Future of Rim Brakes

I wanted to give you some feedback on the C64 disc versus the C64 rim brake. I built both bikes to almost the same exact spec.

Disc vs. Rim brake
Frames: C64 disc vs. C64 rim
Groupset: Both are using SRAM Red 11sp etap.
Brakes: SRAM flat mount HRD vs. Dura Ace direct mount
Wheelset: Campy Shamal Ultra DB vs. Campy Shamal Mille (ceramic coating)
Post and Seat: same, C64 post and Fizik Arione CX
Bars: FSA Metron Trimax 4D, 44cm
Stem: Colnago integrated cable stem (120mm -8d) vs. Easton EA90 (120mm -10d)
Pedals: same Look Keo HM
Tires: Same, Vittoria Corsa Graphene 700x28
Weight (with cages) 17.5lbs vs 16.6lbs
The DB C64 is about 500g more due to the heavier levers, having rotors, and differences in weight in the braking calipers.

The feel.
The DB C64 feels more solid/heavier in the front end due the lever weight and rotor. It also feels "more solid/heavier" also because the levers are just bigger/chunkier than normal levers.

Braking is better, but, with aluminum rims, I did not have an issue. My rim brake C64 already had the best rim braking possible (direct mount DA calipers, ceramic coated Campy rims, and non-compressible brake housing). I can see if I was comparing it to a rim brake bike with carbon wheels, the disc brakes would be a huge improvement.

Either way, both bikes are great. The frames are identical in feel. 500g difference doesn't really matter to me. What actually matters to me is that the rim brake levers are smaller/thinner and fit my hands better.

Thank you for posting this! This is amazing that you get to try both. As good as apple to apple comparison that people never get to do. I bet the Blue bikes are faster.

It's not quite inspiring enough to deserve as many gasps and ooos and ahhs it receives (by me as well), but I enjoy riding it. I'd happily post a longer review if you're interested and/or unable to test ride one.

Love to hear your impression of the bike. Including your brake experience. Thank you!

I live in San Francisco, it's foggy in the morning and I live on a hill...I'm good with rim brakes when the weather is nice but if there's moisture, I'm on disc. so if this is gonna be a sunny day bike, rim is fine.

Why would anybody want a bike from the Ernesto era? Vanni Brambilla, the son-in-law of Ernesto has been the designer of all new Colnago bikes for well over a decade, so I don't see your logic in specifically wanting a Colnago of the "Ernesto" era.

IMHO, direct mount brakes are an improvement over the traditional center-post mount calipers. I have discs on my gravel/all-road and Campy DM's on a road bike with Bora wheels. Out on the road, the braking is not substantially better wrt modulation. Perhaps the force required is lower for the disc but that benefit alone (for me) doesn't justify the added complexity.

Agree we are not talking about regular rim brakes for the C64, we are talking about DM and the bike is designed to take a 28mm easy.

Yes, plus 'modern' rim brakes(dual pivot) and 'modern' rim brake rims were made for what, 3 decades?..so, 'future proof', IMHO, really isn't an issue.

Unless the OP is looking to solve a problem, I'd say for a COLNAGO, rim brakes all the way. Campagnolo, BTW...

And, just for info

Well, my new rim brake Bora WTOs do their fair share of squealing at times. Toe in did not help much, I'm hoping it will quiet down once the pads wear in a bit.

Colnago is a UAE company now, right?

Regenerative electric braking, built into the hub.

Will provide all the power you need for your Garmin 8830 or iPhone 22...

Rim for road. So simple and elegant. No drawbacks. Less weight, less complexity, more compliant, easy to adjust. What’s not to like?

Coaster brakes.

You ride one up the hill and the other down the hill?

I have both rim and discs. I prefer them for different reasons. For a “road” bike with clearance for a 28 or less, rim brake.

Unless you are buying it knowing you’ll be selling in the future. Then disc for resale. If it’s a long term buy, rim brake.

Perfectly stated. 1000% agree.

Not long ago I added a disc brake road bike to the fleet and am less than enthused with it. I haven't learned to adjust disc brakes and the seem to often go out of adjustment. My rim brake bike is simple, adjustable, brakes nicely, and plain easy. Lighter too. Unless larger tires (>28mm) are required, I think I'm staying with rim brakes.

That's the exact same color as mine. I wasn't sure about the color when I got it (but found a good price while travelling) but now I want all my bikes that color

I like the look of the disc bike slightly more above. Bare frame is so nice.

[old_fat_and_slow]

I thought conventional "rim brake" rims were going the way of the dodo. I thought most of the pre-built fancy pants wheels were all going to disc brake models too. If that is the case ... I would think twice about buying a new bike dependent upon a dying brake system that may have limited choices in the future for wheels.

(No I'm not a disc brake advocate. Don't have any in my stable. Just sayin'.)
