Has anyone tried friction shifters on a 10 speed Campag drivetrain? I want to set up a TT bike and would like to have friction shift levers mounted on the bar extension,

re:Updating a fossil
In category Tech issues
Written by SideShowBob36

Well, the urge to update the old road bike to get it into the 20th century has struck. It has a Shimano Tourney rear der with a stem-mounted friction shifter, and I'd like to replace the shifter with an indexed version. My question is, what's likely to work with that old 5-speed rear, from among the stuff that I'm likely to be able to find available either new or used?

freehub and downtube shifters
In category Tech issues
Written by Andy Cowell

I have a rear wheel that has a Campag screw on hub. The BB on the frame is
Shimano.

I would like to utilise it as a commute/trainer bike and so would like to just have a single 42T chainring and use a wide range of sprockets at the back.

Could I use a downtube friction shifter so that there would be no indexing problems with the Campag/Shimano setup?

Given this, what rear mech would you recomme

So I 've gotten the bright idea into my head to try and do the Mt.
Washington hillclimb this summer. my current setup is a double chainring and I'd like to convert to a tripple. what is the bare minimun I need to change out? my assumption is:
-Left Ultegra STI lever -> STI tripple (or add a downtube friction shifter cause I've got one on hand, whoo hoo)
-Bottom Bracket (I assume an ultegra d

re:Dura Ace versus Ultegra triple

Written by DavT

Okay, here I go again with my vague understanding or Shimano triple setups.
I read at the Shimano site (details on Dura Ace triple front derailleur) that the MINIMUM drop from the large ring to the middle is 14 teeth.
MINIMUM it said. That would seem to indicate I can't use the Ultegra crankset I have with it. My question now is can I simply put a 39 ring in the middle of my ultegra triple crank

From triple to double on a Trek 5200 with Ultegra 9 speed
In category Tech issues
Written by jellyphisher

Considering that I'll probably go ahead and get a dedicated commuter bike, I won't need a triple chainring on my Trek 5200 anymore (not here in Maryland anyway

The things I'm looking to for going to a double are:
- Improved chainline. Right now the chainline is pretty poor. If I pedal backwards while on the largest cog, middle chainring, the chain often moves to a smaller cog because of the a

Will Chorus and Record Ergos shift Double & Triple?

Will 10 spd camp ergo shifters work with both double and triple cranks if the proper deraillers are used or do I need to buy a special Triple STI unit like I do with Dura Ace?

re:Parking Break - What are your thoughts on this?
In category Tech issues
Written by thor0298

I took the kickstand off of my bike. I found that I never used it because I always lock my bike to a post or bike-rack anyway. And if I did use it, I was always at some risk that my bike would get knocked over. I always think a bike looks better without a kickstand anyway. But, when parking, it is often times a hassle getting a bike situated so it won't flop to one side or the other. Think about i

I experienced the dreaded speed wobble tonite on a 38 MPH descent.
So, I've since read many of the posts on this topic, including those by Jobst Brandt.

My case. I have a 1984 Centurion Comp T/A that has about 25,000 miles on it, the first 23,000 with the original Shimano 600EX components, and SR Laprade seatpost, stem, and handlebars. This was a decent downtube, friction shifter setup. Never e

Will a 20 year old Huret front der work with an STI left shifter (triple) and narrow chain?

If yes, how much better will a modern front der work? It will be used with a Stronglight 99 crankset (47-36-28)

Can any of you direct me to a derailer that will shift 24 / 35 / 51?

I've got this super gear pattern worked out that requires these even front steps.

MTB rapidfire shifter on Shimano 600
In category Tech issues
Written by Croaker

I'm considering buying an old road bike with a complete Shimano 600 series drivetrain and would like to make it into a city cruiser with a MTB style handlebar. I would therefore like to put a MTB rapidfire shifter on the bike instead of the old non-indexed frame located shifter. I don't plan on using the front derailleur at all.

How much do I have to change in order to achive this: both the cogs
