killing parts!

Postby foxyrider » 13 Jan 2021, 6:25pm

So last week i ordered a new back wheel, the one in the bike has served well but the rim is quite worn and the bearings are shot after a particularly hard year of riding and many years of general abuse. Anyhow, delivery is expected next week - no problem says i, pretty sure the bearings will last me that long and the brake track isn't that bad, and the wheel is still true. That is until today, horrible damp, windy weather, a strangely large amount of spilt deisel on the damp roads, i didn't give the squirmy braking too much thought, the tyre was inflated, the wheel looked pretty straight still. When i got back tho, it was immediately obvious what the issue was!

Yep, complete failure of a nipple hole, i've missed the warning signs because of all the crud on the roads around here coating everything in a liberal layer of field, the last de-crud was a week ago.

So my pre emptive wheel purchase has now become a desperate replacement need!

Perhaps i should offer my services to the bike trade - i seem to be able to kill just about any component - at xmas it was the BB and the headset on the same bike is, i know, in dire need of attention as we speak! :lol:

ps - my bikes do get cleaned and serviced, i don't use cheap parts either.
Convention? what's that then?

Wow - can I ask which rim it is, make/model?

I have seen many rims fail in that kind of way. If similar it'll be;

- a driveside rear spoke
- in a wheel with full dishing eg 8s/130mm
- a tight build
- statistically it is most likely to be within a few holes of the rim joint,
- in a single-eyelet (or no-eyelet) rim,
- with PG spokes not DB ones
- the rim isn't corrosion proofed around the nipples
- the wheel is used on a bike that sees freshly gritted winter roads and relatively infrequent washing
- the bike has either no mudguards or mudguards which lack a long front mudflap

IME it is unusual not to score at least 6/9 when a failure like that is seen.

cheers

I have seen better wheels in a museum !

when as this wheel last cleaned ? ..................looks like it was knackered before it rusted out the nipple - looking at the braking surface - or lack of.

I can't comprehend how you let your wheel become so ''tired''. bearing in mind you say that you clean and service it

last cleaned 3 rides ago - most of the crud was from the previous ride in S Gloucs 2days before. Hasn't rusted out at all, its Al, and under the crud there is a worn but still serviceable braking surface.

If memory serves its an 'Omega V', the wheel is a Raleigh Trubuild of about a ten year vintage.

6/9 is about right.
Its not a particularly tight build, its never needed any attention from new.
Not a lot of gritting on the roads around here until the last week and crud is usually washed off after each ride - the hose froze at the weekend and the nozzle is now kernackered which is why there is so much on the wheel - its mostly from the previous ride.
Full mudguards since September - there is a longish front mudflap but indeed muck does get past that.

The wheel certainly doesn't owe me, i've got a duplicate build (the hub's more a project than economic repair!) on order, if i get the same service life i'll be well happy.
