How the maker describes it

BMC Endurance Formula

BMC calls the Roadmachine its endurance bike and publishes the geometry under the "Endurance Formula". Verified 40 mm clearance meets the Ryan/William 35 mm All-road house rule.

Price scope and source

Roadmachine complete bikes, 27a listings, from Roadmachine THREE Vibrant Red (low) to Roadmachine 01 ONE Chameleon Petrol (high). Model year: Not stated on pages; image file names indicate 2027 (BMC code 27a).

Low end checked on the Roadmachine THREE product page, high end on the Roadmachine 01 ONE product page. No Roadmachine X build was priced. Displayed USD prices on 2026-10-17 for 27a listings only; 26a prior-year builds shown on sale and framesets are excluded. Low-stock and out-of-size wording is not an availability claim. The collection pages rendered only part of the listing, so an unseen build could price outside this range.

Verified tire clearance

40 mm. Manual: max 700x40c, up to 40 mm measured, 4 mm clearance around the tire. Manufacturer limit for the named frame; actual tire width, rims, fenders and setup require a separate check. All-road is GnR’s ≥35 mm Road Endurance house rule, not an industry standard.

Mounts and carrying

Maker lists fork and frame fender mounts on base models, top tube mounts, D-Fender compatibility and downtube storage. No rack or load limit is implied.

One chart is published for the Roadmachine Gen 3 series. Manual and series sheet agree on every loaded value. The sheet does not say whether Roadmachine X models share the chart.

Published frame dimensions

Lengths are in millimeters. Head angles are in degrees. Frame stack and reach do not include the stem, spacers or handlebars.

Where this frame sits

Each dot is one published frame size. The green band is GnR’s fixed geometry benchmark. Frames to its right have longer reach at the same stack (Aggressive); frames to its left have shorter reach (Relaxed). The benchmark does not change with bike type or catalog additions.

Comparable frames from other brands

Each is the closest match to this frame’s size 54 (stack 570 mm, reach 383 mm) among current road frames from other brands.

Prices are the maker’s US list prices for complete bikes on the date shown, and include sale prices on that date. Ranges cover only the named builds, not every bike in a family. Framesets, tax and shipping are excluded. A displayed price, including an archived sale price, does not establish stock or a purchasable offer. Retailer prices and later changes are not tracked.

Find alternatives to this frame

Use this exact chart as your reference, select your size, then explore similar dimensions or a deliberate position change. Confirm the frame generation matches your bike before using it.

Does similar geometry mean the same fit?

Similar frame dimensions are a starting point. Saddle height and setback, seat-tube geometry, stem length and angle, headset spacers, handlebars and control position affect the completed bike. Review those details before buying.
