Fitting Campagnolo Ergo levers can be tricky but this guide should go some way towards demystifying the process. We covered indexing derailleur adjustments earlier this year, so. Combined, these two guides should keep you out of trouble when tackling this project.

The new Ergo levers present a few challenges that didn’t crop up on last year’s models, so we’ll focus primarily on the small details and idiosyncrasies. In addition, it’s useful to know that Campag levers are now in their third incarnation, so we’ll refer to the new ones as mark IIIs, last year’s models as mark IIs and the originals as mark Is. Remember to hand over the reins to a professional mechanic if you’re in any doubt about the end result, especially for the brakes or when joining the chain. Tools required • Sharp cutters and needle nose pliers • Flat and Phillips screwdrivers • 5mm Allen and T25 Torx keys • A sharp poking device • Oil and grease • Electrical tape or stout duct tape • Sharp medium file • Torque wrench with T25 Torx socket (optional). 1: 1 Peel back the hoods We’ll assume that your derailleur and chain are correctly installed already. Before sliding the levers onto the bars, you’ll need to peel back the rubber hoods to gain access to the T25 Torx nut that tightens the clamp. Be careful – they’re easy to rip and expensive to replace.
