Does tri bike geometry change saddle choice?
 

Obviously there is a big difference between a comfort saddle and a road saddle. Is there any different needs for saddles when riding tri geometry bikes versus other bikes? I never seen this issue discussed but just wondering if the aero position works best with a different saddle type.

yes. there are saddles made specifically for triathlon. They have more padding in the nose. To get a good aero position, you rotate your pelvis, putting pressure on different parts of the anatomy. (and if you don't get a good pelvic tilt, you're even more crammed up, with more pressure on sensitive parts of the anatomy.) I have a quinta roo saddle specifically for tri bikes on my tt bike and it makes a big difference

I agree with the previous post, but the width of the nose is more important than thick padding. Profile has a new saddle that many people find comfortable when sitting out on the nose when in the aero position.

I presume you are talking about something like this:

Thanks for the hints. I almost goofed.

What dictates a saddle FIRST is your fit on that particular bike. Some saddles will not have the rail length or may place you off of the saddles sweet spot. So Bike Fit first, then understand "of the available saddles that would work" which you would like to use based on your drivers of either weight or comfort or a compromise of both and then for some "cost" plays into the decision as well. After that your choices are among the select few that work to with your given criteria.

Yes, the saddle is indeed very different, for all the reasons described above.

Here's my favorite saddle:

Super comfortable when tucked in and not bad at all when upright climbing. Can't say that for that many saddles...

Agree with all the answers before me, but wanted to add one more point. Many tri saddles (I ride the Aspide Tri) also are more flexible in the nose and are overall longer. This is important as it can allow more comfortable positions on the bike while still staying aero.
