The SHIMANO SM-MA90 Disc Brake Adapter (for Post Front) was exactly what I needed to mount the SHIMANO M375 Post Mount Brake Caliper for my front forks brake. The adapter is a well made, quality part which came w/the 2 bolts & washers needed to mount it & the caliper to the bike forks. The bolts came w/thread locker preapplied. The adapter is also labeled so you know which way to mount it. This adapter was perfect for the caliper’s post mount holes, allowing for the 180mm SHIMANO XT SM- RT86 rotor to be installed.
If you need an adapter to mount a caliper & allow for a 180mm rotor on the front wheel of your bike, the SHIMANO SM-MA90 Disc Brake Adapter (for Post Front) should fit the bill.
Thank you for taking the time to read this review, I hope you found it helpful.
