If I feel like I'm not doing enough work in a group ride, I can take longer pulls, or race up climbs, or whatever. Exertion is much more down to how hard I want to work, than to the bike I'm riding.
If I want an easy day but still want a group ride, I don't hop on a fast bike, I ride with a slower and/or steadier group.
