Well i never really tried hard actually,i would try maybe once every couple days while i was riding but eh,then finally today i just went to a parking lot in philly and learned it in about 30-45 mins of trying and getting over the fear of leaning too forward...

my ratio is... 46(Dawes sst stock? im pretty sure thats what the website says) and the back is a 15 i think? so 46/15? haha i might be wrong
