The 2019 NOBL TR38wheel set represents the pinnacle of mountain bike wheel manufacturing.


At the heart of this wheelset is the completely silent U.S. manufactured Onyx Racing hubset.

Onyx racing hubs liberate your bike wheels and transform your ride.

Onyx hubs transfer power from your pedals to your rear bike wheel instantly for faster acceleration and more control.

The patented sprag clutch design removes the play and clickety??"clack of pawls against teeth in the rear hub to silence your coasting.

Increase your control on technical climbs with sprags that ramp up with torque to smoothly apply driving force, and instant engagement with absolutely zero lag.

Available in a whole raft of colour options.

Podium Seeker.
For 2019 Nobl have taken their previous TR38 and leveled it up! Aimed squarely at enduro riders, shuttle junkies and those who push their equipment to the limit, the new TR38 is designed for you. First of all the profile has been tweaked. The slightly shallower profile will bring in some compliance while maintaining the strength and durability you have come to expect from the TR38. Secondly, resin system revisions decrease brittleness and once again improve impact resistance. Lastly, our new manufacturing process results in a raw finish that produces a higher level of scratch resistance. Right at home on bikes with 150-170mm of travel, the new TR38 will conquer anything you throw at it.

Oversized 3.5mm hookless lips

Tubeless and Hookless

NOBL rims are produced to a high standard using Toray T700 carbon fiber. We use a hookless design which is lower and rounder than most rims which provides more impact protection and increased resistance to flatting. A curved bead seat helps set up your tires tubeless and makes them harder to burp. Typically a floor pump is all that is needed to seat the tires.


Selecting the right hubs, spokes and nipples are integral in creating the perfect ride experience. Based on your ride style and needs we can create a wheel that offers exactly what you need in terms of stiffness, handling and compliance.


We build all of our 27.5" wheels 3-cross and our 29" are built 2-cross by default. Our standard builds are all 32h as we find the higher spoke count is only marginally heavier than 28h due to the lighter rim weight and 32h builds are more reliable. We find these combinations to be best for most riders, but we can do custom lacing to fine tune wheel stiffness for discerning riders, just ask.


Spoke and nipple combinations available:

Sapim Race - 2/1.8/2 - Race spokes are double butted and are used for the strongest and stiffest wheel builds. Handles abrasion from trail debris. Weight (64 pcs x 260 mm) 363 g

Sapim D-Light - 2/1.65/2 - Light, strong, economical. The D-Lights are double butted and are the best choice for most riders. Does not stretch and twist poorly like 2/1.5/2mm spokes. More elastic and lighter than Race spokes. Weight: (64 pcs x 260 mm) 307 g

Sapim CX-Ray - 2/2.3/0.9/2 - The lightest and most resilient mountain bike spokes available. CX Rays are bladed so they have aerodynamic properties and have the best results in fatigue testing of any spoke. Strong enough for competitive use. Weight: (64 pcs x 260 mm) 272 g


2.0mm Sapim brass - great durability and strength - brass colour only
2.0mm Sapim/DT Swiss Silver Alloy nipple - for ultimate in low weight. Not as good long term durability or strength compared to brass and prone to corrosion in long-term so consider replacing every 2/3 seasons.
2.0mm Black DT Swiss Brass - Black coated brass nipples - top performance and looks - bear in mind brass doesn't take coatings well so can look a little worn after building due to surface contact with spoke keys.
2.0mm DT Swiss Squorx Prolock - brass for ultimate strength and durability - extended spoke head with spline fitting on inside of rim for increased strength and ease of truing with special tool. Bear in mind brass doesn't take coatings well so can look a little worn after building due to surface contact with spoke keys.

Sapim Double Square Alloy - Our wheelbuildes favourite - a top quality alloy nipple with great durability and increased length of head for strength and ease of truing. Removal of rounded or broken nipples is easier too using internal spoke head.

NOBL crowns are available in Red, Orange, Yellow, Green, Blue, Turquoise, Pink, and Purple for those wanting to add some extra colour to their rims. These are vinyl die-cuts and are simple to apply, they can be added at the checkout
