Front Road/Gravel/Adventure/CX Disc GRM Wheels (25mm internal width)

*2022 - Now available in 700c/29" option*

The GRM is a popular choice for those that want to run bigger tires on their 700c platform bikes. Whether your ride is designed for Road, or Gravel, the GRM's 27.5"/650B size with an internal width of 25mm allows a tire range of 1.6"~2.3" or 40c~60c.

Built the same way we build our mountain wheels, its not afraid of seeing some terrain and air action. Being weight conscious, our rims maximize strength-to-weight by featuring a lean 415g per rim. The GRM is laced with the Shogun hubs, offering high engagement and low maintenance for pure performance and no compromise.


Hand laced in-house with proprietary techniques to ensure no truing or re-tensioning necessary.

This wheelset comes with a set of options for spoke and nipple combinations
D-light / Brass – For optimal balance of strength, durability, and weight, we offer the wheelset with Sapim D-light 2.0-1.6-2.0mm double butted spokes. Paired with the Sapim Poylax brass nipples. Butted spokes are more elastic in its thin section, which migrate stresses on its ends better than straight spokes.
CX-Ray / Brass - For light and weight conscious riders. Best performance in weight-to-strength ratio. This combination is the lightest but still provides a very solid platform for all terrain riding. The CX-Ray spoke is flat-bladed, well known for its flexibility to migrate stresses from its ends, and its aerodynamic. This combination is 52g lighter per wheel, 104g lighter as a whole set.


Nipples - Sapim Polyax

Brass is back as the default option due to popular demand! No fuss brass to end all worries related to corrosion from selant and road salt. With a modern profile, Sapim's Polyax shaped nipples are the perfect choice for high end builds. Alloy Polyax nipples are available upon request (we had no problems with Sapim's 7075-T6 alloy nipples, but brass is 100% guarantee trouble free; and folks say its worth the smallest weight gain) All nipples come in black.


Brake Fitting options
All wheelsets come with standard 6-bolt brake mount. We are sticking to this ISO standard so that we can offer conversion kits to futureproof any of the hubs across all axle spacing standards.

Hand laced wheels

Our wheels are hand laced in Surrey, BC. and we use multiple traditional methods of spoke yielding-stress-relieving, so that when you receive your wheel, you can rest assured that there is no seat in periods, or spokes losing tension in initial rides - these which would require re-tensioning like machine and poorly built wheels.


Premium hand built wheels requiere dedication and take much longer than machine built, but the accuracy and attention to detail produced by the traditional way is one of the key aspects that makes Tairin wheels superior. By choosing Tairin Wheels, rest assured that every wheel has been hand crafted by a master wheel builder, so you get the best quality and labour, at the best deal out there.

We know that purchasing a new wheelset can be overwhelming with all the information at hand. Any questions and inquiry can be addressed by contacting us.
