VeloWeight helps road cyclists estimate complete bike build weight using real component data for framesets, wheels, groupsets, tyres, tubes, saddles, pedals, cockpits and bottle cages. Select your parts, add custom components if needed, and get a live total in grams and kilograms.
Total weight and build completion.
Headset, Topcap, Bolts, Derailleur Hanger, Cables, Brake Fluid and Bar Tape Estimate: 325g
Add anything missing from the component list. Custom components are added to the current build total and export, but they are only saved for this build.

VeloWeight uses a mix of official manufacturer specifications, independent reviews, retailer data, user reported scale weights, and verified enthusiast sources. Official weights are cross referenced against real world anchors from sources such as BikeRadar, WeightWeenies, Cycling Weekly, road.cc, Escape Collective, Velo, trusted retailers, and documented scale measurements where available.
When exact weights are not available for every size or variant, VeloWeight may use calculated estimates based on known reference weights. For example, if a verified frame weight exists in one size, nearby sizes may be estimated by applying typical size based weight differences across the model range. The same approach may be used for cockpit lengths, handlebar widths, seatpost offsets, crank lengths, wheel freehub variants, and other component options.
These estimates are intended to make the calculator more useful across real world build configurations, but actual weights can still vary due to size, paint, hardware, production tolerance, included fittings, tubeless setup, and small specification changes between model years. Frameset weights may also include or exclude frame-specific hardware such as derailleur hangers, dropout inserts, small bolts, crown race or compression hardware depending on the source, so small variations should be expected.
You can calculate a complete road bike build weight from frameset, seatpost, wheels, groupset, cockpit, stem, handlebar, crankset, pedals, tyres, tubes or tubeless setup, saddle, bottle cages and custom components.
The frameset field is intended for frame and fork weight together. When a source separates frame and fork weight, VeloWeight combines them so the build total is more useful.
Not every size, width, length or variant has a published measured weight. Where needed, VeloWeight uses known reference weights and calculated size differences to estimate nearby variants.
