So I have a 06 Iron Horse 7Point5. It's my first DH bike. Ive ridden Walmart bikes forever so I was totally eriksson to get this. I've ridden. Bootleg and Mt Charleston.. I know this bike is heavier than most. And I'm like 5'4 and about 160. Not a big guy. I feel like id be able to better control my bike if.it was a little lighter. Is this an accurate assumption. If so any recommendations on the bike I should save up for.
