Inertia Project FOX 40 Crown
Up on the chopping block this week we’ve got some Inertia Project crowns by Function Bikes. Available in a few variations, the Inertia crowns offer some benefits over stock crowns. They make crowns that fit the Marzocchi 888 as well as the FOX 40. Inside we take a look at the FOX 40 kit.

The Inertia Project crowns are 100% US made in Portland, Oregon. They are available in two versions; a half kit and a full kit. Both kits Function says will fit all FOX 40’s (R & RC2).
- FOX 40 Upper Kit (upper crown, direct mount stem, and top cap)
- FOX 40 Full Kit (upper crown, direct mount stem, top cap, lower crown, steerer tube)
Parts are CNC machined from 6061-T6 and have a very nice finish to them.

The main crown plates have a nice black anodized finish to them.

The stem fits 31.8mm bars and has two mounting options available to it, 45mm, or 55mm.
Steerer tube’s inner wall is thicker than most (click to enlarge)

Price:
Each kit Function Bikes produces is priced very competitively compared to other high end crown or even stem options. Inertia believes in giving you a high quality product without the high price.
- $114.95 - FOX 40 upper crown kit
- $189.95 - FOX 40 full crown kit
Weight:
According to Function, their crowns are a good bit lighter than the stock FOX 40 ones. We’ll get up a full comparison in the full article.

I have one of these on my 40 RC2 and it is awesome. A lot cheaper than Risse and looks better
