Wheels are one of the most – if not THE most – critical component on your bike. It is therefore important to think hard before purchasing a set.
Wheels can now be made to optimise cycling performance in almost any discipline, from downhill mountain biking to velodrome riding. They are ultimately a balance of weight, rolling and aerodynamic resistance, strength and comfort.
Of all the components on Rebecca’s bike, this was the one I spent the most time researching.
My criteria was:
1. Weight:
I wanted a compromise between strength and weight; Rebecca is not heavy on her wheels, but I did need a pair of wheels which would be robust enough to ride on roads which aren’t the smoothest. Going too light on a pair of wheel can result in rim damage if you hit a big pothole – though wheel technology is improving reliability of light wheels year on year.
2. Strength:
Sportive wheels need to withstand the rigours of prolonged riding, over hills and poor road surfaces; there is no recovery van or spare wheels like there is in proper racing, so the wheels you start with are the ones you need to finish with.
3. Efficiency:
A good set of bearings and an aerodynamic profile reduce the amount of rolling and aerodynamic resistance; the effects of which build up over time, and since sportives are long events, this is important.
4. Compatibility:
Not one many people think of, but its important all the same – will these wheels work alongside existing wheels? i.e. can I swap from training wheels to these wheels and back again, easily? I don’t want to ride on these wheels all the time. Can I continue to use the same brake shoes (Carbon rimmed wheels need special compound brake blocks)? Can I use my existing gears without adjustment? Will these wheels fit in my frame?
5. Cost:
Obviously, it’s a recession, and I’m not a millionaire – I need wheels which are good value for money.
6. Looks:
And as I’ve mentioned before…good looking equipment is always faster!
So in the end I specified a set of KOOKA KARBA’s from Ebay. These are a “deep rim” set of semi-high performance wheels bought through Ebay via Grahamweighdeeside Cycles on Ebay.

Why?
1. They use Carbon Fibre deep rims; this is important for sportive riding because these provide good aerodynamics, without much weight penalty or wayward behaviour in crosswinds, which affect very deep-rimmed wheels. There is also some evidence to suggest that in combination with a conventional set of laced spokes it improves comfort by absorbing road vibration.
2. They use alloy for the braking surfaces. This is important because alloy tends to provide a more consistent and predictable braking action, and equally importantly, I don’t need to buy any fit any special pads to the brakes.
3. They use conventional metals spokes. In this case, the spokes are “bladed” to provide even better aerodynamic efficiency, but the important reason is – metal spokes can be replaced if they break. A solid carbon wheel on the other hand, cannot be repaired as easily.
4. They use “clinchers”. Clinchers are the normal tyre and inner tube combination most people are familiar with. However, on some high-end wheels, it is common to fit tubular tyres – these are all-in-one tyres which are optimised for racing, and are reported to have the best rolling resistance properties. This is fine if you have a recovery car with pre-prepared spare wheels, but in a sportive you don’t. It’s far more practical to repair a puncture with an inner tube than it is to completely replace a tubular tyre! Not to mention the inconvenience involved of having to lug such a spare tubular around with you.
5. They support “Shimano” 10 speed cassette gears. This is important, because all Rebecca’s wheels and bikes all use Shimano 10 speed gears.
6. Cost: At £300 a pair these represent excellent value for money, and I get full dealer support through our local bike shop in the event of a manufacturing defect or more serious repair.
FITMENT:
Fitting wheels is easy; simply open or close the quick release lever to release or secure the wheel. Adjust the grip it makes on the frame by turning the non-release end of the release, until the lever is able to grip the frame/forks when closing. It should be tightest just as the lever is fully closed. If you cannot close the lever it is too tight!
It’s important to remember a few small things though:
- When closing the quick release, ensure it won’t close against any part of the frame; it will damage the painwork, it won’t actually be properly closed and you may not be able to open it again!
- Always ensure the quick release works against some resistance when closing it; this is how adhesion is maintained. Never ride a bike with a loose (but closed) quick release – it means the wheel is also loose!
Here they are, fitted to the bike
ALTERNATIVES – IN THE SAME STYLE:
- Shimano Dura Ace 7850: Awesome wheels, but sell the kids into slavery first.
- HED Jet 4/Jet 6 Carbon/Alloy Clincher Wheelset: As per above, but you have both shimano and campag options.
- Mavic Cosmic Carbone SL Clincher Wheelset 2010: As per above, but you have both shimano and campag options; Mavic have been building wheels longer than most.
ALTERNATIVES – CONVENTIONAL (non-deep, alloy rim) STYLE:
ALTERNATIVES – “BUDGET”:
ALTERNATIVE – MONEY NO OBJECT:
TYRES
Obviously, no wheel is enough on it’s own – you need tyres, and these are ultimately the most important component on the bike; without them you’re going nowhere, and with poor ones, you might even crash!
Tyres for Sportives need to be lightweight, but durable. They also need to be replaceable or repairable at the side of the road. They must also be comfortable, and last but not least – they must inspire confidence through good feedback and grip in the corners.
For Sportive riding, I recommend the Continental Grand Prix Attack/Force Road Tyre Twin Pack. I firmly believe that because each tyre has a different job to do on the bike, they should be optimised for that task. It’s not essential to have identical tyres front and back!
Rebecca has tested this on her training bike, and they do perform brilliantly – comfortable and easy rolling at the rear, while grippy with good feedback at the front.
ALTERNATIVE TYRES:
- Michelin Pro3 Race Folding Road Tyre: (These are listed as racing tyres, but perform extremely reliably in sportives)
- Schwalbe Ultremo DD Evolution Black Folding Road Tyre (Definitely a racing tyre, but again, better puncture resistance than most)

