Not sure about the gel seat but their Air seats are awesome, road down to the island 2yrs ago and didn't have it on the way down. Brought one while i was there and then rode home with it. Made a massive difference, for the better. Only 2 catches with them 1) as above they do not require alot of air, almost the less the better 2) If you're hitting up the twistys they move all over seat and after about 10-15mins they will almost fall off, havn't lost it yet though
