How the maker describes it

endurance-oriented geometry

Maker explicitly identifies endurance geometry. Stated 36 mm clearance meets the GnR >=35 mm Endurance All-road house rule; this is not a fit or terrain guarantee.

Verified tire clearance

36 mm. Exact page states 36 mm maximum. Actual tire width, rims and fender setup need separate review. All-road is GnR’s ≥35 mm Road Endurance house rule, not an industry standard.

Mounts and carrying

Manufacturer states fender mounts; verify tire clearance with installed fenders.

Exact Caledonia T47a chart, not Caledonia-5. Stack and reach match the stored Caledonia-5, but wheelbase and several standover values differ; separate chart retained. No older Caledonia year equivalence or stock claim. Frame measurements exclude cockpit and spacers.

Published frame dimensions

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

Aggressive longer reach than the fixed benchmark at this stack · Balanced within the benchmark band · Relaxed shorter reach than the benchmark at this stack

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 555 mm, reach 378 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.
