Many upgrade wheels for performance. Those unable to drop thousands on a set may consider new tires. Stock tires work well when getting into the sport, but performance tires can improve the overall experience thanks to lighter weight, grippier rubber compounds, or improved puncture protection. Introduced last year, the updated Continental GP Force and Attack tires are one such upgrade to consider.

They’re a unique offering from the German manufacturer because they’re available in a bundle or individually. Also, the updated size selection for the bundle is limited to one offering of 700 x 23 [GP Attack] – 25 [GP Force]. Compared to the stock Mavic Yksion Elite tires I was running, I lost 35g of rotational weight and gained a lot more confidence around fast corners and climbs. Read on past the break…



One of the more interesting features of this set is their TirePositioning System [TPS] which takes inspiration from motorcycles. They use a 700 x 23 front tire and 700 x 25 rear to achieve faster handling upfront and a smoother ride out back. Their BlackChili compound gives the tires the grip they need, while their Vectran Breaker builds flat protection into the casing. The folding set has a TPI of 3/330 (110 tpi casing overlapped three times).


The characteristic that has stood out most is the cornering. One of my favorite descents features an ‘S’ turn mid way through, and if the apex is hit perfectly riders go through a seesaw motion from one corner to the next. The tires grip better than glue during similar maneuvers, and sustain it throughout the ride. However, for me they aren’t the most supple or comfortable tires out there. Weighing 180lbs, I varied the tire pressures within their recommended range of 110 – 120 psi hoping to find a softer ride. They were better at 110 psi, but there are other options I would consider if looking for a smoother tire. Recently, I’ve kept the pressure around 118 in the front and 116 in the back which is a happy medium for me. Debris covered road shoulders had me worried about flats, but after months of riding I’ve been in the clear (knock on wood) likely thanks to the Vectran Breaker and good line choice (luck).

I’ve gotta hand it to Continental for beating their claimed weight by 15g. The received set weighs 385g total, with the GP Attack at 168g (F) and the Force at 217g (R). Actual widths on 17mm (internal width) rims were 25mm (Attack) and 27mm (Force), which is good considering trends are moving toward wider tires anyway. For an upgrade that improves weight, traction, control, and speed, the $150 Continental GP Attack and Force set are a solid option to consider. Otherwise, they’re individually priced at $75 for single tire replacement or to mix and match.


  1. For comfort without compromise control, what you need to upgrade is your rim internal width, not your tire width.

    With narrow internal rim, your big tire will either feel squishy in corner because of tire were pushed to the side or need to run higher pressure than necessary.

    Wide internal rim width’s stability really give you ability to run lower pressure with reduced tire deformation in corner, rolling resistance (check it out) and also reduced chance of pinch flat.
    On my 21mm internal width rim (28mm external) 25c up front at 65psi feel about right (25c tire on rim this big become 28-29.5mm anyway). 23c up front at 70-75psi is also good (Conti 4000sii 23c run 27.3mm on my 21mm innerwidth rim).

    I tried to do the same on rim with internal width of 17.5mm but it really need 15+ psi more to feel right for 23c and about 20+ psi more to feel right in corner on 25c. The difference is really that big.

  2. Those tyre pressures you’re using are way too high if comfort is what you are after. Not to mention, these tyres aren’t supposed to be comfortable. They are Continental’s all out speed tyre, mostly for time trials. Anyway, I’ve always found comfort and Continental don’t fit in the same sentence. Unlike comfort and Vittoria or Schwalbe.

  3. If these are not tubeless compatible, they are worthless. to me. Around here thorns and glass shards had us fixing flats regularly even with the excellent GP4000s we rode for years. But with tubeless tires and a dash of sealant, can’t remember the last flat that required installing a tube.

      • This is why I haven’t purchased a new continental tire in a long time, despite really loving the GP4000Sii and GP 4 Season. Tubeless is just so much better for both commuting and racing (once you get used to the install/re-up sealant procedure).

  4. They might make sense if nothing wider will fit, but if you’re not riding a TT or tri bike it’s hard to think of a good reason to buy a 23.
    I went from narrow rims with 23s to wider rims with 25s and then 28s. I’m not going back.

  5. I might be the odd one out on here but I love the conti tires with latex tubes. I wish their publicly available tubulars were as good as their clinchers. I also wish they didn’t update the supersonic clincher. However I’ve been very happy with the “old” 22/24mm attack and force combo. I see no reason that the 23/25mm version shouldn’t be just as great (with maybe a little lower crr).

  6. 28mm – That’s narrow! Try 37mm Compass tires – I’m becoming addicted to them – roll over anything!

  7. Aside from being able to buy the matched set, what separates these from the road-race favorite GP4000SII? It sounds like this has been nearly touched on in the comments already (TT-focused tire) but I’m still a little unclear.

    • They are very similar to the 4000S II’s, but the tread patterning is different, and they market them as a set, so you will place a larger tire on the rear and the more aero 23 on the front. You would be fine just buying a 23 and a 25 4000S II. You’d get basically the same benefits. Or, if you are really concerned with rolling resistance and weight, you could just move to the Conti TT tire or Supersonic.

  8. Conti TT is faster with no puncture resistance.
    Conti 4000sII is thick, heavier but with puncture resistance layer.
    Attack&Force is quite thin so it’ll wear down faster than 4000sII but faster and lighter yet still maintain puncture resistance layer.

    So it’s middle ground between 4000sII and TT then.
