We have carbon rigid Boost 110 front forks in 29+ which we sell for $420 apiece. We get these with our Boost hardtail frames, but since many of those customers have us build with a suspension fork, we have some extra forks that we do sell. They are tapered steerer tubes, 500mm A2C, 51mm offset, and include the QR thru-axles which are 15x110.
Sorry, we are sold out of the 27.5+ version.
29+ fork: 740g including axle
But here's the deal: these forks are great and we have never had one fail, but if you're planning on catching big air and riding this fork like a suspension fork on your mountain bike, we don't want you to break your face and sue us. So any buyer/rider of this fork must sign our waiver (shown below) releasing us from any possible legal claims. This is not a suspension fork -- don't go catching massive air on it and get hurt, please!
