Would you have a look if you can find the information again? ps: The answers on the related question: "What road bike tire pressure is best for speed?" bicycles.stackexchange.com/questions/5546/… Do not reflect the new information (eg wide, supple tires, lower rolling resistance; wider more aero rims availabe) any more. | |

| Dec 11, 2014 at 23:59 | comment | added | Rider_X | @DanielRHicks - You are likely over inflating your tires. 100 psi for 700x35c would be optimal for loads well over over 150 lbs per wheel! See bikequarterly.com/images/TireDrop.pdf - This could make your ride excessively harsh. | |
| Dec 11, 2014 at 23:55 | comment | added | Rider_X | @Trengot - The larger volume means you can run a lower pressure and get the same contact patch size. Larger volume tires need less pressure. Lower pressure also means more suspension, which can be faster on rougher roads. My 700x35 at 75 psi (15% sag) are much faster over B roads than 700 x23 at 110 psi. The difference is measurable and repeatable. | |

| Dec 11, 2014 at 12:58 | comment | added | Daniel R Hicks | @Trengot - I run my 35mm tires at 100psi. Most people seriously underinflate their tires, from the standpoint of rolling resistance. | |
| Dec 11, 2014 at 11:09 | comment | added | Holloway | @DanielRHicks the problem with wider tyres isn't the size, it's that they can't take the same pressure. A 30mm tyre won't hold the same 120psi as 23mm tyres. | |

| Dec 10, 2014 at 23:40 | comment | added | mattnz | On the shortest ride how much is gravel? How much hillier and windy are the gravel roads compared to the main roads. Straight gravel roads will hit speed a little bit, windy roads a lot more). You would need to gain 20% more speed on the sealed road to make up the distance, I find I loose about 5-10% on my MTB on straight gravel compared to sealed roads, however recently graded roads can knock speed by 50%. | |
| Dec 10, 2014 at 22:34 | comment | added | Daniel R Hicks | @OblTobl - Tire pressure is a more significant determiner of rolling resistance than tire width. Running 25-30mm tires will not significantly slow a bike. | |

| Dec 10, 2014 at 14:31 | comment | added | Obl Tobl | @DanielRHicks but that would also mean, that the "road bike" loses much of it's speed if it has other tires, no? And then it's really the question if there are advantages (especially in speed) compared to a cx. | |
| Dec 10, 2014 at 14:28 | comment | added | Daniel R Hicks | Yeah, a "road bike" (not a racer) with reasonable tires can handle a modicum of gravel and can certainly handle some rough pavement. | |
| Dec 10, 2014 at 14:05 | comment | added | Batman | Just because a bike is marketed as a "road bike" doesn't mean that it can't handle a bit of gravel, esp. if it has at least 700x28 tires (though a CX bike would likely be better at it). As for component trim, even the lower end stuff (e.g. Sora) is quite good these days and are a bit less flash than 105; as usual, you need to set them up properly in either case. | |

| Dec 10, 2014 at 11:19 | comment | added | PeteH | Sounds like whatever you decide you won't go too far wrong. 105 is a good groupset too. Depending upon the frame (geometry, material....cost!) of the road bike you might not find it is that much quicker than cx | |
| Dec 10, 2014 at 10:54 | comment | added | Obl Tobl | @PeteH No that absolutely won't bother me. I also have a Mountainbike for 'heavier missions' ;-) I need a reliable bike, so i thougt about Shimano 105 components. But i don't have a favourite model or something. | |
| Dec 10, 2014 at 10:39 | comment | added | PeteH | Yeah, it is difficult to come up with absolutes here. I think a lot would depend on what road bike you're thinking about. One thing I would say is that if you do go down a "road" route, you're not really going to be suited to any terrain except tarmac. Does that bother you? | |
| Dec 10, 2014 at 10:28 | comment | added | Obl Tobl | @Slovakov thanks for the comment. I already thought something exactly this way. But i hoped it's more easy or there are some things that can help me with my decision ;-) | |
| Dec 10, 2014 at 10:17 | comment | added | Slovakov | I don't think there's a single right or wrong answer to this question. Because of geometry and tyres used, a road bike will be faster, thus you won't put too much effort in your commute. On the other hand, a cyclocross bike will be more comfortable, and as you mentioned more universal. It won't be as fast though, and note that your speed on unpaved fragments may decrease significantly. | |
