With these 2 piece adaptors. I have not found any that once tightened down that each piece meets each other perfectly flat and still tight on the hub. Ones I have seen will tighten down good and hold and do the job but the adaptor pieces never meet perfectly flush. Has this been everyone else's experience? I talking about the something like the BBR tuning sprocket where you have the 2pieces that fit over the hub and then 3 bolts hold the sprocket to these.Thank you
