While riding this past week I had a few occurrences of what seemed like a bit of chain suck which quickly corrected itself. I’ve also been having a problem with the chain dropping into the smallest chainring up front, telling me that it’s time to look at (and readjust) my drivetrain. Looking over the rings this evening I found this large burr on the middle ring, along with a whole bunch of wear†, which means that it’s time to replace the middle chainring. I also got to looking at the cassette, and it’s likely due for replacement too, with small burrs forming on the more commonly used cogs. The chain is fine, with Park Tool’s CC-3 indicating less than .75% stretch, and thus safe to continue using.
When I built up the Salsa El Mariachi I used a Race Face Deus crankset purchased on a deal from Wickwerks which got me the crankset and a triple set of Wickwerks rings for just under $200. With the crankset now fitted with a Surly ring I have the Wickwerks rings left over and ready to go on the Titus. While the smallest and largest rings aren’t worn enough to replace I think I’ll replace them anyway so that I’ve got a matching Wickwerks set along with it’s high performance shifting.
I’ll probably do this all sometime later in the week, as tonight’s going to involve going to bed early. In the mean time I’ve got two other excellent bikes to ride.
