Bicycle Mechanics - 27 speed brake levers?
Bikeforums.net is a forum about nothing but bikes.

I recently got a Novara express bicycle and was considering putting drop handlebars on it. In my searches of looking for the right components that would go on this, I could not find levers that would accommodate 27 speeds, or were under $300. Do they exist? Thanks

current sora and tiagra is 9 speed. if you have a mtn type FD the drop bar shifter wont work for the front.

Look for Shimano Tiagra ST-4500 or ST-4503. I believe ST-4501 is double-specific.
Here's a set: http://www.cheapbikeparts360.com/products/shimano-tiagra-4500-9sp-sti-shifters/

Looks like your bike came with a flat-bar road FD, for use with flat-bar shifters and road cranks. You'd be best off also getting a standard 9-speed triple road FD, such as the FD-4503.
Cool. It would have been frustrating finding out this derailleur wouldn't work the hard way, so thanks for the info!

Ryan - I've got a Marin Mill Valley from REI that I'm contemplating doing the same. I was going to copy the setup on the SURLY CROSS CHECK. 27 speed, Shimano Tiagra FD (same as on my bike). The cross check uses Shimano SL-BS77 9-speed Double/Triple Bar End Shift Levers...about $75-$80 on the web (Tree Fort Bikes)
9 speed Tiagra is an easy conversion.
Your Novara has SRAM FD. SRAM currently makes 10 spd bar end shifters $100. I wldnt try Shimano to SRAM unless you can return em if they dont work. I would contact SRAM directly and ask what bar end shifter they make would work with the X7.
And check out: http://www.cyclechat.net/topic/66636-suitable-bar-end-shifter-for-sram-x7/
Here's the site for the CROSS CHECK.

AFAIK, no bar-end shifter will work with a SRAM X7 rear derailleur. Until SRAM's new 10-speed stuff came out, their road and mountain RDs used slightly different amounts of cable pull in different parts of the range of motion. Neither Shimano or SRAM road shifters will work if that is the RD that you have.

There needs to be a FAQ entry or a sticky for hybrid-to-drop-bar conversions. Same questions every day it seems like.

Taken from the GURU Sheldon Brown site.......AND if you search their site they say the Shimano Ultegra 8 Speed unit work with a 7 speed cassette: their quote " The 7-speed units are no longer available, but the 8-speed shifters actually work quite well with 7-speed cassettes, especially with modern rear derailers"
So logic would be the SRAM 10 Speed would work with the SRAM 9 speed cassette. Hence the suggestion to contact SRAM. .......They are the experts.....
Bar-end shifters are the most versatile of handlebar-mounted shift options for use with drop handlebars. (http://www.sheldonbrown.com/gloss_dr-z.html#dropbar) Modern ones are indexed (http://www.sheldonbrown.com/gloss_i-k.html#index) for the rear derailer, but use friction (http://www.sheldonbrown.com/gloss_e-f.html#friction) shifting for the front. As a result, they are compatible with all front derailers and all chainrings.
The Shimano models even offer a selctor on the rear shifter that permits it to be used either as an indexed (http://www.sheldonbrown.com/gloss_i-k.html#index) or friction (http://www.sheldonbrown.com/gloss_e-f.html#friction) system.
Bar-end shifters work particularly nicely when used with a "low-normal (http://www.sheldonbrown.com/gloss_l.html#lownormal) " derailer.
