In addition to the burrs, there may be non-obvious wear in the "valley" of the tooth pattern - you essentially elongate the dip. I usually match up the new under the old to determine how much change to the shape has occurred. The burrs are probably the cause of chainsuck, but the more rounded out the pattern becomes, the quicker I seem to burn through chains.
Also, steel chainrings are a good thing - especially in the high stress applications (say if someone were to ride their Quickbeam in fixed mode 95% of the time) or on smaller rings. - Jim / cyclofiend.com -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
