Thank you for the fantastic reply to my dilemma about receiving extra gear ability! Can you explain to me how to verify the yr of manufacture on my Super Report rear derailleur?
Any plan where by to come across a 32t 11-velocity Super File/Record or Refrain cassette?
That is a excellent concern. Here’s the solution from Campagnolo’s Buddy Spafford:
“Aside from possessing a photographic memory for all the moment operating improvements for model years that we have, you can identify several of our elements from some decals and markings on the parts.
All of our factors must have a tiny white QR code decal on them with products codes and serial quantities. These decals incorporate our industrial code which references the design yr of a component. This is an alphanumeric code that has a element category letter adopted by model-12 months variety. For instance FC9-XXXX would be a crankset from 2009. EP15-XXXX would be Ergopower levers from 2015, WH19-XXX for a 2019 design calendar year wheelset, and so on. Listed here is an instance of a single of the decals discovered on a shifter:

In 2015 we started marking factors with model 12 months compatibility engravings in addition to the QR code decals. For example, the 2015 and later elements for Chorus, Report, and Super Report are marked with an [A]. This suggests any factors with this marking will be suitable with every other. For 12-speed the markings are [F], [G], and [FG]. Elements that share either F, G, or each are suitable.

Beginning in 2015, Campagnolo set [A] labels on parts for Chorus, Report, and Tremendous History to show cross-compatibility. Picture: Buddy Spafford of Campagnolo NA
If no decals or markings are present, then people can speak to our business to get support in determining the product yr or answering compatibility concerns. Hopefully, this will help!

And as for obtaining an 11-pace cassette in Tremendous File, Report, or Refrain: I never feel individuals exist. You can get an 11-speed Centaur 11-32 cassette, however it will be appropriate with your drivetrain.
I was asking yourself whether or not you know of any producers that have considering that appear out with chainrings that mesh nicely with SRAM’s flattop chains. I’m not ashamed to confess that aesthetics play extra than a little component in my option of factors, and I’m seriously hoping to uncover a crankset in polished silver. Know of any that may well function?
Wolf Tooth will make a selection of distinct chainrings that are appropriate with the Flattop chain. As for polished silver types: I really do not know of any.
I just lately procured a manufacturer new TRP 2-piece disc brake rotor, 140mm middle lock.
When I put in it employing advisable torque (and also working with a larger sized-sized threaded mounting bolt) I discovered it was fairly warped correct out of the box new. No make any difference how much I altered my caliper and even split the pads apart within my Dura-Ace caliper the disc was rubbing poor on both of those sides. It was even worse than the rotor currently being changed.
I contacted TRP and proper absent they mentioned they would warranty it no inquiries requested. Then, sometime afterwards a U.S.-based rep emailed me inquiring for a video clip of the rotor rub and I despatched it. TRP’s reaction was shocking to me: This is correctly regular and appropriate new out of the box and that all brake rotors have this difficulty when new. It was inside limits.
The response offered was:
“Unfortunately I simply cannot warranty this rotor for you as the movie demonstrates it is inside tolerance. All rotors, regardless of manufacture, will have some sort of run out and will not be flawlessly real.”
I get that rotors will rub primarily after currently being knocked or from heat and have to have to be adjusted with the tuning fork from time to time and I am beautifully able to do this. I’m just truly stunned this is acceptable new out of the box.
In this article is the video clip I despatched to TRP:
I would be intrigued to hear your just take on this.
I have hardly ever read or observed the amount of allowable rotor runout quantified from a disc-brake maker. What I can say is that we see this all of the time. We construct up in between five and 15 brand name new Clydesdale and Zinn bikes just about every 7 days. To do away with brake rub, we routinely do a good deal of truing of brand-new rotors.
Whilst I would agree with you that one particular should to be capable to assume a beautifully genuine rotor out of the box, I have never ever taken this up with any maker of bicycle disc brakes, mainly because it is a lot easier for us to just true the rotor than to consider to get a guarantee alternative. And currently, with the pandemic bringing massive supply-chain troubles to the bike field, basically having plenty of rotors to place on our bikes is about all we can question for — also demanding that they be perfect out of the box — is a bridge too considerably, correct now.
