    Replacing rear bolt on axle / cups on old road bike

    Basically my old `80's KHS uses a bolt-thru rear axle which has 16mm head sized nuts attaching it to the frame.

    I took the rear hub apart to service the bearings and one of the cones is totally fubar'd, it looks like the cage retaining the bearing on the freewheel side of the hub exploded inside there and the cone tip is 1/2 missing from wearing on the aftermath.

    Ideally I'd like to throw a quick release setup on this wheel, and I have a spare 700c 7spd rear wheel that I'd like to convert to, but I have nice new continental ultra sport tires on the bike that I got right before finding the new wheelset that I want to wear out before making that swap.

    So, tl:dr, can I upgrade the rear wheel to quick release for cheap, or what do I need to measure to ensure I get a replacement axle set that fits?

    I found these on ebay and was curious if it would work?

    does the size of the cones matter at all? I'm pretty sure my hub is a suntour.

    conversing from a solid axle to a QR is easy . what you show on ebay is still a solid axle not a QR axle . just go to your LBS and pick one up . yes cones size does matter . take the good one the left side to match. you don't need the cage retainer ,just replace the bearings ,18 of them ,(9 0n each side ).

    so then it wouldn't be out of the question to pull the quick release axle and skewer from my spare wheelset and swap onto these wheels?

    So I tried my spare wheel, and while it fits the tire that's on it (700x40, it came off a hybrid bike) is too wide for my frame, no matter how tight I made the QR as soon as I put some torque to the pedals in a high gear the tire would rub the non-drive chainstay. Plus that wheel is a 7spd and fairly wider than my 5spd setup frame. Eventually I will spread my frame to make this easier to get on/off, but as it is since I'd need to buy a skinnier tire to use the wheel right now I'd rather just repair my current 27" wheel that has a tire with only ~200 miles on it.


    Would this 126mm QR axle be what I need to replace my bolt-on style and get my bike back on the road?

    All I'd need in addition is a skewer and 9 bearings + grease on each side?
