[RBW] Re: Chainrings...when to replace?

[Ron Mc]

I have over 4000 mi on my XD, compact double, 99+% of those mi on the 
single 42T ring, and it runs great.  I bought the bare arms, the 42T from 
Riv, and the 25T granny is a Willow..  On other bikes, my experience with 
TA rings has been great, and will replace this with TA when it's time, but 
it's not even close to time...
Have you looked at chainline?  Does it make noise?  What do you do for 
lube?

In the photo there is visible wear on the middle & outer but nowhere near 
the point of replacement.  Have you checked that the new chain is correct? 
 I actually used a 9 speed chain on an 8 speed drivetrain without noticing 
but I may have been lucky.  Weird stuff can happen that way.  If you're 
having shift problems after changing chains, it could be the chain.

I am guessing my Sam and Bleriot have similar mileages but the Sam's xd2 rings 
look better than the xd600 rings on the Bleriot.

Ill have to go back and check some of my old ride tecords and mileages. My mind

[RBW] Re: Chainrings...when to replace?

[ascpgh]

Those TA rings are the finest. My Zephyr crankset introduced me to them and 
I am now ruined to others. Fit, finish and durability. I wasn't a chainring 
elitist until trying these.

A choice not wasted if you dare.

Interesting, when you call the ring "inner" ring instead of "middle" ring, 
you get the 33t included, but no 39t:

Maybe try the Willow Chainrings (available for 110, 74 BCD)? David Banzer 
on this group has 'em for sale:
http://treetop.bigcartel.com/category/willow-chainrings-c

Do you need a new granny?

Agreed that 3,000 miles on chain rings sounds low. I've got at least double 
that on Sugino XD2 w/o signs of needing replacement. (Riding 4 seasons in 
Boston area.)

Good luck

Re: [RBW] Re: Chainrings...when to replace?

I've got almost 13K miles on a 46 t Pro 5 Vis chainring with no wear
visible to the naked eye, this under my mashing pedaling style (it's a 76"
fixed gear). 3K miles means that something is wrong. I do change the chain
every 2K miles or so.

[dougP]

"But I think I only have 3k miles on them."

Are you sure?  Miles can add up quickly.  That's incredibly low.  I get 
around 20,000 miles on a middle & outer, & use whatever's on sale for 
rings.  The granny is steel & is the original one Riv put on in '03 when I 
bought the bike.  I'm in a dry climate & don't bother replacing rings until 
seriously worn (but not troublesome), so my mileage may be at the upper end 
of common.  Perhaps someone from a more aggressive climate could comment 
but IMHO rings ought to last at least 10,000 miles.

3000 on some chainrings seems really low.   I'm taking it that you are a

How about the chain, how many times have you changed it so far?

[RBW] Re: Chainrings...when to replace?

[dougP]

Yep, you're due.  With a new chain acting up, it's wear on the rings.  If 
you change rings today, you will notice an immediate reduction in the 
amount of noise the drivetrain makes.  Rings wear so gradually that things 
get pretty rattly, even with a new chain.
