Don’t look too bad, but as above (depending on what shock it comes with) it’s not going to make much financial sense (does going frame only ever?) when the build kits are so cheap?
It’s been a bit of an eye opener recently window shopping various specs of Bird – to change from an Lyrik fork to 36s for example is a huge leap in money considering on the face of it they’re about the same price in the shop.
Anyway, rambling again – if you’ve got the cash to hand and desperately need to custom spec or reuse your current stuff I’d reckon it would be cheaper to buy comeplely and sell off the bits.
