Bottom bracket drop is the vertical distance the BB sits below the wheel-axle line. It controls how low the rider's centre of mass is relative to the contact patches.

Across 56 audited models the Bottom Bracket Drop ranges from 62 mm to 85 mm, with a mean of 74 mm and a median of 75 mm. The mean and median agree closely, which tells you the catalog is not skewed toward an extreme of the distribution — most modern bikes target the middle, and the leaderboard above lets you see who deliberately steps outside it.
The current high-watermark is the Specialized Diverge 2025; the current floor is the Scott Scale Gravel RC 2026. More BB drop lowers the rider, increases cornering confidence, and stabilises the bike at speed. Less BB drop raises the BB, improving pedal clearance for technical terrain and jumps.
| Type | n | Min | Mean | Max |
|---|---|---|---|---|
| Gravel | 37 | 62 mm | 74 mm | 85 mm |
| Road | 19 | 69 mm | 74 mm | 80 mm |
This per-discipline breakdown is the more honest comparison: comparing an XC hardtail's Bottom Bracket Drop to a road frame's is a category error. Use the type rows to find the right peer group, then drill into individual bikes from the leaderboards above. Each bike row links straight to its full geometry page on RideDNA, where you can run a side-by-side against any other audited frame.
If you want to filter on multiple metrics at once, the filter tool lets you set ranges on stack, reach, HTA, trail, wheelbase and chainstay simultaneously and returns every bike that satisfies all the constraints. The discipline pages apply pre-baked filters by riding style, which is the fastest way in if you already know what you ride.
Caveat. Published geometry charts are not all drawn the same way. Some manufacturers publish stack at the top of the head tube exclusive of any integrated headset cap; others publish it at the top of the cap. RideDNA reconciles these to a common reference where possible (see the methodology page for the corrections we apply), but for any single bike you should still treat the chart as ±2 mm uncertainty before you stack-spacer-shop. The relative ordering on this page is more reliable than the absolute values.
