I’m just bought a debonair pike to replace my older Yari. The Yari is 140 and the pike is 150, should I be able to just swap air shafts or do I need a debonair specific one?

Every site I look at seems to show different compatibility, some show all models work with one type of shaft and others seem to differentiate between models and years

Help!

This confused me. I had a spare 120mm 29 solo air shaft. When I removed the 150mm from a newer debonair revelation, I noticed the 120 was only 15mm shorter than the 150. So the issue will be whether the solo air shaft is the length you want. For me it worked out well, as the 120mm shaft gives the fork 135mm travel, and I was after 130mm.

Pretty sure the pike/revelation one differs from the yari/lyrik one, stanchion thickness wise.

Yep as above, there different. Assuming it’s a new (2018+ pike) if you want 140mm on the pike then I believe you’ll need:

00.4019.931.002 AIR SPRING UPGRADE KIT – DEBONAIR 140mm (INCLUDES DEBONAIR ASSEMBLY, SEALHEAD) – PIKE B1+/REVELATION A1+ (2018+)
