Tire Evaluation – Continental Grand Prix Attack II

The Continental Grand Prix Attack II is your leading tire of the Grand Prix Attack II/Force II street Collection. Its bigger 22C size must supply an aerodynamic edge when used as a front bicycle while the marginally bigger 24C Force II provides enhanced comfort and traction as a back tire. These two tires are extremely closely associated with the popular Grand Prix 4000S II since they utilize the exact same 3/330 casing and Dark Chili compound.

As I’ve already mentioned at the GP Force II (inspection), it is important to contemplate rim width also in the event that you would like to acquire an aerodynamic edge from the smaller front tire. Only mounting a bicycle that is smaller to a rim that’s been aerodynamically optimized for use with a larger tire is not likely to give you an benefit. When you are going through all of the trouble to obtain those last few tenths, then you need to use a bigger rim on the front wheel too.

All rolling resistance evaluations are conducted on our rolling resistance test system. Read our The Evaluation page for a detailed explanation about how we examine tires.

Do not forget to have a look at the review pages to make it simpler to compare all of tires which were examined.

The specified weight of this 22C Grand Prix Attack is a reduced 175 g. My sample came in at 182 g. The measured diameter and elevation onto a 17C rim, in an air pressure of 100 psi is 24 mm and 21 mm respectively. The sizing seems to be in accord with another Conti tires that largely arrive in 1-2 mm wider than defined in my rim/air pressure.

The entire depth of the scooter in the middle of the tread comes in at 2.2 mm that’s marginally less than the GP Force that came in at 2.3 mm. 2.2 mm is about the thin side to get a street bike scooter as most all-round tires appear to come just shy of 3 mm while the no-compromise time-trial tires come in closer to two mm. The GP Attack/Force certainly will not come close to the mileage that a GP 4000S II provides. More details about bike pumps can be found at vibrelli bike pump.

*Please be aware that I typically examine 24/25C tires that have a larger volume compared to 22C Attack. As all evaluations are done in precisely the exact same air pressures to make it simpler to compare all of information side by side, actual rolling resistance of these smaller tires will probably be marginally better since you are able to run a greater pressure for the identical comfort level.

At very large air pressures, rolling resistance from this Strike II is a bit greater compared to Force II 24C, however lesser compared to GP4000S II 25C (read review). When falling air pressures, rolling resistance begins to go up quicker than most other tires that may result from the decrease quantity. Like previously noticed, the 22C Strike is the smallest sized scooter on this site so it will be more difficult to compare to the remaining tires. In general, rolling resistance seems to be somewhat higher compared to GP Force.

From the puncture resistance evaluations, the GP Attack works both in both the tread and sidewall evaluations. Having a score of 9 points at the tread evaluation, both the Strike and Force provide less puncture resistance compared to favorite GP4000S II that came in at 11 points.

In general, rolling resistance of the Grand Prix Attack is marginally higher when compared to the Grand Prix Force while supplying the same tread depth and puncture resistance. When compared with this Grand Prix 4000S II (read review) or Grand Prix TT (read review), the Strike does not seem to provide any benefits. Remember to use a wheel optimized for 22C tires on the front plus a wheel optimized for 24C tires at the trunk if you are seeking to obtain an aerodynamic edge from a more compact front tire.

I speed the Force/Attack front/rear combo 4 out of 5 since most people have exactly the exact same diameter rims front/rear that will ensure it is difficult to acquire an aerodynamic edge from such tires. Additionally, opting for a 23C/25C Grand Prix TT combo can provide you the exact same advantage whilst supplying a substantially lower rolling resistance.
