The gel seats are great. Here are the down sides. The fabric will hold water. So if it rains while you are grabbing a snack, your but will be wet on the way home. The gel holds heat! If you drop in for a bite, grab a bag of ice for your seat. Otherwise you will have some schwetty balls for the rest of your ride. The gel doesn't cool down very fast. But they are definitely worth it.
