That's a very good question to be honest?
The carbon wheels are for my mud guarded Ti bike, which I am being honest with myself is real over indulgence and unnecessary. The bike is currently fitted with Hunt Aero Wide Race wheels, which are more than good enough to be fair
That said they did make the bike superb for climbing and really worked well in terms of looks. I'm currently having discussions with Zed wheels at the moment to see what they can offer.
You will see in the For Sale section that I'm selling my beautiful summer bike, Trek SL8 Domaine Disc, its four years old but Ive never really gelled with it. This was endorsed last Friday when I went out on my old and trusty Scott CR1 Pro for a change, and its everything that the Trek isn't I'm afraid.
So the Trek is up for sale and I'm booked in for a bike fit in two weeks time with a view to getting a new summer bike. The Trek cost me £4.5K four years and despite my best efforts and many bar / stem combinations, I just cannot get it to work for me. Rest assured, I am not making the same mistake again, hence the bike fit!
It will probably be a Ridley frame that I go with, subject to the dimensions working for me and I would really like a Noah Fast. Which means that the money I was going to spend on the carbon wheels for the Ti bike will probably go in the pot towards the new Ridley bike now.
Thank you Alan for the comprehensive answer.
I lusted after bright red Trek Domane in my LBS window in May 2020. I'd just bought a new Cube Axial which I actually rather liked - it was basic, Claris and rim brake, but progress felt quite rapid. I part exchanged the Cube for the Domane - what a mistake to make! Where the Cube fizzed the Domane, despite the looks was a dullard, it felt numb and lifeless. I suspect it was due to the isospeed system.
The next day I went back and bought a NOS 2018 Emonda instead - what a difference despite both bikes being carbon, both being on the same wheels, and much the same finishing kit. My memory of the aluminium Cube though was that it still just had a little more fizz. The Emonda is probably the best compromise for me though, and I'm now at the stage where I'm upgrading the previous upgrades and it just keeps getting better. The Emonda is certainly a climber's bike and a competent descender. A change of wheels improved acceleration.
It's talents are much greater than my own to be honest. I don't race, but I do like to have a go at segment times on ridewithGPS and Strava. That's a little sad I know but I do manage to surprise myself with how I compare with others half my age or less - so I'm hooked.
I've buggered about with set ups too. I've changed bars, stem, settings etc. I watched a clip of Australian bike fitter, Neil Stansbury, recommending a particular saddle. So I bought one after having tried others. It's the SQLabs 612. It's a bit firmer than I was used to, but just as Neil had said, it makes me sit differently, and weirdly I'm suddenly finding more power.
I suspect you are a fast rider and that the Domane was just too tame for you. They are loved though by those who want a comfortable endurance bike.
I'm very interested in those ZED wheels. If you do buy a pair, will you please be kind enough to let me know what you think of them?
