I had my hi fi for a month, I absolutly loved it for the first couple of weeks, but after that I began to have my doubts.
When I first got it I was blown away with how easy it was on the back wheel. It also made sidehops easier, however my other things were worse off, gaps, taps and so on where just crap. I thought it was because it was a new bike so it didnt bother me, but when after a month I was still shit I decided to sack it off.
People also say high bbs are great for natural, I found it the complete opposite, I couldnt ride it to save my life! I would just fall off for the most stupid things. My balence isnt great, but with the extra unstability of the hi bb, I just couldnt keep the bike under control.
I also got super harsh on drops because I couldnt get my weight far back enough over the bike to make them smooth.
