For nearly 100 years, Italy-based Ambrosio has quietly been producing some of the finest hoops to grace race bikes ridden across the roughest roads that Europe could muster. Even at the behest of sponsorship obligations, champions like Hinault, Lemond, Bettini, Armstrong, and Boonen have long been known for their insistence on Ambrosio hoops for their legendary durability and ride quality. The Nemesis Tubular is Ambrosio's top-shelf alloy tubular rim and a perennial favorite at Paris-Roubaix, where a quick perusal amongst the ranks on race day reveals plenty of rebadged rim sidewalls, but the tell-tale Ambrosio valve badge still says it all.

The sturdy 13mm deep box profile of the Nemesis measures 21mm across, making it perfect for fitment with your favorite 23 or even 28mm tubular tire. It is available in a 32-hole drilling, with double Inox eyelets to reinforce each spoke joint. And it wouldn't be an Ambrosio without a stealthy hard anodized finish that resists brake track wear, which, we might add looks exponentially more awesome after splashed with Belgian mud. At only 430 grams for the hoop, when paired with a lightweight and durable hub, you can expect a lifetime of fast-rolling reliability for cyclocross, year-round training, or for simply drilling it across those gravel parcours that punctuate your weekly bully ride.

I suppose nearly all has been said about these classic rims elsewhere online. Nonetheless, I will share my experiences. Also, these rims deserve more attention than only one review at

Years ago I raced a pair of Nemesis + 10-speed Chris King R45 wheels for two seasons. I enjoyed those wheels until an unfortunate crash irreparably damaged the front rim and really abraded the brake track of the rear rim.

While my friends replaced their alloy rims with carbon fiber ones even for training, I charged ahead with a variety of aluminum hoops - HED C2 Belgium, Velocity Pro Elite (tubular), Campagnolo Shamal Ultra, FSA Team Issue, H Plus Son SL42, Mavic Open Pro, Fulcrum Racing Zero (tubular) and HED Belgium Plus - with one exception. After my aforementioned crash, I rode ENVE 65 tubular rims. After wearing out one set of tires, I retired the ENVE wheels because I was not impressed. Did I enjoy the aerodynamics? Did I enjoy the quick acceleration? Did I enjoy the impressive sound of speed ("whoosh, whoosh, whoosh ..."). Of course, I did, but ride quality was noticeably absent.

While 32-hole, 3-cross front and rear wheels are excessive for most of my road-riding friends, such wheels have performed well for me year after year since I am a heavy rider (who is too sensitive to label himself as a "fat cyclist"). (Plus, that title is already taken.) I kept thinking about my Nemesis rims and how much I preferred the ride quality and strength of those box-section tubulars. I descended canyons better with those rims. I did not worry about unpaved roads. People reminded me how classic they looked. I remembered sprinting better. I actually won a race with those wheels. Among the wheels I listed above, my Nemesis + R45 wheels were my favorite. So ...

I now have two pairs eagerly waiting for hubs. Storage seems to have tarnished the valve badges of one set from gold to orange. So I intend to match this pair with orange CK R45 Disc hubs for an upcoming 'cross bike.

Even as tubeless tires challenge the efficiency, souplesse and cost of tubular tires, there are still reasons to buy Ambrosio Nemesis rims. They continue to perform better than modern, much more expensive options. They are classic; they have a legendary history connected to the Spring Classics. The Nemesis rim is an example of something great that is overlooked because it is old. These rims are still great. They are old because they have been great for so many years for so many riders. Don't ignore them. Buy them. Ride them. Every cyclist should experience these rims, which is why I will be gifting my second pair to a naysayer.

Well put sir. I have a pair with DA hubs. Really hard to beat.

I couldn't agree more. My Nemesis are my daily training wheels. They ride like Cadillac - heavy, smooth, and with confidence. Enough with the carbon clincher fad, and the 'tweener light weight clinchers. Nemesis are a ride quality rivaled by no other.
