I have finally finished upgrading my Trek 7.5FX. It is truly awesome to ride, but the project was somewhat absurd given the amount of investment that is now in the bike.
But I love it.
- 2009 Trek 7.5FX, satin nickel color, 17.5" frame
- Full Ultegra SL 10-speed drivetrain, including crank (triple 50/39/30), BB (Hollowtech II), FD, RD, chain and 12-23 cassette. Actually the FD is a Shimano FD773.
- Shimano R770 flat bar shifters (same as those that are stock on the 7.7/7.9)
- Avid SD SL brakes with Shimano XTR levers
- Mavic Ksyrium Elite wheels with Bontrager Race Lite Hardcase 700cx23 tires
- Easton EC90 carbon flat bar
- Richey WCS carbon seatpost
- Shimano A530 pedals
Overall this bike is a rocket. The Ksyrium Elite wheels with 23mm tires give it a highly responsive road feel, as does the flat bar.
The bike is also much lighter than stock. The stock bike weighed in at 23lb 6oz. Currently it is 19lb 7oz, excluding the saddle-mounted water bottle cages. At least half of the weight reduction is due to the wheels (although the seatpost and handlebars contribute materially to weight reduction as well).
The shifting is incredible compared with the Deore/LX stock setup.
Strangely, the Avid brakes also make a huge difference. Much more so than I expected. The stock SD3 brakes on the Bontrager SSR rims were just terrible.
I realize the pedals are a bit out of character with the rest of the upgrades. I was going to put some Time RXS pedals on to make it compatible with my road bike shoes, but (a) I wanted to be able to use mountain shoes and (b) I wanted a dual pedal with a platform on one side. These are the only features that make the bike a hybrid, IMO, since it implies you can ride it to the store or somewhere where you might want to get off the bike and walk around and thus have walkable shoes. But as far as going on trails, etc, the wheels and tires pretty much take that off the agenda for this bike.
Most people will disagree, but I found the stock saddle perfectly comfortable. So I kept it. I've taken rides as long at 75 miles on this bike and never had a problem with staying comfortable in the saddle.
I won't get into how much I spent on all of this, other than to say that I got the wheels used from Craigslist but most of the other parts new from various internet sources.
Now the problem is when to use this bike. I rode it a bunch last summer but this summer my goal is to do a triathlon so I am training exclusively on my Felt S22 and I haven't ridden the modified 7.5FX hybrid even once. I also just got a CAAD9 road bike, so I fear this flat-bar beauty will languish in my basement. Ironically, my problem is now that I no longer have a "hybrid" to use on trails!! Of course I could put on some other wheels with wider tires.
I should probably put it up for sale on Craigslist, but of course that would just quantify the absurd over-investment I made. I'll probably just use the bike around the city (Chicago) this summer.
And I need to give a shout out to Panthers for giving me the idea to go down the path with these mods.
