The Continental Grand Prix series of racing clinchers is the top choice of serious race bike specialists all over the world, and has been for many years. The latest incarnation is the Grand Prix 4000S.
"Had the 4000 series for two seasons and was very happy with them..tried the S this time around and there is a slight but noticeable difference over the 4000. they have a lower rolling resistance so fractional time improvements over the 4000. No punctures yet on roads but thankfully only ever got 2 in one year with the previous tyres and the surfaces i cycle on are pretty smooth roads. is it worth the extra few quid? .. to me it is but maybe not to all compared to the standard 4000."
"I suffer from cold feet and tried most products..super warm tech fabrics to marino wool and fabric overshoes (haven't tried neoprene overshoes as i dont like the bulk) , i have also tried layering socks and pretty much the same result.. ice blocks after a race paced cycle in sub 8c weather. Got these a couple of weeks ago and have used them to 5c and i'm very impressed .. no ice blocks and the fabric does block the wind. I reckon these with a fabric overshoe will work well to 2c or 0c but will have to reserve judgement until that weather arrives."
Pros: Comfortable, High Quality, Lightweight, Good Fit
"Bought these after using Sportful body fit pro bibs..have to say these compare quality wise if not better. Great fit and look smart too! I'm a medium and ordered a medium in these which are not as "snug" as Sportful but fitted perfectly."
Pros: Durable, Attractive, Comfortable, High Quality, Good Fit
