Apart from the maintenance overhead I’ve found disc brakes to be great – especially when it’s raining. However, I’m toying with getting a lighter and sportier bike with rim brakes (aluminium rims… carbon clinchers make little sense to me) and am wondering if I’ll miss that wet weather performance.
What do you think? How close can rim brake performance get to disc brakes?

I’ve found isopropyl alcohol
I’ve found isopropyl alcohol and fire remove contamination of metal pads 100% of the time so far. Bed in and you’re good to go. But yeah, washing is a pain. I generally remove the discs and pads now when I’m doing a serious wash because I don’t want to go through the above rigmarole.

I guess many factors need to
I guess many factors need to be considered in a balanced way….. personally you choose which you prefer and whether you are in need of the “next big thing” in cycling.
From my perspective from the workshop floor….
How about the additional cost replacing freewheel bearings. thru axles reduce the space available for the bearing, hence bearings sometimes only last 1000 miles maximium.
Cost of organic pads that work best in the dry but disintigrate at the first sign of rain.
Extra hassle cleaning the bike…. which is subjective to how OCD you are
If rim brakes get splashed with chain lube their performance will not be affected provided the oil is washed off, do the same with disc brakes and another set of pads is required or they don’t work.
Discs require constant heavy use to remove any contaminant, the amount of pads which will be replaced… kerrrchiing….
Dread to think how dangerous disc brakes would be on a road bike in heavy rain.
And finally…. tyres.. can they take the extra loads on heavy braking…. wide MTB tyres spread the load..a set of 23/25’s I have my doubts over
My perspective from in the saddle…. I’m sticking with rim brakes and decent pads personally…
Whatever, you pays yer money and takes your choice

Most rides are 1-2km in climbs and short gradients of 10-25% are present. There are hedges and there are crazy young drivers in hot hatches. There are also steep drops!
My discs are QR which means maintaining and setting them up is a real chore versus rim brakes as you say. Additionally they will rub when (very!) hot and will also rub when grubby/wet and cornering sharply due to fork/skewer flex. In reality these are very temporary and minor issues but I will admit that’s an influencing factor in moving to the Super Six (albeit a small one since all of these problems are solved by thru axles I gather?)
Are you serious?
I have no problem sitting my disc brake wheels into place with QR. Not sure what your problem is.
With disc I just have to slide back in and never have to worrya bout re adjusting the pads like I did with my dura ace rim brakes.
Come on.

No, they can’t. But why not
No, they can’t. But why not stick to riding your new bike in the dry and use the disc brake bike in the wet?

NO.

Anyone tell you otherwise is just stupid. I wouldn’t bother to read it.

Also to consider……..
Also to consider……..
What sort of terain does your cycling generally take you through? Discs probably hold a bigger advantage over rims if you live in the Lake District than if you live in East Anglia. I live in the latter & spend most of my time trolling along flattish roads, straightish roads with little by the way of hedges and as such (stupid as it may sound) breaking doesnt have a high priority and my rim breaks more than meet my requirements. When I took my self of touring (with a camping load) through bits of the country that had nothing but hills and the roads upon which I traveled where narrow, twisting and bound by high hedges I appreciated the extra ‘modulation’ that my disc breaks provided [That said…… The first time I used disks & encontered that famous ‘modulation’ I was strongly reminded of how a well set up pair of centre pull brakes would feel – one of these days I’ll find a frame on which I can mount my old Mafac’s & test that memory out]
And – your brakes place in your world extends beyond retardation…. Maintainence is much easier with rim brakes & from what I’ve read just swapping wheels can be a bit of a pain with disks due to subtlety different disk alignments. If you only need one wheel set than that’s <obviously!> no problem but as soon as you want to have different sets for different occasions it’ll start to niggle every sodding time you fancy swapping them over.

If you use rim brakes on
If you use rim brakes on aluminium rims U WILL DIE – It must be true becase I read it on the Internet.

I guess these debates have
I guess these debates have been going on in some form or another since the Safety or Rover bicycle first appeared in the 1880s much to the disgust of the pro cyclists, racers and established cycling community of the time who looked down on the “dwarf machines” from atop their “ordinarys”.
I think it would be fair to say that every cyclist currently using disc brakes has experience of rim brakes. Generally they find discs better for any number of reasons.
It would appear that the die hard disc haters have little / no experience of actually using a technology that they are passionate about despising.
In my experience both rim and disc brakes do the job, but personally I definitely prefer the disc.

Yeah, I think we should end
Yeah, I think we should end it here before it becomes a debate about helmets and car doors 😉
So the conclusion is:
1/ Ali with rim brakes can be great
2/ Disc brakes are better in all circumstances
3/ You’ll regret moving back to rim brakes
That’s what I suspected. I’ll just wait until I can afford the new HiMod Evo with discs (or an Izalco Max or whatever it is I end up buying to sate my sporty needs) then.

I sort of get where
I sort of get where SuperPython is coming from, and I have a rim-braked road bike that I am not likely to be getting rid of any time soon. But that said, when you pull the lever in the wet with discs, you’re braking, not setting the scene for some braking a bit later on. That is just better, and TBH I don’t really see why anyone who’s ridden discs would argue that it isn’t. That alone is a big plus to me for urban riding in particular, and that’s before you get into rim wear.

I do get where Superpython is
I do get where Superpython is coming from. Part of his point is you shouldn’t really be needing to be hitting the brakes that much anyway. I could ride my motorbike at silly speeds and instead of braking if I eased off the throttle in the appropriate place before hand there’d be no real need for braking. I could enter a 30 zone at 30 scrubbing off loads of speed from just sitting up into some nice wind resistance. You can ride fast and smooth and it’s even easier on a bicycle given the low speeds. Descents are the only place I ever scrub a load of speed off.
This said I’d still buy discs over calipers at the moment. I don’t have experience of top end calipers but I know that entry-mid level stuff is crap compared to entry level discs, especially in the wet. Probably better to be overbraked rather than under. Then again, if you don’t know the limitations of either then you’re still doing down or into something.
