## Description

BUCKLOS PM/is Front Rear 180/203mm Disc Brake Caliper Mount Adapter Gear Parts Accessories, CNC Machined Aluminum Alloy Rotor Adapter with Bolts

Review: This adapter worked perfectly on my Ibis Ripmo v1. It bolted right on and positioned the caliper for my new 203 mm rotor which was larger than the 180 mm rotor that my bike came with. To be clear I ordered the "PM Front/Rear 203mm" version. There is no documentation so it took a minute to figure out the correct orientation on the bike. I am including a photo of my mount in case it helps others. Overall I found the Bucklos adapted to be a great value, especially compared to the higher cost part from Shimano. I learned a couple of things through the process of identifying the correct part. Originally I ordered the wrong Shimano adapter. This was primarily due to Shimano's poor documentation on their website but also due to a different seller listing a partial part number. Ibis support was great and they confirmed that the part number I needed was SM-MA-F203P/P. The important thing to know is the original rotor size that your frame is designed to use directly mounted without an adapter (sometimes referred to as "native" size). While my bike originally came with a 180 mm rotor, it also had an adapter. Turns out the "native" direct mount size was 160 mm. So this Bucklos adapter was exactly what I needed to run 203 mm on a 160 mm frame.
Review: i have ordered a few of these for my bikes and clients. the fit and finish is great. price was also great. love how easy it is to install. got it installation down to under 2 minutes. will be ordering more in the future. shipping was quick and packaged very well. no damage and quality is wonderful. the work great on the bike and look great.
