I don’t need any but run these on a couple of our bikes and prefer them to Fox

Crikey. This might push me into a little mullet project.

Are the different debonair springs for travel change cross compatible between 27.5″ and 29″ forks?

The air springs are cross-compatible across all the A1, B1, C1 Lyrik’s since 2016 until 2022 and Yaris too. Doesn’t matter if Lyrik is boost or non-boost, the spring will still work. Travel is the same whether you fit the spring in a 29er or a 27.5. The wheel size difference is in the casting of the lowers. The offset difference is in the CSU.

Good forks. Luckily I already have one. I much prefer it to the 36 it replaced.

Insane price of £477 if you want 27.5 170mm in red, which I already own, even if you need to buy another debonair spring of different travel it’s still a bargain price, then just sell the 170 spring on here. Ends 1st sept though.

If only 37mm offset.

Ditto the 29 in black…

The wheel size difference is in the casting of the lowers.

Does this mean conversion from one to the other is just a lowers swap?

I have a pr for sale in the classified if anybody missed out
