    Default Making the tire carrier removable

    Has anyone made it so they can remove/replace the rear tire carrier? Love the look without it, but also love the originality of it being there.

    My thinking - Cut the carrier off about 1" away from the frame. Make a double ended guide pin with a flange in the middle (flange would be the same dia. as the frame tube) to go inside the tube on the carrier. Weld it to the tire carrier, around the flange, and get it stripped and powdercoated. Use two cute pins or crossbolts to keep it in place when installed then make a slip in license plate holder when it is not??

    Would this be the equivalent of 7 blasphemy??!! Would I be excommunicated?

    You're not adding lightness so surrender your 7 badge on the way out


    In all seriousness however I have a feeling you're over thinking it. Fairly certain you wouldn't care about adding the spare wheel back once you have it gone. Mine has been cut off prior to my ownership and I have no intention of ever trying to mount it back. Granted I also don't have a square setup which makes it even less useful for my application but all things considered I'd say cut if off, have your AAA members ship and not dread it too much.

    Only counter point, where it could be really useful is if you have 13's, square setup and plan on doing very long cross country type trips. That way even if you get towed it would make it hard to source a replacement and the spare could come in quite useful.

    To answer the actual question, I haven't come across anybody who's made it a removable/replicable setup, but I'm sure it's feasible.

    I didn't realize this was fixed in a Caterham. Westfield welds pinch fittings to the rear of the frame for each leg of the tire carrier. Simply loosen the pinch bolt to slide the carrier out completely or to adjust for a specific tire width.

    As to Vlad's point, when I rebuilt my car, I didn't drill the holes in the rear tub for the carrier and don't carry a spare. There are a lot of good tire patch kits out there that include very small and light compressors or that use CO2 cartridges. Granted, there are some situations where this won't be enough, but it's served me well for many years and many tours.

    Yessir! I have one of the small compressors and complete patch kit tucked in the rear side panels of my K1300S. Seat pops off with the key and gives access to the small torx that removes the panels. Have only had to use it once, but it worked perfectly! Even easier to fit in a tool roll in a 7.

    Devils advocate is motorcycles. Vast majority with minor exceptions ride huge distances without having a spare. While there is a better replacement availability nationally the risks are also higher on bikes, but people still do it without a major concern.

    It is (was?) a popular modification in the UK. I think the approach you describe was the most common and popular. A search on Blatchat should provide lots of info.

    Regarding why keep the option to remount, while I haven’t done it (yet), I have clamshells and think it looks “classic” with the spare tire. But having it removable would provide more flexibility, and look better for track day photos.

    Thats fair. Unfortunately I don't have anything more constructive to contribute but if you do go through with it, please share. I'm sure there are others that are considering this as well.

    Exactly this. I have experienced one flat while on the road with bikes for the past 29 years. My k13 that I bought new in 2017 has 21k without any tire issues. Heh, my new to me seven only has 15,xxx miles since 1996!

    bball7754 - yup, agreed!

    I will try the carrier-ectomy in the near future and will post pics when i do.
