Converted from flat to drop bars on trek 7.5

I've seen a lot of discussion on converting from flat to drop bars for "Hybrid" or "Fitness" bicycles. I'd though I would share my experience. I have ridden my Trek 7.5 FX for about 5 years. I've put a few thousand miles on it including some fairly long (600 mile) loaded touring. I was mostly very happy and comfortable but I wanted more hand positions - including a more aerodynamic one. I researched a few options and decided to convert to drop bars.

I considered buying a second bike (cyclocross or road), but the ones I looked at (mostly Cyclocross bikes) had pretty much the same geometry as my Trek. I also figured I could go back to flat bars if it was really not working out - and not spend $1200+ on a bike.

My research turned up one big issue. Although I have Tiagra 9 Spd derailleurs, I couldn't use the Tiagra STI levers since they are not compatible with the V-Brake found on my bike (and many other hybrids). I looked around and found a few options, including the "Travel Agent" to increase the cable travel and still use the STI's with the V-Brake. That seemed kind of kludgy to me. I found some drop levers that would work with my V-Brake, then I needed some 9 spd SIS shifters.

Here's what I did:

I bought Nitto Randonneur (45 cm) bars for $50. I liked the upward slope and the wider drops.
I bought Cane Creek V Drop Levers for $50.
I bought Shimano Dura-Ace 9 spd Double/Triple Bar End shifter for $90.
I bought new brake cables and 8 feet of cable housing from my LBS for $20.
I bought some new bar tape for $20.

Total cost was $240. It took only a few hours and I was out riding. I needed only two hex wrenches, diagonal cutters, a flat screwdriver, pliers, white grease, and some tape (I used clear hockey tape rather than electric - it was handy).

The brake levers were easy to install on the bars and cabling was easy. I re-used the V-Brake "noodle" on my brakes, but replaced all other housing. The shifters were also pretty straightforward. I was surprised how easy it was to run the cable and housing from shifters to derailleurs. The Dura-Ace works great with the Tiagra rear and delivers a nice "chunk" feel as it shifts. Very different than my flat bar thumb shifters. The front shifter is a friction setup and works on my triple crank very well. I had to decide how to run the shifter cable housing up the bars and exit the bar tape. I decided to exit the cable and housing about half-way up between bar end and brake hood. This was just a matter of trying a few taping options.

Overall I am very happy. I am quite comfortable on the bike in several positions; in the drops, on the hoods, on the flats. I left my current stem for now, but might swap it out as I ride more and need to make some adjustments based on new riding position. I also swapped my 700X32 tires for some 700X28 and now I can keep up with some of my road bike friends

Cross/commuter/Touring bikes are essentially the same thing.. drop bar hybrids, you just took the long way there.

Good report! I have a 7.5 FX myself, and I have a feeling that I will want to do something like the OP did down the road.

Nice job on the conversion. I was contemplating the same thing but I don't have your technical acumen. Perhaps I'll take your instructions to my local mechanic.

Right. I did take a few photos, although not very good ones I see now. One of the flat bars before and one of the bike with the new setup.





I realize this is not for everyone. I like fiddling around with the mechanical aspects of the bike.

I've been looking at this idea with my bad boy, but today decided that it's going to be too expensive for me.
I was wanting / looking at:
105 Sti levers $180.00
Swap my MTB disc calipers to Road disc calipers $80.00
New Rear deraileur (Deore long cage) $48.00
Drop Bar (used) $10.00
10 speed cassette $33.00
Chain $23.00
$374 !!!!
Came to my senses (for the time being) & asked the question, why would I do this when I have a road bike?
I had no answer.
