Fizik Antares R3 Open K:IUM Saddle


With an anatomic cut-out shape and advanced technology, materials and craft, Antares R3 Open is a performance road saddle for riders who want a medium saddle profile and a cut-out to avoid pressure and numbness.

Just what I was looking for & Great service

After debating for months about which saddle to try after years of using the stock saddle that came with my bike I took the plunge for this Fizik Antares R3 due to their useful Spine concept system. Initially brought the standard width one but straight away realised something was not right. Then ordered the wide version from ProbikeKit too (which arrived super quickly) and that made all the difference. ProbikeKit refunded me the money for the standard one fast and easily. The saddle certainly has taken a bit more setting up to get in the exact right spot as never realised how much of a difference too far back and height can make but finally found that spot now. Happily doing 60km cycles without a fuss and can't wait to do some epic 200km cycles again.

Nice Improvement to Antares

I have regular Antares on several of my bikes. For my bike on the trainer - where you are constantly seated - I decided to try the Open version of this saddle. It has worked out great alleviated a little bit of the pressure and has made time on the trainer a lot more enjoyable. I would recommend it highly.


I've been a longtime Selle Italia (Flite, SLR, X2) guy, but I decided to try the Antares to see if I was missing out on something that might work well for me. So far (~400 km) the Antares has worked *really* well for me. No perineal pressure, no sit-bone pain, just a comfortable, supportive, and good looking perch.
