Bike reveal - Kuota Kharma Race Carbon Road Bike

Not everybody has the cash to buy the Tour de France wonder machines on the market. More habitancy are looking for a good value in a high operation carbon road bike. This is where bikes like the Kuota Kharma Race come in. Many of the features of the higher end models with a much more modest price tag. Four years ago a frame like this would have been on a 00 bike. Now the faultless bike is less than half of that.

[b]Bike Review[/b]

The Kharma Race is ready as a faultless bike or frameset to build how you like. The faultless bikes are ready with Shimano 105 or Ultegra, or Sram Rival. I tested the Rival equipped bike. While a recapitulate of the group will be for an additional one article, it works flawlessly. Shifts are fast and literal, with a good lever feel.

The heart of any bike is the frame and what a heart the Kharma Race has. The swooping curve of the top tube draws the eye to the aero seat cluster. All the tubes flow into one another. Unusual for a bike of this price, the frame tubes are aerodynamically optimized to help you cut through the wind. This includes a cut out for the rear wheel in the seat tube and an airfoil shaped seat post. As wind drag accounts for over 90 percent of the resistance when riding on level terrain, every miniature bit helps. The fit is a miniature more relaxed than it's higher end siblings, with a slightly shorter top tube for a given size All of the tubes are shaped to give a good equilibrium between aerodynamics, stiffness and weight. And being an Italian design, a distinct flare is apparent that you don't see from a lot of the big brands. You will stand out on the local group ride on a Kuota Kharma, as they aren't the thorough cookie cutter bike.

But that is just the construction. The ride quality is the real star of the show. When I stated earlier that this would have been a top of the line frame a few years ago, I wasn't exaggerating. I used to ride the Orbea Orca and that is what this bike reminds me of. Stiff but not harsh. Light and responsive. Handling is quick but not twitchy. Just very well equilibrium with a good road feel. When you jump out of the saddle to sprint or climb a hill, the power is driven to the rear wheel. This doesn't ride like a company's starter carbon fiber bike. If you put on a set of race wheels on, you will be able to contest any ride or race you have the legs for.

The build kit that comes with the bike is solid with Deda bar and stem, Selle San Marco Ponza saddle and Shimano R-500 wheels. You may find the need to swap cockpit parts as the fit of these won't be for everyone, but is usual with any bike. The only area I would recommend upgrading if you want to race or just get maximum speed, is the wheels. The Shimano wheels are fine as a training wheel but the aren't either light or aero enough for a race wheel. If you haven't ridden deep carbon fiber rimmed wheels then you won't find it an issue.

The Kharma Race fits my criteria of being a working class bike. It's light but tough. Good value with operation well above it's price tag.

Kuota K - Factor Carbon Triathlon Bike describe

Triathlon bikes are a limited different from road race bikes. The most noticeable is the aero bars and wing shaped tubes but the frame geometry is different as well. The frame geometry is optimized for riding in the aerobar position to minimize wind drag. In triathlons you aren't allowed to draft off other riders so everything about the bike is aimed at reducing aerodynamic drag. By reducing the wind drag you are going to be faster for what ever estimate of power you are able to put out.

[b]Bike Review[/b]

The K-Factor is the entry level carbon fiber tri bike from Kuota.The geometry will fit a broad range of people, especially those of us over 35. For a given size the head tube is a limited longer than the other models in the line-up allowing for a more comfortable fit, especially for Ironman distance events. Compared to the more aggressive bikes on the market, you won't end up with a huge stack of spacers or high angle stem to get the bar high enough. As well, tubes are a limited beefier so you will find a lot best endurance in the long run. It's still very light but more attention has been paid to aerodynamics. And because they aren't pushing the weight envelope the price is quite reasonable.

This Italian designed bike looks fast, with a deep aero fork and air foil shaped frame tubes to help you slice straight through the wind. The rear wheel spacing is adjustable allowing you to get the wheel tucked into the frame again for smoother airflow. The seat tube and seat post have an air foil profile to further decrease drag. All of this may seem to be over kill but above 27 km per hour over 90 percent of the drag you have to over come is air.

The handling is pretty stable for a triathlon bike but it isn't a lazy touring bike by any means. everything about the K-Factor is built for speed. This is a bike that loves to go fast. Your power makes it to the rear wheel without loss due to frame flex. It climbs well but is best on flat to rolling terrain where the aerodynamics precisely come into play.

You can get it with many build kits. I would propose getting it with a basic set of aluminum training wheels and get a set of deep carbon wheels when your allocation permits. And because the Kuota K-Factor is many thousands less than a lot of the triathlon options you will have the money for your race wheels much sooner.
