Testo: <blockquote data-quote="Nessunego" data-source="post: 7635026" data-attributes="member: 170970">[URL unfurl="true"]https://beginnertriathlete.com/mobile/ForumThread.html?forumId=1&forumPage=1&threadId=236891[/URL]The seat tube angle is also steeper on a tri bike than a road bike. What this means is unlike a road bike where the seat angle points towards the rear of the bike, the tri bike’s seat in more vertical. This positions the rider closer to the front of the bike and allows the rider to maintain a larger hip angle while in the aero position. This benefits the athlete by allowing them to utilize hamstring and glute muscles more effectively without relying too much on the quad muscles. You need as much energy in your quads that you can manage when it comes time to run off the bike, so minimizing quad strain on the bike portion of the race is crucial to fast triathlon run and overall times. In terms of pure speed and saving energy, a triathlon bike is king."</blockquote>
