ADD THE REAR ADAPTER FOR 15% OFF WITH THE CODE: 180BUNDLE

On peak-torque.com since 2022 - I created these adapters because at the time, there was no solution to road/gravel 180mm brakes. The original. Here it is. 

The PT BBC 180mm adapter allows you to run a front 180mm disc rotor on your 160/140mm flat mount fork (as per the Shimano standard). Road, gravel, and bike-packing. 

The aim here is to increase the thermal headroom of your disc, pads, and caliper pistons if you are a heavier rider trying to dissipate large energies in hilly and prolonged fast braking situations. This will increase the lifespan of the pads and discs. A secondary although lesser benefit is an increase in peak braking force. However, if you brake with the same deceleration as a 160mm disc then the braking force will be the same! 

Made from 7075-T6 Aluminium, with all hardware included.

Note: Your existing fork caliper mounts must closely follow the Shimano specification of the 70mm hole position tolerance. As there is little wiggle room for the counterbored mounting fasteners, please check your fork is well made, faced and accurate before ordering. Please check the disc clearance and fork mounting tab clearance illustrations below. 

Note 2: The peak braking force will increase by at least 12.5% over a 160mm disc. The increase in braking force is given by the larger disc diameter and reduction in temperatures at the pad. The small increase in braking force should be well within the bicycle's design safety factor but the use of this adaptor is at the user's own risk. It may not be validated by the user's fork, frame, or wheel manufacturer. Any damage, injury or death incurred arising from such use will not result in any liability incurred by Peak Torque. 

Note 3: You must use the fasteners provided so as to not interfere with the fork, and it is recommended to use a low strength thread locker (e.g. Loctite 222) on all fasteners.

Quality meets style
Color: White, Size: Large, Color: White, Size: Large
This is an Oxford button-down dress shirt that is a great example of quality craftsmanship paired with classic style. The 50% polyester and 50% cotton fabric has a nice substantial weight to it that feels durable without being too heavy, making it perfect for a polished summer look. The detailed design around the collar adds a subtle touch of casual sophistication, and the chest pocket keeps it practical and versatile. The construction is impressive, with securely attached buttons that reinforce the overall sense of durability. I also appreciated the inclusion of two extra button which is a thoughtful and useful addition. The size large did run a bit snug so I’ll be ordering the next size up. This is a well-made shirt, of a quality-feel material. This brand continues to deliver on both quality and style, and the price feels more than fair for what you’re getting. Overall, a very nice summer dress shirt that I’d gladly recommend.
