Re: Quick Torque Cam & Speed Cobra
From what I know, Tama's Super Spring uses a more hardened, brittle alloy. You can tell it is more responsive on the end of down-stroke of the pedal. I had no issues for 5 months until a week after installed the QTCs.
Like I said, the QTCs do make a difference and I am holding on to them for their value. That being said, they just aren't for the Speed Cobras. I would experiment using a regular IC spring with them installed, but I'm getting good response with the stock Speed Cobra components with the Cobra Coil, Speedo Ring, and Super Spring.
