MODEL AND SIZING GUIDE
Felt IA: where to start with sizing
Identify the exact IA variant before comparing its published sizing information.
Everyday Bike Fit catalogue guide · prepared 2026-09-21 · Source dates shown per entry. Independent editorial review pending.
Identify the bike first
Keep IA, IA 2.0 and any FRD designation distinct. A September 2026 source snapshot is not automatically a 2026 model-year claim.
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
1 entries: 1 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.

Uses the centimetre values printed in the product’s size guide. Some feet/inches labels differ from those centimetre values; confirm the limits with Felt before buying. Size 47 appears in the guide but is not offered for this model, so it is excluded. A TT fitter must also check the forearm-pad adjustment range.
| Size | Rider height | Inside leg |
|---|---|---|
| 48 | 152.4–167.6 | 70.8–74.4 |
| 51 | 167.6–172.7 | 74.4–77.9 |
| 54 | 172.7–180.3 | 77.9–83.0 |
| 56 | 180.3–187.9 | 83.0–85.8 |
| 58 | 187.9–195.5 | 85.8–88.9 |
Before choosing a size
Check the supplied front-end adjustment range, seat-height range and brakes. Ask which hardware is included with a used frame.
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.
