Freestyle scooter info for parents and kids
The Raven comes with an IHC fork and standard diameter bars, so you'd need to replace the fork with a standard fork and use either HIC or full-size SCS compression to use oversized bars.
The Fasen Raven uses an IHC fork and IHC compression with a standard diameter clamp and standard diameter bars. You wouldn't be able to use any oversized bars without changing out your fork, clamp, and compression system.
They are both great scooters. The Raven is lighter and stronger, but it's also $60 more. If you are a beginner, go with the Prodigy. If you're an intermediate, go for the Raven.
The Fasen Raven does indeed have IHC compression which is compatible with standard diameter bars. You want the Apex Bol standard bars with a slit cut in them.
The Raven comes with standard diameter bars that fit IHC and Envy Soul bars are standard diameter, so they should work.
Take a look at the new 2015 Envy Prodigy and the 2015 Fasen Raven completes. Lucky has some good ones as well.
