I put a little work in on the bike today. I fit and installed the new Epixon fork. While I was in there, I cleaned and greased the head set bearings. I installed the new bars, shifters, fork lockout, along with my old brake levers and Ergom grips. They were pretty much new so decided to save some money and keep them. It is amazing how much lighter yet more solid these new parts feel!

Before:

Here’s a side by side of the forks. The Epixon feels so much better. Lighter yet more heavy duty.

These tools (including the crown race remover/installer which are not shown) made the install so easy!

Here is the headset mached up.

Handle bars and controls are mounted.

Here is the fork lockout control along with left shifter and brake lever. It came out pretty clean and easy to reach everything.

I always thought I'd like the way the SRAM shifters fit and feel, the way they tuck down out of the way of the brake levers, no gear indicators in the way, perfect for setting up one finger braking. You'll have a lot to consider and a lot of adjustment and tuning to do when you get it back on the ground. All part of the fun
:)
Looks GREAT! Very good components, you should notice a huge difference, and with the front end lightened, it will be a lot easier to pop that front end up and over obstacles.

Did you measure the steerer tube and cut it to where you want it? The bike is should be al you really need as a trail XC bike in its modded state. Excellent.

I cut it using a Kenway cutting tool. It was really simple and made a clean cut. I went a little long so I will have some room to adjust the height of the bars if needed. I don’t think it looks too bad as is. If I decide to cut it down some more it will be a five minute job.

I got my wheels put together today. It’s hard to believe they weigh so much less than stock wheels! I threw on my new seat post and saddle too.

I haven’t weighed it yet. I’ll post the weight when it’s finished. Anyone have a prediction? I’m sure I trimmed at least a little weight down.

Bike’s looking great so far. Great selection of components. My prediction is 34 lbs. What do we win if we’re correct lol?

32.4lbs. or 32.6. Considerable weight has been dropped and it could be lower based on engineers d weights of stock components. This is very interesting indeed.

I got the bottom mounted on my new rear shock. I’m still working on the top. I’m having trouble finding wide enough upper adapters. The bottom has zero lateral play but cycles back and forth as smooth as silk. One step closer.
