The Calypso K tires are constructed with a 220 tpi polyester-cotton casing with Kevlar belting for incredibly supple but durable ride. Opposing file tread on a 3D compound makes for perfect adhesion to the road that the Gommitalia is known for.
Like most clincher tires designed in Italy, they have that super supple casing and soft rubber that gives them the "Open Tubular" feel on the road. A tire that rides this nice will not last forever like a high mileage training tires. However, if superb ride quality and grip is at the top of your priority list for a tire, the Calypso K could be the tire you are looking for.
As with any tire, do you want mileage or performance? If youre looking to get 3,000 miles out of one of these (especially on the rear), youll be disappointed. If you want the ability to ride through a field of thorns & broken glass like you have Gatorskins, youll be disappointed. HOWEVER... If you want a ride that feels close to a tubular at less than half the price and want the ability to almost drag a knee in corners, then you will love this tire! I am addicted to cornering fast, and these are noticeably better than, say, Contis (not that I dislike Contis at all). I usually go through 3 Gommitalia rears for every front, and a rear tire only lasts me about 1000 miles. So for me spending $40 every 1000 miles for superior ride and grip is worth more than spending $70 every 2000 miles for another tire. Your mileage may vary (pun intended!)
Bought 2 pair. The first pair had an incredible ride. As good as a good pair of sew-ups. They did get a few punctures though, and I rarely get punctures. I put the second pair away, as I was unsure of their durability. After a couple of years, I needed some tires and went ahead and put them on. Incredible ride, once again! This set has been in use for over a year without a single puncture. Im hooked now! Great tire, with the best ride for a clincher that Ive found.
I got myself four of these, two red and two yellow, way back when the price was even lower :> The average weight of these four tires is 238.5g, ranging from 234g to 241g. Ive been using the yellow pair since. No complaints about traction, and so far no punctures. However, my rear tire suffered a sidewall cut of about 1cm, probably while riding past a sharp object (discovered the cut after finishing the ride) . The tire was pretty new and I had no heart to throw it away. Managed to seal the thread portion of the cut with CA glue, and I used a short strip of cotton cloth glued to the inside of the sidewall with Shoe Goo. So far Ive manged to keep riding this tire and the cut has not gotten any bigger (keep checking before each ride). Before applying any glue to the tire, always scrub the area thoroughly with soap to remove any mold-release coating, or your glue wont hold. After the cut, I now inflate at 100psi (cut tire, in front), 105psi rear. good enough for my 60
Very impressed for the price. No issues with them and they corner and wear well. Will get another set.
On my 2nd set of Calypso. Rear on 1st set lasted almost 1900 before outer rubber delaminated from Kevlar belt. 2nd set rear now @ 1700 and tread is almost used up. These tires feel light, responsive and have very good grip. And at 220 lb this tire shows excellent durability.
Never again. I rode these for a few months in NYC and SoCal in all sorts of weather and road conditions. They look great (red) and have a very comfy road feel as long as its straight, dry, and clean. The very first corner with fine grit and sand I took at a moderate non-race speed (and had ridden hundreds of times before) scared the crap out of me and I should have stopped using them immediately. It was the first time Id felt BOTH TIRES lose lateral grip with no warning and I assumed it was a result of residue from the manufacturing process. I scrubbed them when I got home. These have a fine herringbone tread which I now understand slides laterally over grit, sand, and water whereas a slick tread (as Sheldon Brown has documented - well worth reading) will maintain more traction. Last Nov. these provided no feedback other than a brief shush sound as they slid from under me and contributed to the first ever crash and broken clavicle (+2 ribs) Ive had in many many years and
I cant believe the reviewer, below, who claims the tires give a harsh ride on his Trek cf bike. Id like to know his frame of reference. The Calypso K tires are noticeably smoother than any clincher I have ridden, including Schwalbe Ultremo, Michelin Pro2Race, etc. Very grippy, too. Time will tell on durability, but so far I like these tires very much.
I bought these tires from Excelsports in September and I have put tons of miles on them here in Phoenix, AZ and they are very durable. Additionally, they ride extremely well, cornering well. They are very light at only 200 grams and high tpi makes them supple. I highly recommend them and use them on my Colnago C-50.
These tires are awesome! They offer a very supple ride and are fairly light but still have the durability to hold up to training and racing. The set Im riding now has well over 2000 miles on them. I found if you rotate when you start noticing wear on rear that they last a long time. These have to be one of the best values around.
