105 Disc or Ultegra with calipers?

I live in Norway guys, no riding outside for the next 4-5 months for me anyways. Been on Trainerroad/KICKR Core the last seasons. 
 

I think I could go with 105 and calipers, as the performance is almost identical. My old 6800 groupset is probably less of a performer than the R7000 maybe anyway. But still; non-carbon shifters? Naa.. it must be Ultegra. I cant cheap out on 105. I think Ive decided for the CF SL 8.0 Ultegra with rim brakes. I got a couple of wheelsets to use in the wets anyway. 
 

My current bikes are 53 and 52cm. Canyon says I should go for a XS frame since Im about 172cm. My girlfriends brand new Endurance CF 7.0 with 105 disc is a XS and it feels ok. Even tho Canyon says its no difference between mens and womens bike sizes. 
Also, the Aeroad CF SL 8.0 is not avsilable in silver in S, only XS. 
I could wait for the new model, but how much better could it be? And do I need it? Definetly no. So a 2019 bike is good enough for me. Question is if the will have a sale and The bike is still in stock at that point. 

I’m 175cm, and my orthers bikes are 54cm, I have Aeroad in S, it is more cramped, but as it’s supposed to be an aggresive position thats to be expected. If you don’t want an agressive dropped riding position, then might as well go for an ultimate instead.

deffo  go no disc, there’s absolutely zero need to go disc in any weather conditions and calipers are ridiculously easy to maintain and replace pads. If you’re one to ride in constant wet/mud for 10,000+ miles a year, live in a hilly area and use carbon rims then discs might be a consideration based on cost of wearing themout, otherwise you absolutely don’t need them.

Aethetically it’s a no brainer to go caliper brake.

I have a canyon aeroad, and this is not true, braking in the dry is fantastic, braking in the wet is minimal, to the point where it’s hard to lose any speed going down anything over 10%. Ignore all these traditionalists telling you disc brakes are not better than rim brakes. 

However, unless the aeroad is going to be your only bike, there is no need to take it out in the wet, keep it for best and enjoy it in the sunshine, keep it clean, and rim brakes are fine.

Also aeroad comes with very nice expensive wheels, riding in the wet is a sure way to need to replace these sooner than neccesary as the brake blockes collect grit.

Aesthetically, functionally, extra tyre clearance and for the sake of those lovely carbon wheels. No brainer has to be disc. Maintenance also very simple.

How much tyre clearance do you need, a short drop 49mm caliper accepts a 28mm tyre on a race frame (that’s not the newer Shimano 8000/9100 that are 51mm), with better design that could be increased. We know for a fact that calipers such as the 57mm TRP957s are as good as Campagnolo Skeleton brakes, well according to Stu Kearton on this site in his review of such so increasing the tyre clearance on a racing frame designed for caliper brakes is in fact easy to do, 31mm with a mudguard I’ve done and without 35mm.

That’s before you even get to Vs/Mini-Vs, are there any road based disc framesets that can take 700C 42mm tyres with a mudguard or 50-55mm without, there have been in the not so distant past road based framesets including full carbon that have been able to accept very wide tyres with rim brakes, I know because I have a selection, off the peg from one of the big manufacturers so it has been entirely possible.

Aethetically and functionally a no brainer, explain? The former I understand is subjective, cleaner lines of a caliper braked bike to me look far better, functional, in terms of more weight and less aero for discs as well as being more expensive compared to similar spec bike how is a disc braked bike better functional/wear wise on carbon rims except for the very extreme scenario I gave above?

Are you going to argue that outright braking power is functionally better – ignoring the risk compensation aspect of that, also ignore that braking power is totally irrelevant to stopping ability when the limiting factor is tyre grip?

I’m not going to argue with you at all. It’s a completely pointless exercise in futility. Your mind is made up. In your previous incarnations I cannot recall you ever having made any claim of actually trying disc brakes but nevertheless your mind is closed.

Personally I currently have bicycles with both types and the one with rim brakes is a Dura Ace setup. My actual, real experience over many years and thousands of miles is that disc brakes are functionally superior. Aesthetically I think they look modern and suit the more organic lines of carbon frame bikes. For skinny steel classic rim brakes look better. My opinion.

Rim brakes are perfectly adequate, but I’ll be enjoying the descents with one finger braking and the superior control of disc brakes thankyou very much.

Make sure you’re signed up for their newsletter to get info about any sales that happen…and pull the trigger if they have the bike you want.

Else I think you’re crazy paying full price for a bike that was designed over 5 years ago and is about to be potentially replaced…when you cant ride it for another 5 months anyway!

Your choice anyway. A few of my friends have them and love them, you wont be disappointed

Learn to read the road

Exactly, reading the road, riding to conditions, if it’s wet it takes all of a few seconds to dry your rims, and frankly, if I’m riding in wet conditions, I have no interest in setting PBs on descents anyway!

A few pieces of rubber grinding away at a wet aluminium rim is no way to stop in an emergency

And a few pieces of hardened metal and fibre grinding away at hard steel are? I’m being flippant of course but rim brakes are far better designed than people give them credit for, soft rubber pads are far less prone to the sort of squeeling in wet conditions which puts me off discs altogether, wet winter riding is unpleasant enough without adding humiliating, deafening screeching into the mix. As it happens I ride through some long wet grass on one of my CX training loops and my discs are useless afterwards, they don’t work as well in the wet as everyone claims they do, still need to dry off!

Good Swisstop pads on aluminium rims have seen me through some atrocious weather conditions, riding down a rivulet of melt water on an unploughed road covered in compacted snow springs to mind, and I’m on the same rims as I was two years ago (although sharing winter duties over two bikes helps that).

Anyway, as someone above posted, this argument will never die, it’s down to personal choice, I just find the ‘no brainer’ attitude a bit hard to swallow.

I suppose the other point is that 105 vs Ultegra is a head vs heart debate. This is a specal bike, so will 105 move you in the same way as Ultegra?

If we’re talking about being moved, the debate really needs to be Chorus vs Super Record 🙂

H11 shifters & chainset + SR mechs + Chorus chain & cassette currently comes in at £850 on bike24.com, if you fancy a DIY build. That is a ludicrous bargain.

But that wasn’t the question!  You have to wonder why Campag stuff is being sold off so cheaply though don’t you.

In answer to the original question, discs every time.  A few pieces of rubber grinding away at a wet aluminium rim is no way to stop in an emergency.  Learn to read the road; disc brakes are fine; don’t need discs and all the usual arguments dont account for the need to carry out an emergency stop in the wet or the fact that a pair of brake blocks can wear out in 3 or 4 wet winter rides and a pair of aluminium rims can be trashed in 2 winters.  A no brainer, disc every time.
