The Fulcrum Racing Zero C17 is a best-in-class alloy clincher road wheelset that balances lightweight, durability and performance exceptionally well. While this wheelset feels fast and responsive out on the road, weighing just 1495 grams, thanks to the triple-milled rim construction they still boast class-leading strength and durability.
The slight difference in depth between the front and rear rim helps to reduce system weight and increases the lateral stiffness of the rear wheel, helping to deliver power directly from rider to road. With a rim diameter of 22.5mm, the Fulcrum Racing Zero C17 can accommodate tyres up to 50mm, increasing grip and rider comfort across rougher surfaces.
The front hub shell is constructed from carbon to reduce system weight, while the high-flange rear hub is made of alloy to increase torsional stiffness. Both hubs have proprietary USB bearing internals, which promise a reduction in rolling resistance and increased durability. These high-quality hubs are laced to the rims via 16 bladed alloy spokes on the front, and 21 on the rear which maximises aerodynamic performance and wheel strength. As an added bonus, these alloy spokes are easy and economical to replace should any unforeseen potholes cause any damage. In all, a lightweight alloy wheelset that is equally at home on fast flat group rides, as well as steep alpine climbs.

Very happy with wheel set. They meet or exceed my expectations. My original order was lost by the courier, however, Probikekit shipped a replacement set. I will be a customer for life.
These wheels made a huge difference on my 2012 Giant Avail Advanced 0 W. I decided to finally upgrade the stock wheels, and I am glad I did. I am starting riding again after several years. I started back up five weeks ago, and I was able to shave off one mile per hour on my first ride on these wheels today! The value was great for this wheel set. I couldn’t find any aluminum wheel sets here in the United States. The shipping was fast as lightening! Just be forewarned, you will have to pay duty and taxes after you receive your wheels. These wheels are worth every penny!
greatest wheels ever
I had a set of ceramic bearing wheels before. These wheels are even better. I picked up three more miles an hour with these wheels. Also I have a set of carbon wheels, which I have had problems with side winds. With these wheels there is no effect with stability. The side load is zero. Great workmanship, plus it is a lighter wheel. I'M age 74 and need all the help I can get , these wheels give me that extra push.
After ordering the notification email stated 14 day delivery. The rims arrived after only 5 days. So happy! I noticed an immediate difference. Better handling and extremely improved power transfer for acceleration and climbing. Very happy with these rims.
A Gift From the Cycling Gods
I have been riding on Fulcrum wheels for years now, and have never had a complaint. My better half gifted these to me as a well deserved, although not needed, upgrade. My old wheelset was a pair of Fulcrum Racing Quattro that are still very much in use depending on my ride plan. I am ever grateful!!! They are quiet, smooth, fast and responsive. I paired these with my first ever Schwalbe tires and I undertook some component maintenance for a strong supporting cast for these new stars to the show. (New front chainrings, chain, brake and shifter cables/housings and of course they got a brand new cassette.) Like a new bike? Certainly. These Racing Zeros are super quiet. The freewheel is like a ninja. My Quattros were never noisy, but the Zeros are just noticeably absent of sound. It took a touch of getting used to, initially. The brake pad rim engagement is also super quiet also; but there is no delay in deceleration or stopping. Oh what a joy they are! You know that feeling of being able to pedal forever? These babies will coax you into PR after PR. The spin up real nice and the hubs just want to spin/roll forever! It's like butter, baby... Upgrading in the same line has proven to be wonderfully informative and I love the Fulcrum brand. This Fulcrum Racing Zero wheelset is well worth the price. If the addage that a wheelset is the best dollar for dollar upgrade on a rig, than I thin these are definitely worth your consideration. 5 stars in every way! Safe riding!!!
These wheels are a replacement for the stock Roval wheels which came on my 2012 Tarmac, apparently an equivalent replacement by some experts. The Rovals needed replacement due to rim split at the spokes, 4 to be precise. After 15K kilometers I'm told this is to be expected. So after 1500kms on these new wheels I have to say that I am quite pleased, they feel light and with that comes responsiveness on attacks up the hills. They do catch the cross wind more than my old wheels but that is probably due to the wider flat spokes compared to my round ones on the Roval. Possibly these same flat spokes make headwinds easier. The rim brakes are sure, no excessive noise here. They expect 25mm tyres but I have some new 23mm which I need to use and I placed that in front and have not had any worry. I would recommend these to a friend.
Great wheels. Smooth. Accelerate well. Bought these to ride the winter. Have a set of envys that I love. These wheels are close. I have other sets of aluminum wheels and these are better. I can’t believe how much I like these wheels.
The Best of the Best
The racing zero alloy clincher is the top of the line in its category for good reason. These are both lightweight and bombproof, two things that normally do not go together in cycling. The C17 rim accommodates today's wider tires - I'm running 28's and it rides wonderfully - smooth yet stiff. The ceramic bearings were immediately noticeable to me for their smoothness. Taking the stickers off the rims is a chore but the clean solid black rim is worth the effort. A note of caution - the adhesive remover I used accidentally erased the small warranty sticker that is required to remain on...oops. The good news is I have ridden Fulcrums for many years and never had a warranty issue. These replace a set of the Racing 4s and the upgrade was well worth it.
These things just want to roll.
First wheel upgrade from a set of Shimano WH-R550 wheels. The Shimanos were not bad and gave years of trouble free service, but the difference with the Fulcrums is immediately apparent. As a wheel rookie I don't know about the technical aspects, but I do know that these wheels will put a smile on your face and make you want to get up early and ride. 100% satisfied. For other wheel rookies- the polished silver spots and small bits of tape on the inside of wheel are normal.
Had the narrower version of these a few years ago and when needed some alloys for the good bike these were first choice. Spin forever with the ceramic hub. Light, look great. Zero negatives. Even got free tyres! Fast delivery too, so top marks for probikekit too
