Ive used then several times and never had a problem. They were a very nice looking piston. B is the size.

Reason I asked is cuz a guy at local mx shop said don't use wossner aa they snap top of piston . He said to use vertex piston and put me off it ? Prob just trying to make me get my bike in his shop for a expensive rebuild at £300 all in top rebuild ... Someone said when useing forged piston like wossner have to let it heat up warm up more than other postons .. Why is this then ? Thanks
