We provide this kit so that you have a wide range of spacers to make sure your BBSHD gets good fitment.
With this combination you can get up to 10mm of wiggle room with your BBSHD install.
According to Karl from electricbike-blog.com the golden rule of BBSHD installation is "Your mounting plate must be totally flat against the bottom bracket Side"
These spacers make that a cinch to happen.
Couldn't finish the product without it. 4 spacers with 2 sizes. It really helps to align the equipment with the bike.
Great kit, it works well. I needed the 1mm spacer to clear the motor from the chain stay and it did well. I recommend it for the fine tuning of the motor position.
Great product .. get you out of trouble and on the road
