Cero RC45

The Cero RC45 carbon fiber bike wheels are a result of 18 months of development to improve on our award winning Cero RC50.

These RC45 road bike carbon wheels benefit from a wide 23.5mm outer rim width to improve the stiffness and intergation withe a 25mm or wider tire

The RC45 carbon bicycle wheels weigh in at 1479g (weighed on 12/07/2016) +/- 1% and use a Sapim CX-Ray spoke and nipples and our 298g Cero hub set, the overall result is uncompromising performance with lighting fast speed and stability.

Cero Wheels are striving to offer you the best wheels for your road bike experience and have received a 9/10 from leading U.K magazine Cycling Weekly

*Wheels are provided with QR, valve extenders, Carbon brake pads and rim tape.



We recomend a rider weight Limit of 100kg


Rim: The full carbon Cero RC45 rim features a 23.5mm wide profile which integrates well with a 25mm or wider tire, the U shape also allows for increased stability in crosswinds. The real showstopper is the improved braking performance and heat tolerance capability of the wheel thanks to some innovative technology in the rim track that helps manage and reduce the heat generated from braking.

Hub: Sharing the same superb Cero hub as the AR30 wheel which is designed to offer a superb balance of weight and performance, the 280g set are manufactured from 7075 aluminum and features high quality sealed bearings throughout with a 24 ratchet engagement on the Aluminum hub body combined with a 3 pawl and spring engagement.

Spokes:  Our Cero RC45 wheels use the Sapim CX-Ray spoke. The CX-Ray still receives the best results in fatigue testing of any spoke. Its unique strength and flexibility make the CX-Ray the perfect choice for our wheel. The middle section of the spoke is drawn then pressed in a special mold to form its specific profile.

-Longer lasting than any other spokes on the market. Extremely high fatigue test results.

-The best aerodynamic spoke available.               

-Produced from high-tensile, fatigue-resistant 18/8 stainless steel conforming to the Sapim quality standard specifications.


We are sure you will enjoy the performance and ride quality of our great value carbon wheels

* Required Fields



Cero hubs are a light weight racing hub and some consideration has to be made regarding wet weather riding and deep winter use. The seal is a contact diaphragm and requires little maintenance but if moisture gets in, it won't get out and can therefore wreck bearings quickly. It is up to the user to keep on top of that. Neglect them and they will let you down, just like any other hub or any component on a bike.

Overall the frequency of bearing or mechanism failure is directly related to hours used and the frequency of the maintenance regime.

All the wheels in our range have incredibly light hubs with press in sealed bearings, contact seals on each end of the rear hub and a diaphragm seal between hub shell and freehub body. When it comes to replacing bearings they’re as cheap or expensive as you want - depending on quality. Fitting new bearings effectively gives you a new hub. Freehub bodies are available at £35 each for Shimano. They are all 9/10/11 speed.

 There is no such thing as a maintenance-free component on a bike, sealed bearings etc do require care and attention.


Recommended maintenance before each ride:

1. Check for damage and excessive rim wear

2. Check for loose or under-tensioned spokes. Tighten where necessary or get a bike shop to do it properly

3. Make sure the wheels turn true and freely. Any resistance, check where it’s coming from

4. Change cartridge bearings if any excessive play develops.

5. Make sure all bladed spokes (typically Sapim CX-Ray) are sitting properly

6. Check skewers are clamped properly

7. Make sure tyre pressures are appropriate to the tyre/rim combination

8. Ensure brake pads are positioned and tightened correctly


Recommended maintenance after each ride:

1. If wheels are wet, wash gently with cold water

2. Oil and grime will need a gentle salt-free detergent

3. It is best to degrease a cassette and chain off the bike

4. If heavily contaminated with salty water or mud, remove tyre and rimtape and flush out rim

5. If water or contamination has entered freehub body, remove, clean & regrease

6. Clean brake track and pads or discs with a silicone-free cleaner

7. Make sure your wheels are completely dry! (Leaving bearings damp can lead to corrosion & premature bearing failure)

8. Clean around bearing seals and hub end caps

9. Re-fit wheel to bike, ensure skewers and brake pads are positioned and tightened properly

10. If you don’t feel confident about carrying out the work, speak to someone who is.

Brilliant wheelset Review by ian121
I've been looking to get a set of carbon mid depth wheels for nearly 2 years and read up about many of the wheels in the £800 bracket. Fulcrum, Mavic, Hunt, Shimano etc. I kept coming back to the RC45. In terms of build quality, bling and value for money they are absolutely spot on. My mates are amazed at the transformation to my bike,
(Colnago CX Zero Evo) both aesthetically and to the performance and I really do notice the difference when heading north of 37 kph and on the short sharp climbs around the Midlands. I'm so glad I bought these. Yes the spoke pattern and J bend lacing is a little traditional , but saying as they'll be used on Belgian cobbles next year I wanted something robust and comfortable. The whole set up of the wheel is of excellent quality, hubs, spokes, rims; and the service from the guys at Cycle Division is as good as you'd wish for. Bottom line. Buy these and I really believe you will not be disappointed. (Posted on 28/08/2017)
Excellent Value & Quality Review by Velodan68
I have now been running these wheels with Conti HP4000S II's for over 500km and am thoroughly impressed. They ride lovely and look great and have a nice sound from the freehub. I highly recommend them at this price. 10/10 (Posted on 15/07/2017)
Trusted others reviews and wasn't disappointed Review by Simon
After my mavic Cosmic Carbones finally died I was faced with a massive bill for same again or opt for shallow rims. A friend recommended these and I took their for for it.

