Thanks so much for appreciating my project! It took me quite a while to put everything together, but I’m really happy with the final result. I’m planning to take it to some local dirt jumps soon. I’m also heading to a bike park later this month, so hopefully I’ll finally get to see how it rides!

Apart from the lower ride height resulting from running 27.5-inch wheels, the geometry remains pretty much unchanged.

Fork: Manitou Mezzer Expert — 160 mm, upgraded air chamber to Pro spec
* Rear Shock: FOX GENIUS from Specialized Stumpjumper
* Wheelset: Newmen SL A rims + Ngbut hubs
* Drivetrain: Single speed — Reverse Components conversion + tensioner
* Crankset: SRAM Eagle 90 — 155 mm
* Pedals: Newmen Millennium
* Brakes: Magura MT7 calipers + Chinese aftermarket levers
* Handlebar: BikeYoke BarMate
* Stem: Reverse — 35 mm
* Seatpost: Chinese
* Saddle: Chromag

Total weight: 15,200kg

Wow, congratulations! The bike looks absolutely fantastic. I’m really excited about this build.

Could you answer a couple of questions for me? With this shock length and fork travel, does the head angle actually come out to 63.8°? Also, do you know what shock tune/valving is required to achieve 150 mm of rear travel?

Thanks!

Since this is a 100% custom project, I decided to make a few modifications to the frame. The frame has been completely sandblasted, and some of the components have been satin-finished. I also decided to weld additional reinforcements around the head tube area.
At this point, I’m just about to have the frame painted and assemble the entire bike, as I already have all the parts available.
As for the seatpost insertion depth, it is 117.5 cm

You have a very good idea with changing the head angle using anglesets, and I’m planning to do exactly the same. As for the bottom bracket height, I don’t have any particular concerns because I want to use very short cranks, 145 mm. The only thing I’m wondering about is whether it’s possible to achieve 160 mm of rear travel and 170 mm at the front, so as not to mess up the geometry and to make sure everything works properly.

I finally decided to join this forum because I want to start my journey with a Chinese bike build. I’ve been riding for over 20 years, mostly in more extreme disciplines, and I’ve gone through a wide range of bikes in my life—from pretty bad ones to high-end premium brands.

I’m hoping to find useful information here, as well as share my own experience and an interesting project I’ve just started. I’ve recently ordered a steel frame, and I’m planning to build it into a bikepark-oriented machine. I’ll be happy to share my progress along the way.

Best regards to all members!
