MODEL AND SIZING GUIDE
Giant Contend: where to start with sizing
A road-bike family with archive entries useful for riders shopping second hand.
Everyday Bike Fit catalogue guide · prepared 2026-09-21 · Source dates shown per entry. Independent editorial review pending.
Identify the bike first
Keep Contend, Contend AR and other suffixes distinct. Match the year where known and compare the wheel and brake configuration to the source.
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
33 entries: 33 with published body ranges and 0 with size labels only. Documented model or catalogue years represented: 2026, 2025, 2024, 2022, 2021, 2020, 2019, 2018, 2017. 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
When two size bands overlap, retain both candidates. Check the exact frame and component setup instead of carrying your size across from another Giant family.
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.
