The Hei Hei's best version

 I got my hei hei cr in 2020 and since then I've changed or modified basically every component, mostly in the search for lightness and more speed on the race course. Sometimes that search went a little too far but for the most part it's trended in generally the right direction. I mean, who doesn't like a lighter mountain bike?






That is just about the best a Hei Hei CR can get, in my opinion. Right about 26lbs flat for an XL, 120mm travel bike on somewhat real tires with pedals and bottle cages and a dropper that works. There are a few things that could make it a touch lighter but some things were chosen due to availability at the time or price or both.

The highlights are that it's a hei hei. DT swiss carbon wheels, X01 axs drivetrain. guide rsc brakes, bikeyoke divine sl 125mm dropper, Industry nine a35 stem with raceface carbon bars, and an assortment of fancy little titanium and carbon bits. I also swapped the standard grip damper in the fox 34sc for a fit 4 which has more control of low speed compression, and then revalved the shock to a firm digressive tune which makes it more responsive while pedaling hard but still pretty smooth over rougher stuff (I think).

The tires are the biggest variable, and depending on what I'm doing they might be something very flimsy like the thunder burts I used for the butte 100, or the minion dhf/aggressor combo I rode for awhile but decided was just a little too heavy and slow for a bike like this. What makes this bike ride the best to me are an aggressive XC or light trail tire. This spring I started out on 2.35 racing ray/ralphs because I had them, and now it's on Vittoria Syerras, which I also rode last fall. The syerras manage to be pretty light and fast while offering better grip and durability than your average XC tire. I also have an insert in the rear tire.

It's basically a bike I can ride just about anywhere, and it'll go pretty fast and be fun while doing it. So now that it's just about perfect I'm considering a new bike of course. 

If anyone wants a list I guess I can do that
