Straight Bars/Drop Bars

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Straight Bars/Drop Bars

Hi,

I have a GT ZR 4.0 road bike but prefer straight bars. I've spoken to a couple of shops, one said that it'd be fine to change them over, but one shop said it would cause a problem with the geometry/weight balance.

Could anyone advise please?

I wouldn't worry excessively about a "geometry/weight balance" problem. Besides, you can always change it back.

This is the kind of project that tends to "grow" as you go along. You'll probably need new shifters and brake levers that match the components on the rest of the bike. You'll probably want a little shorter stem but that's OK because the clamp size is probably wrong anyway. With a more vertical seating position, a slightly wider saddle may be more comfortable.

Once you start messing with your bike this way it tends to become addictive and you may never be able to stop.

I built my and my wife's latest road bikes flat-bar style and we love them (well, she loves hers; I obsess over mine...).

The Grouch pretty much covered what you'll need but be aware that Shimano MTB shifters will work w/ road rear derailleurs but not fronts; different length control arms.

Also, don't get hung up on claims of incompatiblity of flat-bar brake levers w/ road calipers; I do these conversions all the time and have yet to find a real issue.

I recently put on a trekking handlebar (see Nashbar.com) to give me more hand positions. I love it! I put it on my Marin hybrid and have taken it on a 35 &45 mile ride, no hand numbness now with the various positions. It was an easy conversion as the bike came with the flatbar. Good luck, that GT you ride has a nice frame.

How much money does this conversion cost? You're talking about a lot of parts.

Bikes designed for flat bars (e.g. Fuji Absolute) typically have longer top tubes. Others that just retrofit a road frame have a really upright riding position. I converted my rain bike to flat bars and found that even with a longer stem, it was too upright a position for my liking and converted back. I just sold the whole bar, 8spd rapid fire shifters, levers, stem, bar ends, cables and bar tape for $40.

I know that's what Shimano says, but I don't think so. I've worked on lots of tandems and some "fast hybreds" that predated the new flat bar road shifters. They shift just fine.

I need to see those on a bike, just for ****s and giggles. I can't imagine riding on the lower horizontal drop things (I don't even know what to call them)

The truth is that it can be any amount. I know because I've done stuff like this both ways.

If you want your bike to look "factory" when it's done, then you'll want to get the "right" matching parts. They are going to be harder to find via cheap sources and are likely to cost more. If you buythe good stuff at regular retail prices you could be talking $300.00 easy.

If you're not so into esthetics, you can use a soda can shim with your current road bike stem or even get everything except maybe cables and housings off of a police auction donor bike. Out-of-pocket cost this way might be under $25.00.
