    Default Converting from traditional to cycle wings

    I have a cycle wing kit from Caterham and just read the installation instructions. They refer to the "prescribed position of the mounting holes" in the wing, but there is no position marked on the wings. These are the wings for 13-14" wheels. If anyone here can let me know where the prescribed positions are I'll appreciate it.

    Thanks/Anker

    Without knowing what you got in your conversion kit, I should probably withhold comment, but that has never stopped me before. It seems to me that the method the factory recommends for wing installation on new kits might work best here too...glue them on. Using Sikkaflex 721 place a bead along the top of the stay where it touches the fiberglass wing then use tape to the wheel to hold it firmly overnight until it sets. Then put a nice cove bead of the stuff on both sides of both stays. Job done. As for location, the front edge of the wing should be 80mm or 3 1/8 inches ahead of the top stay. This makes a clean and drilling free install that is really stout.

    Good luck with the new look!

    My CSR wings are bonded on the same way I B Sevener describes.

    A variation on I B Sevener's very good suggestion above, that is common in the UK, is to use bigheads and bond the wing to it. Refer post 17 and 19 in the link below

    I B Sevener is too modest but the reason bonding is a better idea than screwing wings on is that:
    - they are easy to cut off to remove or reposition if you goof up first time
    - no stress or fracture marks in the fiberglass wing around the bolt heads.

    So I got the right front cycle wing installed. It looks great. It does, however touch the body side then the wheel is cranked way to the right. I tried the same on the left side and the mounting bracket does the same thing.

    Doesn't bother me, but I do wonder whether there is a stop that could be installed to prevent this from happening.

    Yep, Caterham can provide stops (aluminum bushings held in place by set screws) for use on the steering racks of cars with cycle fenders.

    You could also easily source an appropriately sized shaft collar such as one of these: https://www.grainger.com/category/po...ch-_-IDPPLACAT

    This helps explain why the turning radius of a cycle wing Cat is so much larger than one with clams.

    Thanks Nick,

    Simple. I didn't realize that it was that simple. Will take a look later today to see where they go and take measurements so I can order them.
