Hi, I recently purchased 2 new Shogun Trailbreaker 2 mountain bikes, the other day I noticed that some of the teeth on the front chainwheels appear to be unevenly spaced and not a consistent shape. This appears to be more prominent on the central chainwheel where some of the teeth are shaped like shark fins, others are a normal symmetrical triangle shape and some appear to have a rounded top. The small chainwheel appears to have consistent and evenly spaced teeth, the largest chainwheel has two adjacent teeth which have a rounded top. I was able to locate information on Hyperglide, but the information on Hyperglide appears to relate only to the back gears, I haven't been able to locate any information relating to the front chainwheels. Any assistance would be greatly appreciated. Thanks

Um, was there a question? Yes, your chain rings are supposed to be like that - it improves shifting.

If they are new rings, it will be that some teeth are a little different to (supposedly) work in conjunction with the ramps and pegs in the chain ring, to give cleaner shifting.

Last year I bought some Pace chainrings (damn, they were cheap!!!) to fit a Syncros crankset (which was also damn cheap). The Pace rings have no cunning profiling and shift pins a la HyperGlide, and being used to HyperGlide rings I was a tad apprehensive about wether or not shifting was going to be any good. And it was. Flawless. And it still is.
To the OP, as Bomba and Rimmer said, the funny shaped teeth are normal. Though they threw me when I first got a hyperglide equipped bike.
