Absolutely! Please come visit us at the Gulo Wheel House. This is where our team of expert builders assemble and build the best wheels ever made. We are available for drop-ins Monday-Friday, 9 am-4 pm. Or call to schedule your visit.

All Gulo wheels are handbuilt in the Gulo Wheel House, 33 W. Probart St. Brevard, North Carolina, USA.

Fortunately for you, the customer, we keep all the building in-house, ensuring that our wheels are built to the highest standards and meet all QC checks. Because of our proprietary wheel system, it is not possible to mix and match other companies’ parts into your Gulo Wheel System.

Gulo Wheel Systems require the use of Gulo’s own Easy Thread Interface hubs, and thus can only be bought as a complete system.

We are currently working to offer a few bearing upgrade options to our stock Gulo Wheel Systems. In the meantime, if you are dead-set on those fancy ceramic bearings, we will get you set up as a custom option. Just call in and inquire on details & pricing.

Even though the Gulo Wheel System is built on proprietary rims, hubs, and spokes, it is easy to service them with basic shop mechanics tools.  Please refer to our Service Guide for detailed instructions.  So, if you do happen to break a spoke, have no worries.  It is highly recommended that you get your wheel back to the Gulo Wheelhouse where it was born, for a free and full refresh.  If that doesn’t work, we will send you the spoke for free and you can have your favorite mechanic get you rolling again.  If you need more assistance please give us a call or send an email to service@gulocomposites.com

Our GMX-25 wheelset has a recommended weight limit of 220lb. 

Our GRX-SL wheelset has a recommended weight limit of 250lb. 

These are super lightweight, race-ready wheelsets aimed at competition.  They are extremely durable and capable of abuse, but if you’re an Endurbro Huckster or Clydesdale looking to grind gravel on the weekends, we have other great options for you!

Yes, please refer to our warranty program.

Most wheelsets are in the Gulo Store and ready to be ordered and shipped within 2 business days.  If it is listed as “Out of Stock” in our web store, your wheels will be hand built and shipped within 5 business days.

We offer two different styles of rims for different applications. 

Our MTB lineup are all hookless rims.  For high volume/low pressure setups, hookless is the preferred design.  The rims can be made stronger to absorb impacts while still maintaining a secure lock between tire and rim. 

Our Road lineup of wheels is all hooked rims.  These are preferable for high pressure/low volume setups, where impacts are not as common, and tire security is critical.

Yes, all Gulo Wheel systems utilize tubeless ready rims.  You will receive them taped and with tubeless valves installed, ready to mount your tubeless tires and go ride.  You can still use tubes if you prefer.

Currently all Gulo Wheel Systems are disc-only.  As a new emerging company, aimed at the highest end of the cycling market, we want to push cycling and technological trends in a forward direction.  Unless your Dad’s Schwinn LeTour makes an historic comeback, we will continue on this path.

Please make sure when ordering your new Gulo wheels that you select the correct driver body to fit your bike. 

On our road and CX wheels, you can choose between Shimano 10/11spd, SRAM XD-R 11/12spd, or Campagnolo 11spd. 

On our MTB wheels, you can choose between SRAM XD or Shimano Microspline.

We also have axle and end cap kits available to fit most common axle/spacing specs.

We recommend checking your hub bearings regularly for smoothness and bearing play.  If the bearings have developed wear (i.e. pitting, resistance, play) it is easy to replace them.  Please refer to the service page for our hub schematics.  You can also send your wheels to the Gulo Wheelhouse and we’d be happy to service them free of charge, at the cost of the bearing only.

An asymmetric rim profile allows for better triangulation of spoke angles and more balanced tension.  In wider rims, this profile is preferable.  That is why the MTB and CX/Gravel Gulo Wheel Systems utilize an asymmetric rim profile.  In our road rims, where an asymmetric rim offset would not be possible, Gulo has designed the spoke hole drilling to alternate back and forth be 1mm off from the centerline of the rim.  This allows the spoke to enter the rim at a less severe angle and helps with spoke fatigue life.

GMX-25 & GME-30 - 20-40psi recommended

GRX-SL - 130psi Max for Road, 80psi Max for Gravel

GRD-36 & GRA-46 – 130psi max for road, 80psi max for gravel

Only use this as a reference when having a professional mechanic true or service your wheels.

Front disc-brake side: 115 kgf

Rear drive-side: 115 kgf

Store your wheels away from direct sunlight as UV light can discolor and deteriorate resin over time.

Check your wheels for trueness regularly.  A properly trued wheel will not require re-tensioning frequently.  If a wheel becomes out of true and neglected, the balance of the entire system will be affected and may cause further issues.  Wheels should be maintained and trued as soon as it is apparent to the user.

Please only use tire levers as a last resort.  If using proper tire installation technique, you should not need to use tire levers.  If you need to resort to tire levers, ONLY use plastic levers.  NEVER use metal tire levers or other sharp metal objects.
