When the trail drops into a steep descent, you want confidence at the lever and peace of mind. Cannondale KP421/180 flat mount brake adapter 180mm helps match your frame or fork to a larger rotor, without unnecessary compromises.
This adapter converts a Flat Mount interface to a Post Mount caliper mount, making it easier to pair the right components on your bike.
It’s designed for a brake rotor with a diameter of 180 mm, which you’ll appreciate on longer descents and under heavier braking loads.
It helps maintain clean routing and correct caliper positioning, so the pads engage evenly and without unwanted rubbing.
It’s ideal for riders upgrading their brake setup on gravel, road, or mountain bikes who want stable, predictable braking performance.
Mount type on the frame or fork: Flat Mount.
Caliper mount: Post Mount.
Designed for a 180 mm brake rotor.
Compatibility follows disc brake standards for the listed mount types.
Cannondale KP421/180 is a practical adapter for situations where the frame or fork uses Flat Mount, but the caliper requires Post Mount. With support for a 180 mm rotor, you’ll gain more confidence under braking, especially on descents. It’s a small part that can make a big difference in how your disc brakes feel and perform.

Hello, I own a 2019 Cannondale si6. I want to get better cooled rotors and I’m thinking of fitting a bigger rotor at the rear as well. Stock it’s 160mm, so I’d like to make both 180mm. Is this KP421/180 adapter suitable?
Dobrý den, vlastním Cannondale si6 z roku 2019. Chci si pořídit lepší chlazené kotouče a uvažuji že bych rovnou dal i dozadu větší kotouč. V základu tam je 160mm, tak bych chtěl sjednotit oba na 180mm. Je tento KP421/180 adaptér vhodný?
Is it possible to use this adapter on a Seperior XP919 bike as well? It has a similar, if not the same, rear brake mount, or can you recommend another one so it fits? I need to increase from 160 mm to 180 mm.
Je mozne tento adapter pouzit i u kola seperior XP919? Ma podobny, ne-li stejny zadni uchyt brzdy nebo dokazete poradit jiny, aby to sedelo? Potrebuji zvetsit z 160 mm na 180 mm.
Which adapter should I use for the front brake on the Lefty on a Scalpel Carbon 4, model year 2018, to increase the rotor from 160 mm to 18O mm. If I increase the rotor diameter, won’t the Lefty be more stressed in torsion?
Jaký adaptér použít na přední brzdu na Lefty u Scalpela Carbon 4 r.v.2018 na zvětšení kotouče ze 160mm na 18Omm. Když zvětším průměr kotouče, nebude více namáhána ve skrutu Lefty?

Adapter bought for a GHOST Lector Base bike, fits perfectly and it’s one of the few adapters that offers flat mount mounting to 180 mm post mount (brake used SRAM G2 RSC).
Adaptér zakoupen na kolo GHOST Lector Base, sedí parádně a je to jeden z mála adaptérů, který nabízí flat mount uchycení na 180 mm post mount (použitá brzda SRAM G2 RSC).
