I am going to upgrade my commuter bike. I ride a giant boulder. I have a lot of good components on it. When. I upgrade this bike, the existing parts are going on a 2009 giant se. I love the frames and they are cheaply priced. I have a Surly Instigator fork, and juicy 3 avid 160mm disc brake on the front. I wanted to put a little bling, bling to the bike. I bought white industries hubs for the wheels. Now, I want to replace the fork with a Ritchey Mountain WCS Carbon Rigid Fork, and replace the disc brake with a Avid Elixir CR Disc Brake 203mm. I know you are going to say, I am crazy for wanting these high end parts. But, I love my bike, and have saved all year for these new parts. This is my late Christmas gift to me. I save my money for traveling, and bike touring. I save money for bike parts. Now with this said, can this combo work:Ritchey Mountain WCS Carbon Rigid Fork, and Avid Elixir CR Disc Brake 203mm. Jenson USA has these parts on sale. I would welcome other suggestions. I don't want to buy a high end bike, I just want to buy the components to replace the old ones. This frame has 7374 miles on it. Most of those miles are touring. So the frame is very comfortable for me.
