MODEL AND SIZING GUIDE
Giant Trinity: where to start with sizing
Begin with the exact TT frame, then move to the forearm-pad position it can achieve.

Identify the bike first
Distinguish Advanced and Advanced SL, the documented model year and the installed front-end parts.
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
35 entries: 28 with published body ranges and 7 with size labels only. Documented model or catalogue years represented: 2027, 2025, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015. 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
Frame height bands are preliminary. Compare a sustainable pad stack and reach to the exact front-end adjustment chart, including required hardware.
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.
