2019 Kinetic-One K1-45SL GRAPHITE 45mm deep Alloy wheelset


Product information


INTENDED USE:  Sportives, Bunch races and Triathlons (from Sprint to IRONMAN distance.) This is the 2018 K1-45SL Superlite Alloy wheelset with superb and rather beautiful full black ‘graphite’ (anodised alloy) rims.

Your wheels will be handbuilt to order here in the UK by Andy Morgan, owner and founder of k1 wheels. Turnaround time is 4-7 days!

This is the new Limited edition version of our best selling alloy deep section wheelset! A high-end ALLOY aero wheelset for riders who want all the aero benefit and lightness of carbon - but want to stick with a more robust material.  

Standard setup is with our superb  Italian sealed bearing Ambrosio hubs and high end Belgian Sapim RACE black spokes or Aero and light PSR black spokes. (Choose "PSR1422 Aero" for aero/lightness or choose "Race" for strength). 

We offer various upgrades to spokes and hubs. Contact us if you’re not sure what’s best for you! Upgrades can help you get lighter, get even more aero or add to the lifetime of your wheels.

We also offer 2 spoke count options on this model. 20/24 is fine for most riders up to around the 95 kg mark. But for heavier riders (or those who are tough on their wheels!) we offer a 24/28 spoke super-strong option.

The use of such wonderful components enables us to produce a true "pro-level" multi-functional aero wheelset, at a reachable price point. And Handbuilt in Gloucestershire.

Offered With Full 2 Year Warranty Plus A 14 Day "No Quibble Returns Policy" - If You're Not In Love With These Wheels The Moment You Get Them Just Send Them Back For A Refund Any Time Within 14 Days Of Receipt.

This wheel has a very specific place in our range (and in our hearts!). A super deep-section lightweight alloy wheel is the perfect "do-everything-wheelset" for multi-gradient triathlons, time trials and even sportives. Designed to run best with 25mm or 23mm tyres.

Light enough and comfortable enough to get you up those hills in good shape, (with silky smooth bearings to help even more), and aero enough to gift you free-speed on the flats and the downhills. At the same time these wheels have an additional benefit compared to carbon wheels: Their durability and strength.

Price is for ONE PAIR of wheels - 700c size with clincher rims

I actually have 2 sets of these - one with track hubs for my singlespeed (that Andy built specially for me) and one for my Bianchi with gears. Both sets perform great and look great and I would recommend them. A Kinetic shop in Ireland would do well!

I purchased a set of wheels from you some 3 or 4 months ago. First impression was they looked very good but I wanted to give them a good road testing before I made my mind up about them. I am very pleased to say I think these wheels are great and I have no hesitation in recommending them to a lot of people who have asked me about them.will be coming back to you when they need replacing which I think will be along while off yet.thanks very much Bob G

Service = excellent Delivery = well packaged and when stated The product to look at = wheels look the business! To use = admittedly the previous wheels were bog standard but even still the difference was ammence! More speed everywhere, especially on climbs. Avg speed has increased by 3mph! Went from mid table in competitions on the bike leg to now getting into the top 10 percent. With the old wheels I struggled to roll past 60 mile rides and now I've done 100+ ones. With the exception of my bike (which I won't be sending a pic of as although I love it, looking at your gallery, I would feel bad if I saw a pic of mine!) the single best bit of kit I've brought to improve my tri performance and all round biking satisfaction!

Was looking around for carbon wheels and then I saw these. They did a good selling job with what they wrote as I was a bit nervous about carbon wheel strength anyway - so it touched a nerve. I love these wheels. had them only 2 months so can't comment on long term durability yet - but they are still so true and really feel incredibly strong when riding them over bad roads etc. Bought them to race on but have to say that they are on my bike 24/7 already!

My Sunday best wheels - never let me down - 8 sportives last year and almost most as many training miles as i intended to do. Strong too.
Andrew Butcher - Lyme Regis
My K1 wheels have been everything I could have wished for.I am currently training for a European event from Switzerland to London so have done plenty of miles with no problems.Not surprised that they are their best sellers.

You know you have good wheels when your mates have to pedal down hill to keep up with you...My K1's are excellent.

These are the second pair of wheels from Kinetic One and probably won't be my last! Great value upgrade to my triathlon race bike (the previous set went on my road bike) especially compared to the standard factory wheels that come on the bike when new. The wheels are a great compromise between strength, weight and aero performance. I also find the pricing to be the best value available compared to comparable products. Top it off with a good personal service from Andy it is difficult to find any fault at all.

Hi Andy, the wheels came yesterday and good timing, they are amazing, smashed PB for 10m by over 90 seconds, they just keep spinning so much more efficiently than the standard giant wheels that came with the bike. Seemed to make going uphill easier too. Thanks, Cheers, James

Hello Andy, after a weekend of excessive testing, I am absolutely happy with the wheelset, you have built for me. We had some hard rides with long and steep mountains followed with a certain number of sprints. After using quite a few sets of prebuilt system wheels (Mavic, Fulcrum, Campagnolo), I believe I found the one, that fits all my requirements. Thanks again for building these great wheels for me!
Paul Stretton - Penguin, Tasmania (seriously!)
Wheels arrived yesterday, after a couple of anxious days, Thanks you very much. Put them straight to work today in a local 65 km graded handicap. Dalton (son) finished in the front bunch from C grade with an average speed of 44 kph (27-28 mph) on his restricted u17 gearing. It was an extremely fast race today, and I was pleasantly suprised to see him still in the train that rolled over my lowly E grade bunch with 5 km to go. The only other junior to finish with the front group on the day was running unrestricted gearing. We are both extremely happy with the way the wheels preformed today. They certainly raised quite a few eybrows from the other juniors, most assuming he was running carbons. Will shoot you an update along with some photos after our nationals trip
