Hi All,

I’ve just got a new set of campagnolo bora wto 45 disc brake. 

1) Should I go with tubeless or clincher? I have in mind the continental gp 5000 or vittoria corsa control.

2) which tire size, considering that the rim width is 19mm (internal) and 26.5mm (external). I’d like to go with 28mm but have heard that this could counter the aero benefits of the profile depth of 45mm, because the tire width would end up being larger than the external rim width. 
 

3) if I went with tubeless, which sealant brand to use, and how much to pour into each other? I’ve heard of stans notubes and orange seal, at about 45-50ml per tyre..

 

Any thoughts / experiences? 

Thanks all!

Yeah, I haven’t tried the Corsa so can’t compare them. I’ve ridden on the Contis through the winter and they’ve been faultless for grip (though I don’t like pushing tyres to the edge of grip anyway) and no punctures that haven’t sealed. They do seem to wear out quite fast though but when you’ve got the pressure right (60psi-ish) they feel like you’re floating over the road.

Absolutely, I think playing

Absolutely, I think playing with the pressures until you get the right balance of comfort/speed is going to serve you better. The Corsa are meant to be more fragile, but that’s not really a concern on a fast Sunday best bike I reckon.

1) Assuming the wheels are

1) Assuming the wheels are tubeless ready, go tubeless and make up your own mind. Opinions are divided on this one – I’m tubeless and love it. Haven’t tried latex tubes though and tbh rarely had a punture with tubes….

2) 28mm if they fit your frame – science suggests rolling resistance is actually lower, plus imo comfort > aero for the gains your looking at (unless racing)

3) Muc-off works for me, qty is stated on the bottle but I think it’s about 50ml per tyre for road. I use a small tube to fill through the valve (with the core removed), much less messy! 

FWIW, I’ve setup GP5000TL’s on my Triban RC520 which is notorious for having slightly larger than normal wheels. Setting them up tubed with the factory rim strips was a no go. However binning the factory strip and fitting tubless tape (just 1 layer for now) and the tyres went on with a bit of a fight – just make sure the bead is sat right down in the well whilst fitting. Once over the rim they sealed first time with just a track pump and some soapy water. I haven’t taken them off since but suspect they will have stretched just enough to make the job easier if I need to do it by the roadside. Tyre levers are now in the saddlebag!

Reports are saying the 5000s have very good vibration damping built into the tyre material. This could be marketing bs, but I’d take it over the extra watt saving of the Corsas.

I’m doubtful of that claim too – the tyre material might well affect rolling resistance, grip and durability, but vibration dampening? The big air pocket inside tyres surely has much more effect which is why your tyre pressure can influence the ride quality so much.

I think you are overplaying
I think you are overplaying any aero dividend. The differences will matter for the pros but not for us lot and indiscernable on any ride. One factor you haven’t mentioned though is clearance on the frame, etc., particularly around the back of the downtube and/or any clip on guards. Personally though, I would go 25f and 28b, and get the best bang for the buck all round.
TL is down to personal preference, no point me voicing an opinion there since you already have the wrong brakes ?

Yes, I’ve been running Corsa

Yes, I’ve been running Corsa Control (30mm) since late August; the reviews said they’re a pain to set up Tubeless – I just used more sealant than normal; and they’ve been fabulous, no issues at all.

Another month, and they’ll come off, repalced by the normal Corsa tyres.

OP is referring to the Corsa

OP is referring to the Corsa Control tyres. I’ve been running these (28mm, tubeless) and they’ve been bulllet proof. Not the fastest – you want the regular Corsa tyres for that, or the 5000s, which are only marginally slower than the Corsa tyres, according to bicyclerolllingresistance.com.

Cant comment on the aero side of things. Maybe choose your tyre and contact the manufacturer for its take on which tyre is more aero?

Oh, and tubeless any day of the week. I’ve been running it on all my bikes now and wouldn’t go back. Just top up regularly and carry a tubeless repair kit with you. It’s a no brainer.

5000 none tubeless (go latex

5000 none tubeless (go latex inner tubes if you like to reduce rolling resistance further) 23mm on the front and 25mm on the back, will give you the best combination of aero and comfort.

I’ll second the 28s Conti

I’ll second the 28s Conti 5000TLs. I use Muc-Off sealant, which seems to have a reasonable level of viscosity (if it’s too runny I don’t trust it).  My experience of Vittoria tyres is that they are excellent: fast, supple, grippy, but tend to cut up on UK chipped-surface roads.  So if you’re UK based I’d avoid them, regrettably.

Tubeless – Conti GP5000TLs

1. Tubeless – Conti GP5000TLs are my current tyre of choice though they have a reputation for being tricky to fit (not in my experience and I don’t consider myself particularly skilled with fitting tyres)
2. I like 28mm for the comfort, though having read about the 105% width/tyre ratio, maybe I should be going for 25mm instead. I might experiment with the front tyre to see how I get on with it.
3. Caffelatex works well and I put about 40ml per tyre and top up when I remember (which is nice and easy with MilkIt Valves though they’re expensive for what they are).
