An Undignified End?

Filed under: bikes — dgpowell @ 3:33 pm

knackered rim

114.7 miles into friday’s ride, only 0.5 miles from home, sprinting away from the lights racing a mazda mx5 i hit some sort of debris as i flew under a flyover, the wheel stepped out sideways and

pssssssssshhhhhhh, fwop fwop fwop

“oh”, i thought, “a puncture, damn”
i got off and trotted down the road back to my house, span the rear wheel to see if i couldspot and cuts in the tyre and realised that the wheel wouldn’t spin through the brakes, because of the big foldin the rim you can see in the pic (its worse than it looks, in real life)

so there it is, one written off road bike!
if you’re wondering why a knackered rimm = write off bike, it’s because the entre drivechain, both wheels and most of the finishing kit are being held together (quite literally in some cases) by the grime coating the whole thing; everything on the bike is over 6700 miles old and it was bought 2nd hand for £200, so i can confirm that it truely is dead

not sure who i’m going to train all next week without it before i can buy swomething new and shiny
ho hum


  1. Does that mean you didn’t ride today?

  3. can you throw the road tyres on the shopping bike and use that for medium road riding?

  4. Guy: i didn’t ride on Sat, it’s my day off, did an offroad ride today though in the cold and wet

    matt: you smell 😛

  5. ride over here and to loops of the lead mines, it’s great I nearly fell off climbing it today, I got down to 6 rpm! (coming down the road ar 40mph with no rear brake was scary)

  6. What kinda pressure do you run in those road tyres?

    My winter commute I’m currently running at ~120psi, which seems to be enough that I haven’t bottomed out the rim. This is even bouncing over quite large debris. Uncomfortable as hell mind you ….

    Know what you mean about the bike being a write off, my winter hack is the same, on its last legs, but it just won’t die. Writting off the rear wheel would kill it though, as its 126mm spacing, do you ever get to see hubs with that spacing these days.

    What I find odd though is where I do spend money on the hack, just put on £30 of new tyres (Michelin Krylion Carbon), cos I recon they’ll only last 6k miles, and even if the bike dies and can just salvage the tyres.

  7. i ran around 90psi in the tyres in winter to get a bit more grip (frankly any grip would be nice round here!)

    the only things i replaced on the “shed-bike” were the saddle (for something i new i’d get on with for many hours), the tyres (for some better, lighter, puncture resistant ones) and the brake calipers (for something that actually worked!)

    as you say, the saddle and tyres will be getting reused on the new replacement planet x

  8. Grip! Ah yes, tell me about grip.

    Last part of my commute is on a path by a river. The river flods at times, so the bath has a good 2″ of soft mud covering it at this time of year. This and 700cx23 tyres at 120psi, yes it does get a tad squirrly. Try cycling it at 20mph, that really is scary. [Used to tell myself that the greater the speed, the more gyroscope effect in the wheels, and the more stable I’d be!][silly theory]

    So whats the replacement, a Kaffenback?

    Here I am in at the office, with 5 days to go to my first TT, thinking I should do something like 100 miles of commuting this week. Then looking at the forcast, and thinking …. boy I’m gona get wet. Thing is dare I let up on the commuting? Have that TT to prepare for afterall ….

  9. the replacement; a planet x superlight, not sure what groupset or wheels yet, but probably something over-the-top

    maybe keep the commuting but drop the intensity each day in the run up to the event to make sure you’ve got lots of energy on race day?

  10. Poo!

    Who’d have belivied it, but a day after posting here would you believe I’d done the same thing.

    No, not bottomed out a wheel and dented a rim; but probably wrecked a bike through a silly wheel failure.

    So was commuting in today. In one place there is a small climb (1 in 20 or so) to and over pass over the dual carrage way. I was feeling good this day, had just been motoring along at 25mph in a 68″ gear and all. So the 1 in 20 hill you can motor up at something like 20 mph, I was feeling good so really went for it. Put huge power down, and twang! Back wheel went all kinda squiffy.

    Snapped a spoke in the rear wheel. kind sounded like the panier had some how got caught up. But no damage to the pannier. Think it may have just been putting the power down and fatigue in the spoke. Hey, these spokes are only like 20 years old. What right do they have to die.

    Looks like the hubs OK (good as can you find 126mm spaced hubs these days). Quick glance at the rim, and although buckled, doesn’t look beyond repair. So real question is can I replace the spoke.

    Here it starts getting hard. Need to remove the sprokets here to get to put in a new spoke. sprokets have been wond tighter and tighter with 20 years of cycling. And oh yes, there is alot of mud and grime in there. Don’t know if it possible to get those sprokets off.

    Then comes the question, what if I can get the sprokets off? They are worn as anything (only the 14 and 20 cog work any more).

    So should I just have a single cog put back on. Or even go fixie.

    But in all probability any bike shop will just laugh at me, and say the wheel is wasted.

    But as this is a 23 year old bike, its really not worth putting a new wheel on.

    Pooo. Pooo. Pooo.

    On another note, Brant is giving you a superlight eh? Boy you’re gona get a surprise. superlight is a real road race bike. *very* light (mine built upto 7.4kg = 16.5lbs). Stiff bottom bracket. A real road race machine. It just wills you to go faster and faster.

    If you want to fit mudguards, you’ll have a stuggle. Nowhere to attach the guards to, and there isn’t really the space. So its maybe not ideal as a commuting bike.

    Poo. Poo. poo. Just realised I can’t cycle in the rest of this week, as I’ll probably not easilly be able to get my bike fixed. poo.

    Don’t really want to commute on my superlight (cos if its wet, grit goes everwhere, at least it did on a 50 mile ride on the superlight on sunday – silly idea).

    Pooo. pooo. pooo.

  11. did you get home ok with it then?

    oh, and i think you should go fixie 😉

    i’ll probably just use my old race blades as mudguards on the superlight, they’re not as good as full guards (esp for people behind!) but they’re OK…plus it’s nearly spring, so it should be dry shouldn’t it?!!

  12. I limped home trying not to put any forces on the rear wheel. It was very ratty with any sideways force (say when cornering) but rolled along OK.

    So usually these days I cycle home like a manic in 1:03 or so. Last nighed don’t think my pulse ever went above 140bpm, probably down at 120bpm for much of the ride. Still got home in 1:23. [Damp though – it was raining …]

    Yes, the fixie is looking the most viable direction. My small cog is 42mm chain line, good for a 120mm spaced fixie wheel. A 120mm wheel can easily be respaced to 126mm.

    Just waiting to see what Brant can come up with really.

    So superlights, and rain. Just as you went out last sunday and almost died; I went out on my superlight and almost drowned. So when I got home, the superlight was actually mudier than my scandal! Stripped off clothes and put them in the washing machine. It was only after they had been through the washing machine, and come out again, I reallsed that they were *still* plastered in mud and grit! Clean mud and grit though!
