shameless plug/ You can buy mine for £15 quid if you like, drop me a PM if interested. /end shameless plug/
If you can't get proper conversion end caps for your hub and are relying on spacer type set up it depends on your faith in your axle's strength, with a boost hub or proper conversion kits the end caps are resting in the dropouts so the axle isn't taking 100% of the strain, if the axle breaks the tyre won't instantly hit the fork arch but could if using spacer adapters, that's just my humble opinion, a lot people will say its fine, but I doubt any warranties will be honoured if using spacer type adapters, trail riding should be okay but for big drop-offs n jumps I wouldn't feel safe with spacers.
I have used both the Hope-specific end caps and the shimmy adapters, both work well. Using the end caps, available for many makes of hub, means you need to re-dish the wheel, but get a stronger wheel (more equal spoke lengths). The adapters mean you need to space the disc over (normally included in the kit - so it very much does matter that you have a 6-bolt disc, adapters for spline hubs exist but look a bit dodgy and require switching to a 6-bolt disc). Strong tape around the end cap + adapter makes putting the wheel in less of a faff, plus prevents losing the spacers. Get ones in a bright colour that isn't green so you stand a chance of finding one you lose it on the trail. Blue is good, apart from in bluebell season.
@robo89 I think you are being a bit over-cautious there. Has anyone experienced 15mm through-axle snappage? I am trying to envisage the mode of failure and what would happen, not succesfully.
@robo89 I've been using shim spacers on a 20mm Aireal hub for 15 years now. They're fine.
Thanks all, I've ordered a Mt Zoom one and I'll give it the once over when installed.

Absolutely over cautious. Any non torque cap wheel in a torque cap fork fits just like this. RS/Sram don't seem to think it's a death risk.
The "real" adapters are at best proper interference fit, or, often o rings. They're not weight bearing they're there to space the wheel correctly in the dropouts, nothing more.*
Tighten your axle properly and the additional risk of spacers vs adapters is probably about the same as that of carrying a golf umbrella vs a normal one in manhattan in a thunderstorm.
*well they cover bearings, etc but that's not the point.
