OK, to the best of my memory on the rcm pinions.

The earliest ones were actual clutchbells turned down and pressed onto machined hubs.

Next he got RRP to make them, to a certain spec (can't remember if it was rrp spec, but I think it was) so eventually rrp started reselling them as their own.

Now he has another firm make them, to his spec. The material he uses is better than the rrp (next best from rcm) and the heat treatment is also better. And the price is right in line, and we all know Mike's service is top notch.

From my experience I have noticed much more wear on the rrp pinions that I run compared to the rcm. Got the rrp pinions at a lhs closeout for a few bucks each (would not have paid full price, that is for sure). I will gladly pay what Mike asks for his pinions, just a better product than what elese is available.

Given your use of a steel spur FB, the pinion will wear more than someone using a plastic spur. Plus the spur has about 2.1 times the number of teeth, so the pinion will see 2.1 times the number of wear per tooth compared to the spur. So it has to be considerably harder than the spur if both are to wear at the same rate.

My best advise to you would be to replace the spur and get a rcm pinion. Using an old spur with a new pinion is not optimum, as the wear on the spur (even though it is less) matches with the wear on the pinion. Yeah it costs 25 bucks for the spur and another 15 or so for the pinion, but it is money well spent, and you can always keep the old spur as a spare. Or sell it to the idiots over at savage central... They will not be able to hear the noise over the sound of their 28c 3200 mah lipos exploding under the strain...