Really impressed with the performance. Much quicker than the Mavics and although braking in the wet is an "experience" I usually ride in the dry. Great looking wheels and make the bike look so much better. (Posted on 15/07/2017)
Great set of Wheels Review by Sheraz
Before talking about the wheelset, I'd like to say that I was a little apprehensive buying from Cycle Division and the CERO wheels; mainly because I'd never heard of neither company before. The wheels were recommended by some forum members as they mentioned CERO wheels were light and good quality. Anyway, I can positively say that I'm glad I bought the wheels and Cycle Division have been top notch with responses and the before/aftersales customer service, especially Ben who has been fantastic all the way through. So anyone in a similar position to where I was a few months ago, you won't go wrong with these guys as the delivery was extremely fast with customer service to match.

Right, the wheelset :-) Overall impressions are very positive. The RC45s are light; lighter than other comparable alternatives @ just under 1500g. The quality is first rate, I had some Chinese clinchers a few years ago, although they were good, the quality and weight on the RC45s is top notch; there is a premium feel about them as the finish is great.

The wheels come carefully packed and included 2 x Conti Race Sport 25mm tyres (nice) plus the spare spokes and carbon brake pads.

I've now done around 500 miles on the wheels; they roll extremely well and do look fantastic. I wouldn't say they are rapid off the line but they are definitely not slow too but once up to speed, you feel the difference. These wheels would make an awesome upgrade to anyone looking into deep rims or looking into a faster lightweight wheelset.

2 things I've been really surprised with (both good):
1) The braking on the wheels is fantastic, much better than I expected. I've not been out in the wet so can't comment on this for dry weather and descending down from hills, the stopping power is great.
2) There is little cross wind effect when it's blowy. I say this because on my previous 50mm clinchers I experienced this quite a bit but so far on the RC45s I've not been pushed about which is very surprising - so a big tick in the box there.

Final point on the summary is how they hold up on the hills . . . simple answer is they are brilliant. Although behaviour of deep rims and lighter wheelset is always different on climbs, the RC45s are keep the speed and roll extremely well when pushed. You will feel more off a difference when rolling on the flats, this is when the wheels really come alive but even on the hills, if you push them, they will hold the speed.

The combination of sub 1500g weight and deep rim makes these wheels a bit of a no brainer; having searched for a few months looking for light but deep rims, the RC45s were standout when you put the price/weight and build together.

All in all, fantastic wheels and I would not hesitate to purchase another set from CD if it comes to it.

Highly recommended guys!

Speed and Style Review by surfboy
I was scepticalbut these beauties are genuinely very quick. In 3 months have now beaten all my previous strava times (and I am not getting any younger!!) - they are the elixirof youth (Posted on 19/05/2017)
Outstanding wheels Review by MikeW
I've had these whels nearly a year now and they have been outstanding. Run really well and remarkably good braking. Faultless and look superb (Posted on 14/04/2017)

Top Quality Wheels Review by SP#46
First set of carbon wheels and I am very happy with these beauties, they also look the part.
Good service from Ben @ Cycledivision.
Braking is fine although cant comment in wet weather.
Wheels are stiff & true, spin up really quickly and roll really well.
They also ascend fine so no problem on climbs.
Why spend 2 times the price of these for some of the bigger "named" brands... GET YOURSELF A SET NOW.... (Posted on 19/06/2016)
Carbon crackers Review by Lincoln Imp
It's taken me about 6 months to do a review as I didn't ride them enough after getting them (in the deal of the year in a flash sale £540 I think) to do a proper review. But after quite a few fair weather rides it's time.

They look fab and ride really well. They just feel fast though it's hard to be sure how much this in just in my head but they seem to spin up to speed really easily and hold their speed better. Braking is fine though I don't know about the wet as they are very much my best wheels for good weather and racing. Nice and light too which for 45mm rims is a real bonus. They are my first carbon wheels so do feel a little harsh compared to my other plusher rims (Pacenti sl23).

Do be aware that these wheels are very wide (28mm at the widest point which is not the actual brake surface) so make sure there is enough room between your chainstays. Mine only just fit. (Posted on 07/06/2016)
Cero RC45 Review by Raul
Bought mine in the black Friday sale.BARGAIN OF THE YEAR ! . Light, fast but the noisy freehub makes it trickier to be stealthy before overtaking ! . But great wheels though. (Posted on 17/04/2016)
