I think the 2009 v-10 has a 1.5'' head tube.there wont be a "09" v10, they only bring out new models when they have something to improve upon the older ones. They dont bring out new models every year like other companies.
yep 09 V10 has 1.5 inch headtube. that's pretty much all they have changed though.I think the 2009 v-10 has a 1.5'' head tube.
I saw a photo about 3 months ago of a v-10 with the 35mm stanchioned boxxer prototypes on it.
And it had 1.5'' - 1 1/8'' reducer cups in it.
