Bontrager presents two new MTB wheels: the Line Pro 30 Carbon and Line Comp 30 Alloy. According to the manufacturer, both models have been redeveloped from the rim upwards. The wheels are aimed at trail riders and promise improved stiffness, more precise handling and high durability.
The central element of the new development is the shallower 23.5 mm rim depth. In the Line Pro 30 Carbon version, this design is said to allow 13 per cent more vertical flex on the front wheel and 11 per cent on the rear wheel compared to the previous models. The increased compliance promises better absorption of shocks and vibrations, which should improve the riding experience and reduce rider fatigue.
Carbon design with FEA analysis
Despite the lower profile, the strength remains unaffected according to the manufacturer. Bontrager used finite element analysis to model material stresses and failure points. Specific zones have been reinforced to ensure long-term durability and impact resistance even under aggressive riding conditions.
The reinforcements are designed to stabilise critical areas of the rim without adding unnecessary weight. The carbon construction promises a balance between lightweight construction and durability.
Offset spoke bed for more rigidity
An offset spoke bed improves the spoke angles and is intended to offer increased lateral stiffness as well as clearer and more direct handling. This design is particularly effective under high loads when cornering.
The spoke arrangement promises more even force distribution and smoother running. The offset design is intended to increase the torsional rigidity of the entire wheel in both the carbon and aluminium wheels without compromising vertical elasticity. Both models therefore use the identical spoke bed geometry for comparable riding characteristics.
TLR system and tubeless features
The wheels feature reinforced hook walls to reduce punctures. An updated tubeless-ready rim bed is designed to simplify tyre mounting and positioning for Bontrager tyres and other MTB tyre brands. Compatibility with Bontrager's TLR system includes tubeless rim tape, valves and sealant.
Both wheel variants are supplied with TLR rim strips and valves. The system promises faster and more reliable tubeless installation. The rim bed design is intended to enable even tyre seating and reduced air loss.
Line Pro 30 Carbon vs Line Comp 30 Alloy
The Line Pro 30 Carbon is designed to offer a balance between strength and flexibility, promising more control and power transfer. The carbon material enables specific component properties through variable fibre orientation. The weight saving compared to aluminium remains an additional advantage of the carbon construction.
In return, the aluminium wheel: the Line Comp 30 Alloy brings the same trail-oriented design to a more budget-friendly version. The aluminium model promises a durable, versatile wheel for various areas of use. Despite the cheaper material, the alloy version uses the same rim geometry and spoke bed construction as its carbon counterpart. Both models are available now.
