The 'Un-Official' Campagnolo Ekar thread

[cribbit]

Everyone's talking about how well priced this is and I still can't believe a mid range group is $2k.

Carbon fiber, machined 1-piece steel cassettes and technology/design costs money. If you think about the $2k price, hell, it's barely mid-range. It's almost on the bottom of the mid-range. With SR12/EPS, DA Di2 and SRAM Red AXS, that really pushes the range limits down.

It's 'get real' pricing in the epoch of Covid.

Looks pretty awesome, well make not that logo on the cranks.. Can this work with rim brakes? I'd put this on my Zank cx frame if so.

No. It won't work with rim brakes. Disc only kit.

Boooo... So why make this group 13 but the road groups 12? why not make them all 13?

3t is offering ekar on their road bike.

I suspect the cassette/freehub design limits how small they can go with the largest cog making most of the cassette options larger than what many would want on a true road bike. I see people wanting 25 and 27t large cogs on 12 and with 13, you may not be able to go below 34t or so like shimano 11spd mtb. Above that and you are likely looking at a perfect application for ekar. Below that, do you need 13 cogs?

Any idea of whether the RD will shift an 11 speed cassette properly? I really would just like the clutch

No idea about the RD, but it would be interesting if it did work with other generations.

As far as ISO frames go, there are a couple options. Magura MT8 (maybe others) calipers, Hope "Shimano" version, and as such could probably use Shimano or TRP calipers if you came across a good set. Basically you need to have a Mineral Oil caliper, that requires a similar amount of fluid displacement on pull of the lever. (Joosttx just updated his MTB from Magura MT calipers to XTR calipers)...

I am nearing completing of my Magura MT8/Potenza build, and am looking forward to getting some time on the levers, just need to get a replacement hydraulic line because the used group I bought doesn't have enough length.

I know they're pretty rare and old, but so too are the bikes (and riders) that seem to frequent these halls.....

So, I've wanted to go down this path for a while, as I have a set of eTap HRD levers plumbed to Red22 Hydro Rim brakes on my Holland.

The biggest problem you'll see with the Magura version (and the Campy levers) is that they don't have a brake release built into the caliper like most mechanical brakes do (the Campy levers don't have the release button we love either), requiring the user to deflate the tires to install or remove them. I had stumbled across a Di2 hydro bike using the above Magura Calipers. User

I think I have a solution, but its a bit convoluted and isn't an inexpensive route.

If you (or anyone) really are interested in what I'm thinking about, send me a PM. I'd be happy to walk through my idea and how I think it will work.....

I’m sure that’s coming.

I just bought GRX di2 with Easton 46/30 adventure rings and an 11-40 cassette, so I’m good, but this group set looks dope. Definitely makes sense if you are considering mechanical/hydro 1x. I hope this ends up being a commercial success for Campy so that they can keep innovating.

The critical components of a bicycle should carry the names of lesser known mountains and hills more often than is currently used by the manufacturers of these parts. I applaud the use of this name.

That's what duct tape and a Sharpie are for.

What's the max gearing range % for Ekar?

Depends on how you define range.

9-46 cassette gives either 466% (42/9) via ratios of largest gear divided by smallest gear, or 366% for total gear ratio span.

Helpful article on the second method:
