This brake adapter can achieve +20 or 23 and +40 or 43mm rotor size
These adapters are special, and only the freaks of you will notice that. The PMPM+20/23mm adapter has 4 bolts, but looks tiny just like one with 2 bolts. The difference is: the normal 2 bolt adapter needs to have spherical heads and washers, which are able to compensate the small angle difference between fork and caliper. With the Extension Brakeadapter you have a solid 4 bolt mounting of your caliper, with a clean looking appearance.
And the second point is, you can mount it as a +20/40 or +23/43mm. Without extra parts.
Features of the Intend Blackline Extension Brakeadapter:
- 26g (+20/23mm) and 32g (+40/43mm)
- +20/23mm version suitable for +20mm AND +23mm
- +40/43mm version suitable for +40mm AND +43mm
- All necessary bolts and washers included
