So I did get the Fisher Hoo Koo E Koo mountain bike and oh man is it nice.
I did ride the Tassajara but only got a block before I turned around (I had already ridden the Hoo Koo E Koo). There was no comparison: the handling, the shifting, the braking. The Tassajara was ok, the Hoo Koo E Koo was awesome. It's more than I wanted to spend ($1050 to start) but given that I keep bikes for 20 years and I already have the money especially when I sell the Trek, it should be fine.
I did also buy bar ends and a new seat. Ian who was helping me pointed out that I need a new helmet since mine is a 2001 and they only last about 5 years. I decided that I'd get one from REI when I returned the WRB seat that I got from REI. Ian picked out the seat (a Specialized Women's one) and it's so nice.
This is also ironic as I can't ride much right now since my foot is unhappy, but I'm glad that I did it. It's also a 2008 model Hoo Koo E Koo, so it's not like it's going out of date anytime soon.
I listed the Trek on Craigslist and within 1 1/2 hours heard from 3 people. I don't think any of those inquiries are going to pan out but I can tell that I will sell it this week. I do need to locate some flat pedals for it as the only pedals I have for it are the clipless SPD one's that came on the Fisher (I'm keeping the ones that were on the Trek - well they were on the BikeE).
I so looking forward to riding it (probably at Redwood Regional Park to start with) once my foot has healed. During the test ride, I did ride it up the hill on UCB campus and it was so nice.
