Bontrager Line Line 30 TLR

Specs from Trek's own product pages (spec table per front/rear option); this entry combines Trek products 45471, 45472, 58104, 46773, 48778, 48779. Years: first model year found as original equipment on a Trek bike (Roscoe 7 (MY2022)) in Trek's bike archive; still sold on trekbikes.com, so the last year is current. 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). Trek gives only an inner width band for some variants (spec.internal_width_listed). Partial: Trek lists no wheel weights. Price labels fixed 2026-09-27: list_price_usd changed from $98.99 (one front wheel) to $223.98, 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.
