|do handlebars have the shifter locations marked?||Fez|

|I am getting new handlebars and plan to do the swap.
Are the shifter locations marked with some sort of lines or do you have to eyeball it?
Markings would also help make the left and right shifter mounts symmetrical.

|Did a search and didn't find much, except for one post that thought Shimano hoods were "flatter" than Campy hoods.
So what is the rule of thumb for installing Shimano shifters on the bars? Should the lowest part of the drops be parallel to the ground, and then the Shimano brake hood be installed so that it is nearly flat, with the levers turned very slightly inward for crash/scuff protection?
Thanks in advance.

|.....the bars are installed so the drops are parallel with the ground, then the shifters are installed so a straight edge (ruler) run along the bottom of the drops would meet the tip of the shift lever. However that doesn't take into account personal preferences of positioning your hands while riding. Also different bars have different bends and curves further clouding the positioning issue.
What I do is mount the bars and shifters like I said, then either go for a ride on put the bike on the trainer, with the bars untaped. I re-position the bars and shifters until I find something that is comfortable, then tape the bars.
Also don't tighten the shifters on the bars so tightly that they won't move in a fall. I snug my down just until a good smack with my open palm will cause them to pivot on the bar.
That way the levers don't get too munged up or break.

|I just went through this with the position of my Deda Magic handlebars. The old school rule-of-thumb, bars parallel to the ground and using a straight edge to the tips of the brake levers, won't work with most of the new era stuff, especially the anatomic bars.
The suggestion about finding a comfortable angle for the bars, using the bars untaped, is a good way to go. As once you get the cables cuts and the bars taped it's a bit of a chore to dial everything in.
My Deda bars are angle way too far up for my preference, but I'm going to wait until spring when I install new bar tape and re-adjust the angle and move my Ergo shifters up the bar.
Also if you are using Campy Ergo levers they require a lot of messing around with to find the angle you feel comfortable in. I like mine so they are level with the tops of my bars, the Shimano on my other bike are tilted up a tad.
I was getting a bunch of mixed opinions on bar tilt so I emailed Deda directly and they told me that bar tilt was a matter of rider preference. And if you look at videos or photos of the pro peloton there are a lot of varied angles out there..

|I think most people recommend that you hold something like a ruler tightly against the bottom of the drop bar section of the handlebar and position the shifters so that the bottom point of the shift lever just touches the ruler. Then make minor adjustments to this position based on you personal preference. I don't think the shifters should be angled away from 90 degrees perpendicular to the flats on the handlebar.|

|Getting them symmetrical can be tricky, but as for the positions, there's some leeway. The Rivendell website used to have (might still, but I haven't checked) several examples of ways to position the levers. One accepted way is to point the ends of the handlebars at the rear brake, then hold a straightedge along the bottom of the drops and place the levers so they touch the straightedge. If you're more comfortable with them somewhere else, though, there's no reason not to do it.|

|...is not that tricky anymore. Take your bars off the stem and lay them on a flat piece of the workbench. Install the levers roughly where you want them, tightening only one. If they are not symmetrical (usually they won't be), you will feel a 'jiggle', like a table on uneven ground. Now move one of the levers until the movement is gone and tighten. Voila!!
Also, if you need to make adjustments to the levers with the bar on the bike, bring the dog to the bone, i.e. take a flat piece of board to the bottom of your bar and repeat the process.
