    Hi,
    thought someone may have known since the fork is popular. 17mm axle and 133mm space. I will just have to measure a few vintage wheels i have around and may have to replace bearings and make spacers and or machine inboard legs for clearance. which is what i did for my g/star with CERIANI fork and 4ls brake set up so there was not stiction. thanks,joe

    The axle is different diameters on each side (1" and 1/2"). I made my own axle when I fitted the Ceriani's to the Sporty. Many wheels will work with a custom axle. Keep in mind the Ceriani's are a very narrow fork.

    metric since it is an italian unit…15 mm RT and 20 mm Lt.. first is to see what readily available front wheel has 17 mm inner bearings. i had a cb 750 sitting around but since the cb750 has 15/42 bearing and there is not a 17/42 bearing which i would need to make it work. make a 1mm per side spacer which is not a good idea or make a new axle ..
    If anyone knows what mfg uses a front axle dimension of 17mm it would be a good start. i emailed a few e bay auctions for info.

    What wheel and tire are you trying to squeeze in?

    "or machine inboard legs for clearance." Huh? Been watching the Jaffe clown on Biker Build off?

    the original Ceriani 35mm forks don't have a "bolt up" option - anything you are going to use you are going to kitbash from various sources. I know for a while the factory XR750 HD road racers used Morris Wheels with SOHC cb750 brake calipers but the caliper mount was custom and real racing Morris wheels and rotors for an XR are no longer available and very expensive (and not the same as common Ironhead/Evo morris mags).

    Ducati used 38mm Ceriani's on some of the bevels. These use F08 Brembo calipers and are as close to a bolt on disc brake setup you are going to get with ceriani forks. I think the Guzzi lemans 1 used 35mm ceriani forks with the F08 caliper as well but they have specific caliper brackets on the lower legs the standard RR forks do not. I have heard that it was once popular to put 38mm ducati cerianis on the guzzis and seen a few with this conversion.

    have you contacted Paioli? they own the Ceriani name now and make suspension components. There is also a company that is repoping the old 35mm road race forks and they may have a disc brake setup.

    Seems to me that you won't find any axle ready made for whatever wheel you decide upon. A custom axle will need to be made so you can make it whatever diameter is necessary to fit the wheel bearings.

    If the Ceriani's are the same as ones I have the axle will have, depending on bearing size, 3 different diameters. None of the axles on that list will likely fit without modification. The big end of the axle is held by a pinch bolt and the other end has a nut on the end and pinch bolt. I have dual discs on mine and let me tell you everything is tight as far as clearances go. I would consider disc spacing and caliper mounting long before I hit making a custom axle on the list. Doesn't take 1/2 an hour on a lathe to turn an axle.
