I have a 1995 Trek 2300 road bike, the older 3-main tube carbon version, that has a polished aluminum fork and polished stays. Looks very nice. The bike rides rather stiff.
I have a snap story. I was riding the Trek on ragbrai one day with a speedy couple on a 'bent tandem. They would bomb down the hills, it was all I could do to hang in their draft in my biggest gear. Like most tandems and all recumbents, they would slow way down on the up hills. It was like doing interval training at high speed. 50mph, 10 mph, 50, 10 ,etc. Anyhow at the bottom of one hill we crossed a bridge with a raised joint. SNAP! We were going so fast everyone looked at my bike for the source of the noise. Yeah, I was quite nervous about it being on a carbon frame with an aluminum fork. I slowly coasted to a stop, inspected the bike. Rode slow to the next town where I could borrow some tools to pull the fork to check the steerer tube. Nothing. I rode slow the rest of the day. When I got in that night the tandem riders were telling me it was their bike. Snaped an aluminum seat support bracket. They thought it was my bike until they spoted the break later that day. Whew.
