ergolever mounting surprise - back to 5mm

[AngryScientist]

as far as i can recall (correct me if i'm wrong...) all of the 11-sp campy levers, including the new 11-sp shaped hood veloce and centaur-10 used a T-25 wrench to install the clamps.

installing a new set of centaur-11 shifters today, fishing around with my T-25 wrench, no go. pull up the hood to look - back to 5mm allen key to mount.

interesting.

additionally, i like the new matte black look of the new centaur kit.

They probably use a steel bolt to save some $ and not as concerned about weight as in the levers using a Al T25 bolt.

Perfect! A hex head style nut in the correct location to use a ball-driver hex wrench!

[Veloo]

I agree with BD. Sounds like a cost-cutting move for that calibre of parts.

+100. I'll sacrifice a few grams for ease of installation... and durability of the nut.

Definitely.

My older SR-11 Gen.1 have the T25...can't stand them. The H5 are so much easier (plus all older levers (10-S) had the H5, correct?).

Have carved out more than a few metal shards with those T25 splippery wrenches. I’ll take a hex when there is an awkward angle any day

The Potenza's use a 5mm also.

The new Centaur kit looks surprisingly nice. It will look awesome on my 1998 Ritchey Road Logic.

I ran over the same situation than the op with potenza... 5mm aswell.

Just curious: does anyone know if you can take the 5 mm hex nut from an older lever (say mid 2000 10 spd.) and replace the aluminum T25 on the newer levers? I have some of the former that could be scavenged.

I haven’t seen it in person, but in pictures, I prefer centaur’s all matte finish to the mixed gloss/matte finish on Potenza. The silver centaur also drops the odd dual finish found on Potenza.

Yes. I've done that and wish I had more.

Didn't realize Centaur was available electric!

edit: can't speak for 12 speed

It’s not. Centaur and Potenza have EPS shaped levers because they can only upshift one cog at a time. This restriction means they only have to pull one cogs worth of cable and that allows them to rotate the lever downward.

Potenza and below use a steel 5mm allen..Centaur and Potenza. All above use a SR part, aluminum and T25..

[ultraman6970]

Yes you can, what you can do also is just use brake caliper nuts aswell, some campagnolo brake calipers come with extra Txx nuts.

No need to pull back the hood. Just insert a long Torx head or allen head driver down side along the lever. Goes straight to the bolt, without peeling hood back.
