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 561 mm, reach 396 mm) among current gravel 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.
