So, looking at the specs on my bike and i'm trying to ascertain the headset size/sizes.

To my knowledge the standard headset is a 1 1/8 straight steerer. Is it possible to fit a tapered headset so I can fit a 1 1/2 - 1 1/8 fork instead of the straight steerer ?

I love the bike, but I want a new fork and its really hard to find a 1 1/8 straight steerer on a fork these days.

Thanks in advance for the help.
