Alright, so now that we have determined that it can be dangerous and why...
Any input regarding a combination of spacers using a Mavic 2mm and Shimano 7 speed cassette in order to achieve 4.5mm?
Can I simply sandwich two spacers together without worrying..?
I am living in Qingdao, China so ordering/obtaining the 4.5mm spacer is pretty much out of the question.
Thanks again in advance for any input involving the combination of spacers.
