Bontrager has launched its new range of Line 30 carbon-fibre mountain bike wheels.
Although these new wheels have an internal rim width of 29mm, the naming convention has rounded-up to ‘30’, with the range tallying both Line Pro 30 and Line Elite 30 product grades.
The Trek sub-brand has redesigned its mountain bike wheels to offer superior pinch flat resistance. Bontrager’s solution regarding pinch flats is to widen the rim’s hook wall thickness and bead radius.
Reshaping the rim profile has enabled Bontrager to increase the hook bead surface area by 300%. The result is superior dispersion of impact loads when terrain forces create momentary crush contact between rim bead and tyre.
Beyond the reduced pinch flat properties, the new Bontrager Line wheelsets also feature a shallower 27mm rim depth which delivers improved vertical compliance, promising better ride quality.
Anchoring the new Bontrager Line 30 wheels are Rapid Drive 108 hubs. True to their name, these hubs have an impressive 108 points of engagement. On each hub, two sets of three pawls interface with a 54T drive ring to allow for a mere 3.3-degrees between engagement.

Bontrager has structured the new Line 30 wheelset range in two variants, Pro and Elite, offering both 27.5- and 29-inch wheel size options.
The Line 30 Pro wheels are dearer and lighter, at 1710g and 1760g a set for the respective 27.5- and 29-inch sizes. They are priced at $1,299.99, irrespective of wheel size.
For riders who desire a carbon wheelset and can deal with slightly more mass in the rim, possibly preferring the security of those extra grams in composite material, the Line 30 Elite derivatives are 1,820g and 1,890g for wheelset sizes 27.5- and 29-inch. These slightly heavier Line 30 Elite wheelsets retail at $899.99.
All Bontrager Line 30 wheelsets are built with 28-spokes per wheel and the hubs feature six-bolt disc brake mounts.
