Across the 8 closest matches in the catalog the Ridley ASTR RS 2026 fits a recognisable cluster of Gravel bikes. The neighbour set was selected only from the same bike-type bucket and only from models for which we have a full stack/reach/HTA/trail/chainstay/wheelbase/BB-drop record — so the distance numbers above are like-for-like, not apples-to-oranges.
The single closest geometric match is the Litespeed ULTIMATE G2 2026, with a normalised distance of 0.1 mm of stack and 13.9 mm of reach separating the two. Riders who liked the position of one will almost always feel at home on the other.
Ridley ASTR RS 2026 runs about 5.2 mm less stack than the median of its closest neighbours, so this is the more aggressive pick of the cluster — better for race fits, lower bar drops, and riders who want their stem closer to the steerer-tube cap.
Ridley ASTR RS 2026 runs about 9.4 mm more reach than the median of its closest neighbours, so the cockpit is longer than its peers, which usually pairs well with a shorter stem and suits taller torsos.
The Ridley ASTR RS 2026 sits almost exactly on the trail mean for this peer set, which is a strong signal that the brand built it to a familiar template rather than chasing a niche fit.
Use the side-by-side comparison links below to drill in on any specific pairing. Every comparison page on RideDNA is computed from the same audited geometry tables that power this list, so the numbers will be internally consistent. If you'd rather start from your existing fit, the Fit Wizard takes a few of your current bike's measurements and re-runs this same nearest-neighbour search from your seat, not from a brand the manufacturer chose to compete with.
Method. Each of the seven metrics is z-scaled by its standard deviation across the candidate pool before being summed in the Euclidean norm. This avoids wheelbase (typically ±50 mm of variation) drowning out HTA (±2° of variation). We deliberately do not include subjective scores in this similarity calculation — the goal is geometric kinship, not handling kinship. Two bikes that share geometry but pair it with very different fork offsets or tyre clearances can still feel different on the trail; the Handling Index page is the better tool for that question.
