    If ever there was immaculate timing on a bicycle failure! The 2year frame / fork warranty on my commuter ran out between 2 and 4 weeks ago. Wondered what was rattling tonight as I tried out my new wheel?

    Ah, pannier is a wee bit loose, I'll just tighten that, except it just keeps spinning. The wee lug thing has detached it's self from the frame, meh.

    Anybody recommend anyone who could weld that back on? Is is worth playing daft laddie and trying to get a new frame on warranty (really should last more than 25 months!).

    Worth taking back to shop and asking them how to fix it and see if warranty is accepted. The lug for the pannier rack has come off?

    I'd be amazed if a whole frame could be replaced for a pannier lug snapping off!
    A P clip will do the replacement for £1.50 any reputable shop that was returned to will fit one on for you.

    If it's a steel frame, you just need to find someone with an oxy-acetylene torch and some brazing rods. Whether 'any old blacksmith' would be sufficent I don't know, but I think Kaputnik knows a good place in Portobello.

    If it's aluminium you may need to do the P-clip thing.

    A 'P clip' eh. Oh well probably best. I had managed to persuade myself that if it couldn't be fixed / replaced under warranty, that I NEEDED one of these:

    or this:

    I'll phone the shop I bought it from and see what they say...

    I may be in trouble, they have the Kaffenback in stock, in the right size and right colour.

    P clips damn it, just buy the P clips. But it's so pretty.

    "I may be in trouble"

    Is that because you are moving towards N+2??

    If N+x = y and you ride the same number of miles, then -

    T/y = bikes wearing out less fast PLUS more chance of a working bike when you need one - every day(?)

    Of course if y is a completely different sort of bike, equation may not compute.

    "Is that because you are moving towards N+2??"

    I'm already on N+2 :) This would just be a frame/fork replacement, I'd just strip the bits off my current commuter, most of them are less than a year old anyway. In fact the only original bits left on my 2 year old commuter are the brake callipers, frame, handlebars and shifters.

    Same trusty brush, just replaced the head 3 times and the pole twice....

    @Baldcyclist, if you talk yourself out of buying a new frame, I'm in Dalmeny and could probably weld it for you, if you like?

    This is assuming, of course, that I'm correct in thinking that you commute in from the 'Ferry. PM me if you'd like me to take a look.

    Oh - and a second assumption that it's a steel frame. My set is a MIG for steel, but if your frame is aluminium / chrome alloy, then you really need a TIG welder, which is a fair bit more specialised (and expensive!).

    you really need a TIG welder

    Tam who (used to, at least) run Sean's Bike Shop cum metalbashing emporium from some units off Bath Street Lane in Portobello could do TIG welding I believe. Or knew a man who could.

    Alternatively you can get through-the-axle (or lots of variations thereof) mounts for pannier racks and mudguards from Velo Orange for bikes which lack eyelets

    Cheers for the offer Skoti. It's an aluminium frame so would need TIG welded. I think I've settled on the fact that I'll just buy a new frame next payday.

    For now I've just hammered the wee round thing into the frame and gravity and friction seem to be working for now. If it falls out again I'll just take the mudguard and pannier off.

    Silly question though, if that happens....
    As the wee lug thing goes through the frame. When it is taken out, it then leaves about a 55mm round hole in the seat stay. I would have thought that it is in a sense load bearing, and that bit of the frame would be weaker, maybe even unsafe as a result? Are the forces exerted on a seat stay enough to snap a seat stay with a 55mm gap in it?

    In answer to the last question - and the whole thread - perhaps time for some high quality epoxy?

    Won't burn the paint off as well as 'fixing' problem(?)

    Balders, don't worry about weakened frame. I know chap from Perth & Kinross, who on a German Audax snapped his frame at the head tube with over a 100km still to ride. He fashioned a fix with a flattened coke can and some tie wraps. The German officials were horrified at the end, apparently. I'll see if I can find a picture!

    EDIT: I'm mistaken, not 100km but 500km! The info and picts can be found here:

    George is now 74 I believe. He and Phil Jurzek (69?) rode the Deeside loop on Sunday on e a Dolan steel tandem, and came in before me!

    I was going to say that I had a lug for the pannier rack for my CdF frame welded on by Eastside Bikes, but then that is a steel frame.

    55mm round hole in the seat stay

    I'm assuming that you've mis-typed the size?!

    A 55mm round hole would leave you with no seat stay!

    My earlier answer assumed it was the eyelet at the dropout that was knacked. Now it seems like it's the one up by the brake bridge?

    "

    Not that location, it's down next to the disc mount points, but it is of that type. The pannier and mudguard screw 'into' the frame. Never measured it, but the diameter of the wee thing when in my hand seemed in the order of 50mm. I need to measure it now... :) It does leave a substantial hole in comparison to the seat stay diameter though.

    It's the one pictured, except on the other side....

    he he, what was I saying about maths in that other thread.... 5 or 6mm. Funny how your brain can deceive you sometimes,and repeatedly! And no EDIT button left to hide the evidence. :)
