2025 Texas Chainring Massacre Presented by ShiftLess

Early Bird entrees for Saturday events are FREE for Club Spinistry members until 1/1/25! After that Club Spinistry members save 50%.

Please note, this is now a two day format with the featured A Race (The Privateer Preseason Invitational) rolling on Sunday. 80 mile Saturday riders can use their finishing time to qualify for the Sunday main event if they did not receive an invitation. More details soon.

The fastest 100 miles on gravel is now the fastest 130+ miles of gravel! 10 hour cutoff to log a reference time. As currently mapped on Ride With GPS 133 miles and 6400' of climbing. Routes are subject to change. Do not plan on setting up for a sprint finish. You had better establish your gaps while out on the course. Think of it as a mass start TT. Drafting is allowed, assisting other riders is allowed, neutral water tables and stores will be along the route. Aside from those particulars this should be considered a self supported event. No team vehicles or cached supplies for support allowed. All distances are intended to be fun training rides for every level of experience.

Same general rules apply for the 80ish mile amateur distance and the 50ish mile practice event. 80 and 50 mile routes are awards for bragging rights only but will include age breaks in addition to the overall accolades. Please note that overall rankings for these distances will be excluded from the age based rankings. Age/gender breaks will be determined based on attendance.

"Non competitive" riders are eligible to ride all distances 80 miles or less. Non competitive riders will not receive an official time. Beginner riders are limited to riding just the Beginner distance.

Please note that we have a new host city/venue for this year.  Club membership must be effective on event day for the discount to be available. More details soon.

Entry fee covers a trial membership to Club Spinistry for those who are not current members. A portion of the fee can be applied towards a full membership within 7 days of the completion of this event.
