The Invert Supreme 2.5 Pro Scooter comes with IHC compression, which will hold your scooter together much better than the threaded compression system on most non-pro scooters. The integrated headset sets the 2.5 apart from the 2.0 and is a huge upgrade despite being the only difference. An integrated headset will spin much smoother than a non-integrated one and is easier to change out if necessary. The 2.5's wider deck will provide a little more grind room and foot space. The steel bars are very strong and will hold through rigorous riding. The 110mm wheels on the scooter are the industry standard and will spin faster than smaller 100mm wheels.
