Kestrel 4000 LTD di2 Review

Kestrel 4000 lands in the market after many hours of testing in the A2 wind tunnel. Throughout the process of manufacturing special attention is paid to rider comfort. In the latest designs a bit of suspension is added to the seat tube. The Kestrel 4000 LTD di2 is super fast and comfortable. No matter how tough a route you select to cycle, the Kestrel 4000 meets up to your expectations.

A brief description of the Kestrel 4000 LTD di2:

• Fork: Ems Pro TT Carbon Steerer 1 1/8”
• Shifters: DA 7971 Electronic
• Frame: 800K High Modulus Carbon Fibre with replaceable or adjustable dropouts.
• Chainset: Vision Trimax Pro Aluminum TT 52/38T
• Caliper brake system
• Gel padding in the grips

Please take special care while you work on tightening the attachments on to the carbon fiber frame. The frame is a bit sensitive, and it is highly likely to get warped. Please don’t forget to check your bike after some twisting motion and excessive force are applied on it. You should keep in mind that the carbon fiber is lightweight yet durable and strong, but still it is not unbreakable. That’s why you should keep looking out for signs of damage on the frame before you plan a long and strenuous tour.

The Materials

Carbon fiber is not a cheap material. It is more expensive than aluminum. More and more bike manufacturers are now using it. It is one of the lightest materials available to make bikes. It is even lighter than aluminum by a few pounds. The price tag is no doubt a bit high but considering its benefits it is nothing. Carbon fiber frames are stiff that’s why they can bear a few impacts. One negative point is that carbon fiber is brittle that’s why it is not too trustable for a mountain ride. Moreover if a metal bends, you can get it straightened in a fair price but as carbon fiber is brittle, cost of its repairing is a bit high.

What It’s Good For

Kestrel 4000 LTD Di2 is the best for your cycling tours. Fitness enthusiasts love this bike. The rigid frame as well as rigid forks have lifetime warranty. The rest of the bicycle parts are on one to five years warranty. But the bike must be assembled by an authorized Kestrel dealer if you want to have a valid warranty.

One feature I love of the Kestrel bicycles is that they accommodate triathlon position. The top tubes are fairly long while head tubes are fairly short. Riders who have short legs and a long torso really appreciate it. Kestrel 4000 LTD Di2 has very finely tuned airfoil profile. Its tubes are shaped like wings. The seat tube is so small that it seems to be disappearing. It has a super structure. Its razor-like deep section Oval Concepts carbon wheels along with Vittoria Open tires make it super fast. Gears change at a press of the button. The Oval Concepts carbon aero bars and the triathlon seat help the riders achieve the aero tuck. All these features are combined in your Kestrel 4000 LTD Di2 bike. It is completely reliable for a fast, safe and smooth ride. Turn your weekend tours into adventures. Let’s take a look at its pros and cons.
