Nearly beaten by a flippin' BIKE at the weekend!! Needed a new wheel - the cones and hub were knackered, and it didn't run very true anymore, been straightened out too many times. Also a new mudguard (fell off trying to show off to a 6 year old....

) No bother thinks I

Wheel out, tyre off (which also needed replacing), tube looks OK. Fought the block off (how tight had that got??). Off to the local bike shop but no good. So off to one a bit further away turned up a new wheel, tyre and muguards. Easy! Er, no. offer up the wheel, nuts on the axle to wide to go in the frame, so swap nuts and spacers around from the the old wheel till it fits. Centre the axle after a fight, then adjust up the cones (eventually - but only after I got one side in the vice to counter hold it). Back in the frame, and find that the axle is too long, and the skewer won't tighten up. Swap the axle for the old one. Fight with the cones again. Find that the block is scraping on the back of the cone - which turns out just to be a washer pushed on when I get it free. Adjust the cones again. Getting there now.... fit the tyre and pump it up - pffft tube bursts at the valve! Off to Halfords to get a new tube.... Get the wheel in, new tyre is just too big however, I look at it. Back to the bike shop (1/2 hour drive) to change it for a smaller one. Get that fitted and wheel back in the frame. Start on the mudguard OMG!! the small bolts that hold it in just do not want to stay put, and you need to get all 4 in at the same time. Get there in the end. Now need to adjust the brakes - which needs about 4 hands. Then gears to suit the block which has moved a bit. Took me about 6 hours all in - twice as long as it took to replace the cam belt on a 1.6 HDi!!! Goes much better now as I also rebuilt the bottom bracket which had seized solid when I went to get it out
And now I have to go and de-sump the C4 Picasso again. Ah joy....!!!
