Alloy wheels; how long do they last?

[Andrew_Culture]

My alloys are quite possibly older than I am; I got them when a friend was chucking them out and they have flat bits on them were someone (not me!) has thumped them up and down kerbs and (the previous owner) used them to hack around the local reservoir MTB track. A a guess I've had about 1500 miles out of them in the last four months since getting them. They are now very difficult to keep clean and the braking surface has more groves than a 78 and they're deeper than the tracks on a fisher price plastic 7".

I break a spoke (or two) every few weeks because I guess the spokes are getting metal fatigue.

Yes, I'm planning replacements, Rigida Flight rims apparently (this is a single speed).

What was the original question? I kinda went off on one then.

The rim's no use now ! How are you ?

Keeping very busy mate.

It'd be good to see you somewhere sometime!

You're making a big deal of that!









Deal - timber - geddit?

Longers!!

Indeed.
Which I am and went through a rear Shimano RS20 rim in just over a year.

Out of interest, why do you think the rear went first? I would expect more wear (a lot more) at the front.

Big skidders

Jousting innit? Avvvvvanti!
longers how the devil ARE you? Great to see you here again! We must get @potsy to organise a ride in that Manchester somewheres...

For the OP: You are correct about the wear groove. Once it disappears the manufacturer would like you to replace the rim. HoweverI think the limits are a bit conservative, and you can a bit further than they indicate. I don't usually replace a rim until the rim starts to bulge outwards and foul the brake blocks. There are lots of stories of wheels exploding due to rim wear but I haven't had that yet, just the bending of what's left of the rim.

Have no idea...

even less wear then, as the skidding wheel ain't rubbing against the blocks

spray from the front tyre goes over the back wheel, and a dirty wheel wears faster than a clean one.

I'll buy that

More of your weight is on the rear; I've had a few rear fail but never a front touchwood.

I won't!

 

[VamP]

I won't!

I have managed to wear out blocks in a single muddy CX race, so I do find that explanation fairly plausible...

Weight transfer under braking negates that I think...
