3t - Discus C35 Stealth
The Discus C35 Team Stealth wheelset is the mid-range wheelset from the 3T Discus range. 25mm wide all-carbon-fibre rims offer a 20% overall weight saving over the entry 3T Pro model.
Centrelock disc-brake hubs with 24 bladed spokes front and rear offer industry-standard fitment for quality disc-brake setups. The 3T linear+ system optimises build quality and asymmetric rim drilling reduces difference in spoke tension between drive side and non-drive side.
The Discus hubs have a light-alloy oversize spindle with modular end-caps that can be easily swapped from quick-release to thru-axle as needed; rear width can run 135mm or 142mm to fit the latest CX and gravel-grinder thru-axle framesets.
The all-carbon-fibre rim is 32mm deep with a blunt profile for stable aerodynamic performance at typical angles to the wind. A wide tyre bed provides a really firm base to run the latest, race-weight fat tyres at lower pressures.
3T Wheel Technology
Discus wheels have 25mm wide rims that provide an ideal platform for today’s wider-section road and gravel tyres. You can run these wheels at a lower inflation pressure for better rider comfort and endurance with no penalty to speed.
Team Stealth wheels have all-carbon-fibre rims and up-to-date aerodynamic profiles, so you won’t be slowed by wind drag or thrown offline by gusts.
The 3T linear+ system unites the best all-round techniques for building robust, responsive and lightweight wheels which in normal use will give you years of riding pleasure.
Full-Aero Wider Rims
3T Discus wheels have 25mm rims which are the new, wider standard for today’s breed of fatter, lightweight tyres.
A wider rim lets you run the latest race-weight tyres at lower pressure. The tyre’s wider, shorter contact patch with the road surface gives you more grip and comfort than traditional narrow tyres at high inflation pressures.
At the same time, 3T rims are aerodynamically profiled for low drag at typical yaw angles.
This means with Discus wheels you get;
Better handling control
Less rolling resistance
Reduced incidence of punctures
Low and stable wind drag
Linear+ Optimised Build
3T linear+ system optimises all-round build quality. Discus wheels have straight spokes that run directly from hub to nipple. Spoke ends locate perfectly square in the purpose-designed hubs; and at the nipple end, the rim drillings are angled perfectly in line with the spoke.
Nipples are internal, so rim drillings are no wider than needed to pass the spoke through. This benefits strength, appearance, and aerodynamics. Nipples are screwed on upside-down, bearing on the rim’s internal surface via a cup washer. This distributes the load evenly on the rim so spokes can safely be done up tighter.
Compared with traditional wheels built with J–bend spokes, 3T linear+ have;
Better load distribution
Better spoke alignment
The 3T Linear+ system is further enhanced in some models by asymmetric rims.
Front wheels with disc brakes, as well as rear wheels (with or without discs), have off-centre hub flanges. On one side the spokes are at a steeper bracing angle, so they must be tensioned more. The 3T asymmetric rim compensates for this by reducing the difference in bracing angle between the two sides.
Spoke tensioning is more equal to either side, making a better-performing, more resilient wheelset with better lateral stiffness. Linear+ ensures that rim drillings are perfectly aligned to meet these demanding mechanical requirements.
Both the 58mm and 32mm rims have an asymmetric structure and double-angled spoke drillings, for a perfectly balanced wheelset. Additionally, 3T Discus hubs have double-cross spokes on both sides. Opposite spokes on the same side are perpendicular to each another, so directly opposed. This equalises spoke load under torque for better power transfer without spoke wind-up, a key benefit when braking is effected at the hub, as well as when accelerating.
Taken together, these measures result in;
Reduced wheel dish
Reduced L-R spoke-tension difference
Greater lateral strength
Optimal torque transfer
Minimal spoke wind-up when braking and accelerating
Modular Hub Spindles
3T Discus hubs have a light-alloy, oversize spindle with modular end-caps. The modular end-caps allow you to easily change from quick-release to thru-axle, and back again. You can use your 3T wheelset on several bikes of different configurations:
Front: QR 100 mm or TA 15 x 100 mm
Rear: QR 135 mm; TA 135 x 12 mm; TA 142 x 12 mm
Advanced Carbon-Fibre Technology
3T’s mastery of carbon-fibre design and manufacture means production of the most advanced rims in the business.
3T Discus rims are constructed with top-grade carbon-fibre, with proprietary resins custom-formulated for each product.
Manufacture involves high-accuracy lamination and high-pressure, low-temperature, long-cycle curing times. Production flow is traced from raw materials to finished product for end-to-end quality assurance.
As a result, 3T rims have;
Exceptional strength-to-weight ratio
Superb impact resistance
Extended service life