oooooooooh ! sweeeet ! wish I could help building the bike ! it already looks so wonderful !!!
As you get this new super duper bike you could gimme your old one ! 
can’t wait to see it complete.
Hia Tanja – yes I am very VERY fortunate to have a wonderful husband who does all this for me,… – but it looks like my husband’s job is going to be gone in May – so very hard times coming up for us…we might not see the bike getting finished this year.
If I could give you a new bike I WOULD – I so want to see you on a good bike and getting the most out of your biking…!
Rebecca, I couldn’t agree more on your thoughts on wheel choices. I ride sportives myself and here is the wheel I ended up with. http://www.williamscycling.com/38cc/38cc.html
I ride an aluminum frame and these carbon wheels make the bike feel like a carbon bike with alloy wheels.
Just thought I would share as Williams Wheels makes a great set of wheels with great pricing to comparable wheels on the market.
Cheers,

Hi Rebecca,
Currently I am riding an entry level road bike with Shimano Sora groupset and low end wheels. Which part should I upgrade first – Shimano 105 groupset or new wheelset?
Regards
Mustafa
Hi Mustafa,
This will be quite tricky, because Sora is 8 or 9 speed and 105 is 10 speed. This means that you can’t mix wheels between these two groupsets without changing the sprockets at the same time – you will need to check if your wheels supports both 9 speed and 10 speed shimano cassettes.
However, you might be able to upgrade your wheels first, if your local bike shop can setup the new wheels with some special spacers, so that you can fit your old 9 speed sora cassette to them. Then, when you’re ready, you can upgrade to 105 10 speed and replace the cassette with a 10 speed version.
This entirely depends on the wheels you choose though, so probably best to involve your bike shop about how this can be achieved.
Regards,
Euan

Hi Euan,
Appreciate your response very much. Yeah you’re right – my Sora is 9 speed and I need to check with the bike shop on the wheels’ specifications.
Maybe I should rephrase my questions – given all components are matched, which upgrading will enhance bike’s performance more ? Upgrade the groupset or change the wheels?
Regards
Mustafa
It’s a close call – a new groupset will be lighter, and the new chainset hopefully stiffer and thus more efficient. However that only really comes into play on hills – where weight counts – and/or power moments (eg accelerating away from lights) – where mechanical efficiency counts.
A good set of wheels (and tyres!) on the other hand, will benefit your entire ride – up hills, on flats, down descents. Personally, I’d start with the wheels, but that’s just me. Others here may offer alternative reasons?
Hi Euan
Loved the article – bought the wheels !!!
No instructions, sadly – could you assist with recommended rimtape width and spoke key size, please?
regards
Andy
Interesting article.
The wheels look great with the ribble frameset
Carbon clincher ‘semi deep’ aero rims seem to be a bit of a fashion statement at present. Especially for sportive type rides as their increased rotating weight will always put the rider at a disadvantage. For the kind of price range you paid you will always be compromising on the hub, bearing quality and weight when buying a carbon fibre set of wheels. Even a set a Mavic Cosmic Carbone’s would be looking at a weight of around 1750-1800 g for a set which is pretty heavy weight to be lugging up mountains and hills.
I would have thought the general rule for sportives would be lightweight and reliability?
Hi Liam – these are a top quality pair of race wheels. Just because they are ‘not’ marketed as highly as other wheels and priced ridiculously high, does not mean they are not quality wheels and bearings. We did a lot of research (6 months) before investing in these wheels, asking male Cat 2s and 3s how they found reliability and the answer was they were a ‘fast’ all-round pair of wheels for road racing which even had them on the podium a number of times!
From experience and I AM splitting hairs here: a ‘slightly heavier’ set of wheels (we are talking minimal weight comparisons remember – all these wheels are ‘light’ nowadays) in the mountains is actually ‘advantageous’, BECAUSE of the inertia in the rims you ‘hold’ better for longer per pedal push – ‘the lightest’ wheels are not necessarily the ‘fastest’ uphill! and for all those extra ££££s you pay, most everyday sportive riders won’t even notice the difference in performance or know what the heck I’m talking about. You are right though about too deep a rim – but these are just right – not too deep or yes, they become ‘too’ rigid and more for time trailing not uphill cycling, as you lose that ‘flex feel’…yes, it’s all down to how wheels ride for you and your technique..and for me (female and lightweight, well used to be!), these are perfect.
If you’re a seasoned cyclist or experienced sportive rider and want a good quality, lightweight set of reliable performance wheels, then these more than suffice for the job at hand to get you pbs all season long! Why pay more unnecessarily?
Cheers for commenting Liam,
Rebecca
