New Campy SR Wireless
 
In my opinion the new Campy SR Wireless groupset sure looks fugly. The bulbous front and rear derailleurs are awful looking.

It's not pretty but then again there's not any attractive electronic groupsets

Let's be honest, just about every groupset for a while has been fugly. I have noticed a few SS groupsets that don't stick out like a sore thumb. In fact, they look invisible. :roflmao2: If it shifts gears, and is not C & V, it usually is fugly looking.

I'm not so concerned with aesthetics, but I see a lot of missed/botched shifts with those paddles.

Still better than the long throw, crunchy feeling of a Shimano brake lever shift.

That sets the bar pretty low

Broken down tube friction shifters are better than anything Shimano has made in decades

Yes, but look at all the other things on that bike that we use to call ugly and have since gotten use to.

As a Campagnolo fan, I’m stoked on this! I mean, there’s very little chance I’ll throw down $5k for Super Record, but once the tech trickles down to less expensive model ranges, I’ll be happy to have choices other than SRAM.

TiHabanero 05-31-23 04:59 AM
I just don't understand why SR looks so big and bulky in the pictures, but the Sram wireless does not. What did Campagnolo do to create such a massive looking derailleur set?

Wireless disc brakes seem like a recipe for trouble. What happens if your battery dies on a long descent?

Don’t be silly…

It's so far out of my price range that looks are irrelevant.

I think if we ever got there on bikes there would be a fail safe or two or just have a dynamo and run brakes off of that if it was an issue. Cars have been using it and no major problems we have heard of there. Not saying it is impossible but what if a cable snaps or a hose leaks or a pad falls out or your grease gets cooked out or...you can come up with a lot of scenarios on current brakes that are less likely to happen not impossible of course.

I am personally not awaiting wireless braking and probably won't run it for a long time if it ever comes out but I do believe that they would have a fail safe built in and they wouldn't make that unsafe of a product.

TiHabanero 06-01-23 04:09 PM
Got to looking at the Wireless SR components and realized the disc brake calipers have a delta shape to them. Thinking they should be given the name of Delta II. Kinda neat to have that fabled namesake back in the line up!

I'm excited and bummed. So happy Campy has gone wireless because then I could get electronic shifting on my older daily driver, but alas disc brakes put a kibosh on that. I'm really bummed they dumped the thumb shifters.

Apparently, it's here already. According to the article:

Campagnolo Super Record Wireless disc brake calipers

https://images.immediate.co.uk/produ...size=620%2C413 The calipers receive cosmetic updates and new, lighter DB-410 pads. Oscar Huckle / Our MediaThe Super Record Wireless calipers are flat-mount only and share the same internals with its other groupsets.

There are some cosmetic revisions, with Campagnolo’s signature winged wheel logo printed on the inside face of the caliper.

Campagnolo is introducing new DB-410 disc brake pads, though, which are 30 per cent lighter than the current DB-310 model, thanks to a new aluminium backing plate. Bearing in mind the DB-310s weigh a claimed 41g, this saves around 12g.
https://images.immediate.co.uk/produ...size=620%2C413 The lever bleed port location is unchanged. Oscar Huckle / Our MediaLike Ekar, the brakes use Campagnolo’s proprietary red mineral oil brake fluid. The bleeding procedure is unchanged, although the brand no longer recommends the use of Magura’s Royal Blood fluid, which was used previously on its road shifters.

The calipers are designed around the use of 140mm disc brake rotors, with 160mm discs requiring the use of an adaptor.

Campagnolo Super Record Wireless disc brake rotors

https://images.immediate.co.uk/produ...size=620%2C413 The rotors are also a carry-over item. Oscar Huckle / Our MediaThe disc brake rotors are unchanged from previous incarnations. Their patented rounded shape is said to regulate temperature and reduce risk of injury.

Campagnolo says when it was originally developing the rotors it undertook medical laboratory research and experimented with fake skin to find the best shape.

The discs are available in 140mm and 160mm sizes in Center Lock only and continue to be 1.85mm thick – a little wider than Shimano and SRAM.

Campagnolo continues to use a floating design with seven rotor carriers on the 160mm rotor and six on the 140mm.
https://images.immediate.co.uk/produ...size=620%2C413 The rounded profile is claimed to prevent injury. Oscar Huckle / Our MediaThe brand says a small amount of play is built into the rotors. This can be felt when rocking the bike back and forth with the brakes locked. Campagnolo says this enables the brake to better absorb heat when descending.
No mention of fail-safes, but perhaps they are part of the package.

I think you’re confused; the groupset name is Super Record Wireless, and the brakes in the SRW groupset are, as the article you quoted says, run on mineral oil (via hoses connecting lever to caliper). In that regard, they’re like virtually every fully hydraulic bicycle brake system out there…all of which are technically wireless.

You can see the actual hydro hoses the shifting is wireless but the actual braking is standard hydro stuff. That article does make it a little confusing without the pictures.

I wonder if we'll see this grupo on Le Tour 2023 . . .

I of course dunno how much of a factor it is with regards to overall sizing, but I’d suspect that having on-board charging capability accounts for some of it. There’s the port, and I can only guess some associated circuitry, too.

I have no way of knowing— it could be battery capacity, perhaps a bigger, high-torque motor, or just more robust components— so just speculating here.

Atlas Shrugged 06-02-23 12:20 PM
Overall I am indifferent about wireless as managing another set of batteries doesn't seem necessary; the only advantage to wireless is during the bike build stage, which for most is done by the bike manufacturer or in a shop. Once built it may be decades before it all needs to be removed and reinstalled. That said not sure of the logic behind making the batteries specific to each derailleur rather than common like SRAM.

I find it very interesting that with all the hype around Campy Ekar and 13 speeds that the newest and “best” thing Campy is making right now is 12.

Did they finally get to the point of diminishing returns? Is 13 just not worth it?

Ive heard Ekar (mechanical) is awfully finicky. I figured they’d try to smooth it out by using electronic shifting.

I find all this way more enlightening than whatever some anesthesiologist puts on his Calfee.

I have 2 Ekar bikes and I find them about the same level of finicky as the 12 speed SRAM GX I have on my Fat bike.

And I am an engineer, not an M D. My wife and I share one car and I commute by bike, including sometimes the fat bike in the winter.

Interesting to hear that. I have 12 speed GX on my MTB and there is no level of finick. I’ve adjusted the cable tension once.

The Ekar setup seems tricky. Also remarkably affordable for Campy. SR has always been about clout, still is. I was trying to think of a well paid person who would use it on an expensive bike.
