I'm looking at some 29er boost Revelations to run with a 29+ wheel on my Trek Stache.
I know that the wheel fits in Revelations with the most recent lower leg casting. When did the latest ones appear, and are the ones in the image below the latest casting?

All the second hand ones I can find are 150mm. Is the airshaft to drop them to 130mm the same as the ones for all Rockshox Pikes, or only the newest ones? If the shaft is specific to the newer models, does anyone have a link/part number as on google they all look the same to me!
Thanks
35mm stanchioned Revs appeared in 2018 iirc.
If your looking to change travel you can upgrade to a 2019 DebonAir air shaft for around £40.
I believe all 35mm airshafts are compatible but check with TFTuned or similar before you take my advice.
They are the 2018 ones, and you'd need one of these to go 130mm: https://www.bird.bike/product/rockshox-air-spring-upgrade-kit-2019-debonair-pike-b1-revelation-a1-2018-27-5-29-130mm/
Excellent, thanks very much for your help gentlemen.
