I actually have a set of 1" spacers on order from the states, but found a cheap set of 2" locally while I was waiting for them to arrive. To be 100% honest, the look of 2" plus the fender flares make any prematurely required maintenance worth the cost. I'm hoping the 1" look as good. As for the additional stress it will put on my bearings, I'll just replace them if it becomes an issue, but I'm not overly worried. Besides the aesthetics, the main reason I wanted some additional width is for stability on higher speed corners, which these deliver. I live in the middle of Canada, so the overwhelming majority of riding is done on fast and flat trails. I don't think we have a hill for 200km in either direction from where I live lol (sad laugh)
If that’s how you like it, leave them on. You’ll be fine with 2”. I’ve got 2200km on koyo bearings that are underwater on every single ride and my 1.5” spacers have been on there the entire time. My right rear is starting to play and that’s more likely from the rock that twisted my wheel and then riding it like that for another 400km. Everything fun adds required maintenance, let ‘er buck.