Ride Quality: Outstanding for a fast training/racing tire. When inflated to max pressure, these are hard tires. They are also very quick. Confident cornering. Construction: Nice quality. Go on pretty easy. Very durable tread is still soft and stays remarkably clean on gravely roads. Casing is tough for a light tire. Profile is round with light tread in the Italian style to give a smooth ride. Overall: Bargain tire set that I will continue buying as long as available. Excellent for broad range of road riding. Graphics are well styled, not loud.
Using the Calypsos on a Trek carbon fiber frame. They are reliable, safe, and cheap. Unfortunately they are also stiff and uncomfortable. Their stiff ride undoubtedly means they are slow and that is my subjective impression also. Tires as stiff as this slows a bike by translating forward motion into vertical motion. Theyre coming off the bike asap. Note that the carbon frame is a pretty comfortable bike, the Calypsos make it feel otherwise. The price is good, but not worth the negatives.
Exceptional value! The 220 tpi casing makes for a supple, controlled ride. IMHO much better than tires costing twice the price. I have 9 vintage lugged steel bikes & 1 brandnew, high- end full carbon ride. They all have Gommitalia Calypsos.
Best. Tire. Ever. I cant believe how good these tires are. Nevermind that theyre so darned cheap. These tires are the best clincher tires I have ever ridden. They are far nicer than the would-be race tires that I paid twice as much for. Some random points that might sway you to buy tons of these tires and stockpile them for the rest of your riding life: - These tires go on very easily. I have mounted them without aid of tire lever. The bead is easy to work, but is firm enough that the tube doesnt come squishing out when inflating the tire from empty. - The manufacturing quality seems very high. Unlike other inexpensive tires, the lines and treads are straight and consistent over the whole tire. - I used to sneer at the idea that a bicycle tire could be supple. These tires are indeed supple. Incredible. These tires are fast. These tires have a great road feel. Im amazed how well they can tackle all three of those sometimes-conflicting jobs.
Best value Ive found. Ive used at least 5 pairs. Ive also used Rubino Pros and 1 pair of Open Corsas. For the money, I prefer these. The light colored ones get pretty dirty looking after a few months. I used to clean them in the tub, but now I just get the all black. They seem to wear very well. I usually have replaced them due to cuts, e.g., in the sidewall that make me nervous, rather than wear. If it massages your identity, get some expensive tires, if you like a good tire for a great price, get these. Geeze, you get kevlar beaded and a belted dirt cheap. Gommitalia is a cool name too.
For the limited miles I have put on these tires, they seem to handle well for a training tire and are nice riding. However, with only about 120 miles on the pair, the rear tire developed a bulge/bubble that is about 1/2 on the sidewall and 1/2 under the tread. I did not hit or roll over anything that should have caused this, nor did I over inflate. I have a replacement on the way in the hopes that it was just one of those rare things because I have read good reviews about this and most Gommitalia tires. If not, Ill go back to Vittoria.
Great tire! These have just as good (if not better) rolling resistance and feel as my Tufo S22 tubulars, but the durability is multitudes better (running Vittoria UltraLite tubes). At just under 1k miles they are wearing excellent through all types of road conditions (even some gravel/dirt). Wet cornering is not quite as good as my tubulars, but I still dont hesitate to ride them in the rain.
Great value. Lively ride -- Ive never been on Conti 4000s, but I find these more supple and more durable than 3000s. Highly recommended. Excel, please continue to stock these, and Ill continue to order them. By the way, theyre light, too.
Ive run threee or four pairs of these tires, I like them very much, and Im glad that theres a "classic"-looking tire available. A MUCH tougher substitute for the old Vittoria Opens -- these do not suffer tread cuts the way my Vittorias always did. I find them to be durable. They are almost as supple as the Vittorias. Im about to order another pair.
The only true race tire available at this price. Close to tubular ride quality. Wear only so-so but this is to be expected considering the weight. Only real ccomplaint is that the sidewalls tend to stain very easily, especially after a rain ride or two.
Surprisingly supple ride, especially at this price. Good wear and puncture-resistance. Will definitely buy another pair.
Better than expected. Has worn well as a training tire. Sheds rocks and debris well. Kevlar belt protects it but the tire still has a pretty good feel to it. Comfortable when pumped to full pressure. Not as quick as Michelin Pros, but last longer (naturally). These are a good early season racing tire. In a pinch, these tires fit both bills. Ill get them again. And the yellow looks really good, too.
Great tire for racing or training, regardless of price
