MODEL AND SIZING GUIDE

Marin DSX: where to start with sizing

Start with the exact flat-bar model for commuting and mixed-surface riding.

Everyday Bike Fit catalogue guide · prepared 2026-09-21 · Source dates shown per entry. Independent editorial review pending.

Identify the bike first

Keep DSX, its model number and FS designation distinct. Match the fork and frame variant against the linked specification.

If the year is unknown, look for the model name, size sticker, wheel label and distinctive frame or brake details. Compare them to the source listing. Photographs can narrow a search; they cannot prove identity on their own. Leave the chart unconfirmed until its generation and wheel option match.

What our catalogue holds

4 entries: 4 with published body ranges and 0 with size labels only. No model year is stated in these entries. This is catalogue coverage, not a list of bikes currently in stock or every generation ever made.

Below are up to three entries with their own source information. Search the full catalogue for other variants and years. A source-check date is not a manufacture date, and the current source may have changed since that check.

Before choosing a size

Check your usual hand position and brake access. A flat-bar reach measurement is not interchangeable with a curved-bar bike’s hand position.

Measure height and inside leg twice, barefoot. Where both are published, keep each height and inside-leg pair together. Keep all overlapping sizes for comparison. If the measurements conflict, sit outside the chart or depend on an open-ended band, seek individual advice rather than extrapolating.

Frame stack and reach, when available, describe the frame and not the final hand position. A chart cannot account for every body proportion, component change or riding goal. Check the actual bike’s adjustment limits and arrange a try-out where possible.
