From choosing a bike to dialing it in.

Choose the job in front of you: find a bike, compare real candidates, understand geometry, record a riding position, or solve a workshop calculation.

Find, compare, evaluate or set up

What do you want to do?

Start with Bike Finder when you are choosing broadly. Compare Bicycles puts two or three exact Archive records side by side. Geometry Analyzer and Bike Fit & Setup handle deeper frame and position questions.

Bike Finder

Help me choose a bike

Answer a few plain-English questions to find Archive bikes in specific published sizes.

  • Simple rider inputs
  • Exact published sizes
  • Archive-backed bicycles
Find bikes for me
EvaluateStart from a real bike or chart

Geometry Analyzer

See what a bike’s geometry means

Search the Archive to load a real bike, or enter a geometry chart yourself. Then explore its frame shape, plain-language analysis and similar bicycles.

  • Bike-first guided start
  • Interactive measurement map
  • Similar-bike finder

Bike Fit & Setup

Record a setup that works

Record rider, saddle and cockpit measurements, then compare the position or reproduce it on another bike.

  • Guided essentials
  • Position worksheet
  • Optional frame measurements

Workshop Tools

Useful calculators for setup and service.

Get clear starting points for wheel building, tire pressure, gearing, suspension and chain length—with the inputs and assumptions visible.

01Wheel Building

SpokeMaster

Calculate independent left and right spoke lengths from ERD, hub flange geometry, rim offset, spoke count and lacing pattern.

Open SpokeMaster
02Bike Setup

Tire Pressure

Estimate independent front and rear starting pressures from system load, mounted tire width, wheel size, terrain, casing and air system.

Calculate Tire Pressure
03Drivetrain

Gear Ratio

Analyze chainring and cassette combinations using ratio, gear inches, development, speed at cadence, overall range and cassette jumps.

Calculate Gearing
04Suspension

Suspension Setup

Calculate fork and rear-shock sag targets, compare measured sag, evaluate balance and work through common ride-feel symptoms.

Set Up Suspension
05Drivetrain Service

Chain Length

Estimate the chain path from drivetrain geometry, account for maximum suspension chain growth and turn manufacturer add-link instructions into a cut-ready worksheet.

Plan Chain Length

Transparent by design. Results show their inputs and assumptions. Manufacturer limits and component-specific instructions always take priority.
