Wabi Thunder

Frame Size: 49cm
Color: Obsidian Black
Sale price$1,050.00


The Wabi Thunder is a versatile build that can go urban or cross/gravel.  Using our Thunder frameset and CX/Urban wheelset, it takes wide tires (up to 44mm), lots of fender/rack options and a serious beating--all at just over 20 lbs. 

Check here for our latest estimated turnaround time for builds. Timing can vary based on our backlog of orders. See link for more info. 

The new colors will be Obsidian Black, a glossy black, and Glass Graya medium warm gray with a hint of green. Custom colors are also available (see HERE for more info).

This updated frame now has removable cantilever brake posts. This provides a cleaner look when running brakeless/front brake only and allows replacement if necessary down the line.  

Sorry, we are not offering the 60cm version at this time. It will return in Summer of 2024.

NOTE: We are currently limited on our stock crank arm inventory due to supply chain issues. Therefore, we are offering great deals on crank arm upgrades under the "Upgrade Options: Crankset" dropdown menu. If you choose to go with a stock crankset, we may need to offer a branded alternative.


At just over 20 pounds, the Wabi Thunder is one of the lightest all-steel fixed gear bikes that can accommodate wide tires. And it’s all thanks to Reynolds 725 Chromoly steel. As a double-butted tubing, Reynolds 725 has thinner walls throughout its length while its critical connection points are thicker to allow for stronger welds. It’s also heat-treated for greater durability and rigidity than the more-common 4130 Chromoly steel used in lower-end framesets. TIG welded by hand, this frame is as strong as it is sleek.


Our builds feature rock-solid components that bring together the quality, performance and minimalist aesthetic that you expect from Wabi.

Components are curated to ensure light weight and clean lines while not sacrificing performance - or breaking the bank. We source direct from well-regarded brands like Andel, Tektro and Tange - all in our no-logo approach.
