Dangerous bike

Well, had a bit of a moment on Tuesday on my commute .. my bikes
getting up to the change the cogs etc moment ... basically under full
power away from the lights the chain comes off at the front chainring.
You tend to go down very fast when you have no chain .... One bruised
gonad later I decided it is time to replace everything.

So, I've replaced the chain and cassette and am thinking of changing
the triple to a double at the front. It's Sora stuff and am wondering
if the gear switcher thing will cope. Any ideas?

/snip

Sounds a little drastic to me...

That snip was a little too well placed!

Can we please stop talking about snips and gonads? :-(

Was the cassette damaged by the slip up (or the cause?) I would have
thought it better to replace the front chainrings if they were the
problem... It sounds like the derailleur might need a look at though
if it's allowing the chain to come off the chainrings completely.

It could've been worse - the chain could've come off the back cogs and
(a) jammed between the cogs and frame or (b) jammed between the cogs
and spokes. (b) happened to me at the weekend while slowing from
35mph for a right turn - slowed me down all right!

My bike is hitting 2000 miles .. (plus) ..

I think that is a big prob for my middle ring ....

Sounds like we're heading into a sensitive area ;-)

If you need to replace the chainrings because of wear, you definitely need
to replace the cassette. Not doing so will end up getting /very/
expensive.

It sounds like the derailleur might need a look at though
if it's allowing the chain to come off the chainrings completely.

Why?

yup the cassettes are normally softer i certinaly worn out the cassette
on my old bike, now has a new one, while the chainrings are still fine.

I seem to eat them the other way round, well on my MTB anyway, my
commuter has never had anything replaced yet!
