Pumptrack Dream Build – 2021 Kona Shonky

The Build: The Mountain Bike Action crew built up a new Dirt Jumper to take to their local pumptracks. See the complete build, the story behind it and the bike in action all in the action packed video above.

Frame: 2021 Kona Shonky (Short)
Our build began with a Kona Shonky frame which features sliding Thru-Axle dropouts and a threaded bottom bracket.

Fork: Marzocchi Bomber DJ (100mm travel)
The Bomber DJ is a dirt jump specific fork made for 26-inch wheels. It features a 36-millimeter chassis along with an oversized 20-millimeter axle. An adapter kit allows riders the option of a 15-millimeter axle.

Wheels: Industry Nine 305 DJ wheels (Single speed hub)
The most exciting component of our build is the custom set of Industry Nine wheels. We had a pair of 26-inch Enduro 305 rims laced around gold Hydra hubs. To keep the rear end looking neat, we ran a single speed rear hub with a shorter freehub body.

Rear Cog: Endless Bike Co Kick A** Cog (14t)
Endless Bike Cog makes some cool CNC machined cogs and chainrings. We used their 14-tooth Kick Ass Cog on our build. The cog was combined with a 32-tooth front chainring providing a good ratio for dirt jumps, pump tracks, or street riding.

Freehub Spacers: Reverse Components Single Speed Spacer Kit
Reverse Components offers a wide section of parts for riders wanting to convert their bike to a single speed. Our Kona has red Reverse Components spacers along with a red lock-ring.

Tires: Maxxis Ikon (26×2.2”)
Maxxis hooked us up with a set of tires that would have been a cross-country racers dream back in the early 2000s. Maxxis tan-wall Ikon tires are built for speed, but provide additional confidence off-road compared to street-worthy dirt jump tires.

Crankset: Sram GX Eagle (170mm, 32t)
It would have been easy to get carried away with a fancy crank on this bike but at the end of the day, it’s a jump bike built to handle daily abuse. A SRAM GX Eagle crankset seemed like a no brainer.

Chain: Sram GX Eagle 12-speed chain
To ensure maximum chain retention we opted for a SRAM chainring and chain combo.

Handlebar: Burgtec Ride High Josh Bryceland Signature Alloy Handlebar
These 38-millimeter tall bars from Burgtec are a perfect pick for enduro, trail, or dirt jump bikes. We cut ours down from 800-millimeters down to 770-millimeters.

Stem: Burgtec Enduro MK3
A bronze Burgtec stem adds some flair to our ride along with some serious performance. At 42.5-millimeters long with a 35-millimeter clamp area, the MK3 was exactly what this dream bike needed.

Grips: Deity Deity Lockjaw
The Lockjaw grips from Deity offer a super soft and cushy feel that works great without gloves.

Seat Post: Burgtec Xpress Carbon
To keep things light and to add to the bling factor, we placed a carbon fiber seat post from Burgtec on this build. Fun fact, this is the same post the Santa Cruz Syndicate runs on their World Cup Downhill race bikes.

Saddle: Deity Speedtrap
A bronze Deity Speedtrap saddle provides a place to sit when coasting to and from the bike park.
