Ottrott max tire size
One for owners of the Ottrott please. In your experience of this frameset (using a Serotta F series road fork) what is the maximum tire size? It would be helpful to me if you could name the rim/ tire combination that works on your Ottrott.
Also, what is the maximum brake reach on your machine please? Much obliged, Sparts. |

Using HED wheels with the C2 rims and tires that measure an actual 28MM, fit. It's been my experience using this combo that the brakes and their clearance to the tires, or lack thereof, is the determining factor moreso than frame and fork.

Thanks Dave. Not sure about the physical size; http://www.fm-boyaux.fr/rubrique.php...5raht9sbu3usu2 Reassuringly they also come in 25mm which should give ample clearance, but fat 27mm would be best. I'll do some leg work and find out. Fancy looking; http://www.fm-boyaux.fr/client/cache...g_edit_105.jpg Last edited by spartacus; 11-09-2010 at 10:02 AM. |

The FMB PR tires look tall. If that's true then there will be problems with the 27s not having enough room to clear the front fork. Maybe 25s then. But yeow, $250 for a pair of tires!?

Are the 28mm tires you referred to earlier the Vittoria Corsa EVO CX? |

I also run 25MM Continental GP 4000 on the same wheels and they measure an actual 27.5MM. |

Many thanks Dave.
Sounds like the issue is the fork clearance, and the variability of nominal tire sizings. Did the Vittoria tires have a good puncture record for you? |

As for flatting, I rarely get any punctures with any tire so I'm not the best one to be judging them. I will say that I absolutely hate flats and do quite a bit to prevent them, even going going as far as filling little cuts in the tires when I get home from a ride and performing routine maintenance. All that said, I really like the Vittorias and deem them the very best clincher, all things considered, of any clincher tire in the marketplace. |

Well, I got a quick and short reply from Francois Marie Boyaux (Mr. FMB himself) about the actual physical size of his Paris Roubaix tires;
"The size of Paris Roubaix 25 is 25 mm. The size of Paris Roubaix 27 is 27 mm." Perhaps something was lost in translation. |
