Bontrager Line Line 40 Boost 141

Specs from Trek's own product pages (spec table per front/rear option). List price is the front plus rear sum of the regular single-wheel prices on trekbikes.com (2026-09), the cheapest front and rear of one size (the same figure as front_plus_rear_list_usd). Axle notes: Trek lists a thru axle, 110 mm hub width and a 5 mm axle diameter, which conflict; axle left open; Boost141 quick release rear (141 mm, no enum value). Trek gives only an inner width band for some variants (spec.internal_width_listed). Partial: first model year not published by Trek for this product; Trek lists no wheel weights. Price labels fixed 2026-09-27: list_price_usd changed from $189.99 (one front wheel) to $399.98, the front plus rear sum, and price_basis from each to pair, because the maker sells this model only as single front and rear wheels.
