i bought an open pro ultegra wheelset. the spokes are 14/15/14 doublebutted. the tension is too low,in my opinion. using my tm-1 tensionmeter, the rear drive side is 20-21, the non drive side is 10 to 15. the front wheel is 11 to 14. on the conversion chart, i'm using the 1.8mm table. it does not show a reading until it is 15 on the park tm-1 meter. 15 is 54 kgf,this is too low. driveside is 88 kgf. i feel like i'm missing something. any help would be appreciated.
