Our first batch of Jayhawkers sold out quickly! 

Set up for the new gravel bike wheel "standard" - 100x12TA and 142x12TA. Ships with a set of transformative end caps that allow you to convert the front wheel to 100x15TA (for your suspension fork) or 100x9 Quick Release and the rear wheel to 135x10 Quick Release. We'll even make this change for you in advance of shipping if you let us know your preference. Not sure if this will fit your bike?  Check our cross-reference table or email us at jefe@jefe.bike.

The Jayhawker is named after the abolitionist guerilla fighters that made their name on the gravel roads in Kansas in the 1850s. This strong and capable Dynamo-enabled carbon fiber wheelset is designed for the endurance gravel rider in mind and does double duty as your soon-to-be-favorite bikepacking setup. The Wheelset is designed around me, the 200lbs I carry around, and the 8,000 - 10,000 miles I ride per year on road, gravel, and singletrack. If it works for me, it will most certainly work for you. 

And because I've designed this wheelset for me, I've made sure the hubs come with really great Enduro bearings that will last a long time and are easy to find (even on Amazon!). I've also included two extra spokes per wheel. Why? Because someday--out on the trail or in the workshop--I'm going to need them and I'm not ever going to walk back to town again if I can avoid it.  

The Jayhawker is produced in Taiwan to our specifications by Gigantex, one of the world's largest private label carbon fiber wheel manufacturers. We also made sure that the wheelset is certified to the European Wheel Standard ISO 4210-7--one that requires a brutal 2,000km bench test. Gigantex produces thousands of rims and wheelsets for nearly all of the major Global bicycle brands. We've managed to secure a production slot in between the big names and we're paying forward the favor to our customers!
