I got an excellent opportunity this morning to join my fellow mechanics and gaze at the new 2015 Campagnolo Record group brought by the US rep to explain new features and designs. It really packed a punch aesthetically and is sure to be a powerhouse to compete with the other major drivetrains out there. That being said — onto the good stuff!
The first component we looked at are the new shift/brake levers and how they differ from previous generations. The hoods and body of the brifter are the same shape as the prior edition, but have small improvements. The hood has a different pattern that contours the brifter better and helps to eliminate the ‘crease’ that some worn in hoods experience after heavy use. This is also reflected on the inside of the hood where they created a thicker mesh under pressure points for better vibration dampening and a more secure fit. A small print of “Campagnolo” is displayed in white at the outer front side of the hood. Here are a couple photos:
The internals look basically the same with the exception of a different ratcheting shift mechanism that corresponds to the way the rear derailleur will travel up and down the cogs (actuation ratio). This does mean that it is incompatible with the prior generation.
The crank was totally redesigned with the newer four arm spider made of carbon fiber and the chainrings each using 4 chainring bolts to attach to the arms. This, along with the profiling of the top of each arm over the outer chainring is expected to confidently support the near 45Nm torque of the front derailleur shifting from the inner to the outer ring. Also, I should note that the downshift is slightly different and acts much more like its electronic cousin, EPS. When dropping from the outer ring the inner ring, the derailleur will drop to a low trim position — one slight click up from its innermost position. This should help greatly in eliminating a chain dropping. Here is a photo:
Next was the front derailleur which ties into the prior paragraph about the 45Nm torque of the shift. This is an improvement of about 10Nm more than the last generation and only 7Nm less than its EPS counterpart. A 3D molded carbon cage exists on the Record and Super Record mechs and is an alloy cage on the Chorus level. The improvement of the shifting power is mainly due to the added length of the arm used to anchor the cable. Here’s a couple views:
The rear derailleur was definitely the best part about the entire presentation. It boasts an incredibly light weight and features carbon fiber all over in both the Record and Super record levels. The Chorus level will have an alloy outer parallelogram plate. The reintroduction of a B-tension screw will help to eliminate differences in frame manufacturing specifications and allow the derailleur to be dialed in the exact same way on any number of bikes. It’s best feature is a spline drive inside the anchor pivot that winds the spring tighter as the derailleur moves up and down the cogs. Its benefit is to keep the upper pulley moving with the same curved slope of the cogs to prevent missed shifts and smoother transition. Check it out:
Lastly, here are a few photos of the EPS bike with current generation Super Record 11 EPS:
