Sorry, no. On my 68mm road bike, there is still not enough crank poking out with one spacer on the drive side so zero spacers it is, as recommended by this top of the google search list vide which (I remember the guys face) is the one I watched when I set up my previous BB. The play I was talking about is just because the bearings are now shot. Please mention in your article that your advice is only for MTB bikes, and that road bikes require no spacers.
Apparently road bike BBs and MTB bbs are different. If I am using a road bike bb on my road bike then I should need no spacers, according to a post on the Internet here but the aliexpress advert says it is a MTB BB, it comes with three spacers, and is for 68 to 73 bottom brackets. All the same, there just is not enough axcel sticking out now to securely mount my non-drive size crank, not to mention that my front deraileur is of course rubbing. I have to take spacers out to be able ride my bike without damaging the non drive side crank. I see that on Youtube I am told that "if it is a road frame", as my frame is "no spacers are needed." I think I am going to go with that. It seems to me, however, again, that to eliminate play, so that when I tighten up the plastic (on my 105) crank retaining nut, one spacer on the drive side would be good. I see that the above article is on a site called "off.road" so I guess it is for mountain bikes but it does not say so in the article. I think it would be a good idea to mention that the above stands for Mountain Bikes and that Road bikes need no spacers.
Though, as I say, my gut tells me that one would be nice.
My BB is 68mm. I did not read anything about set up last time and used zero spacers! I did think that there was a little play! But now with three spacers it is like there is not much axle poking out of the left non-drive bb. Do I really need to use all three?
