650B Spinergy GX wheels are a special order item and require an additional 7-10 days for delivery.  Pleas contact us about custom colors and options.

Built for the road less traveled, Spinergy's GX wheels deliver on width, weight, and comfort for a match made in gravel. The 24mm inside-width rims add measurable volume to tubeless gravel tires while the legendary Hadley hubs spin smoothly and engage quickly.  Spinergy's trademark composite PBO spokes damp vibrations, add strength, and help this alloy wheelset achieve the sort of weights rarely seen in anything but carbon.

Let's Talk Tire Pressure:

Click here to listen to a podcast exploring the science of why lower pressures were found to be faster by pro teams.  Just because they feel faster doesn't mean that harder tires are faster- in fact they're generally slower and less efficient.  Silca has a new tire pressure calculator to help you find the sweet spot, but generally speaking 100psi is more than enough for any rider on road. Please do not exceed the maximum pressure stated on your tire.
