R-Core – “CAERUS”

Designed for olympic recurve shooters, the Caerus borrows elements from Hoyt’s great grip designs and adds details that make the hand sit comfortably on one position only.

The throat of the grip is reinforced on the thumb side and skinny on the index finger side, to “fill” the webbing properly and give you a hint on the correct angle, while the palm pressure area is flat at the bottom, curving towards the top. These features make the positioning of the palm a matter of feeling, so you know when something’s wrong!

* Leadtime for grips:


In Greek mythology, Caerus /ˈsɪərəs, ˈsiːrəs/ (Greek: Καιρός, Kairos, the same as kairos) was the personification of opportunity, luck and favorable moments. He was shown with only one lock of hair. His Roman equivalent was Occasio or Tempus. Caerus was the youngest child of Zeus.

In Greek Grip manufacturing, The Caerus is a grip designed in cooperation with multi-national-champion Alexandros Karageorgiou

This grip is mainly targeted to recurve archers and has an accented pressure point in the center of the grip, flattening lower on the palm.

    The grip is great it fits my Hoyt bow perfectly thanks

  2. Don S. (verified owner)

    Aris Rocks!, I’m a Multiple Repeat Buyer there is a Reason Why, Super Designs, Options, Fit, + Quality!. Many Thank’s!……

  3. Andres Gutierrez (verified owner)

    Amazing service. Before the purchase, during the process and after receiving it.

    The grip is absolutely amazing. Has changed the feeling of my shots for the very, very best and the Caerus was certainly the choice for my hand and bow style as recommended.

    I cannot recommend R-Core enough. There is no way that I would be moving riser without changing grip to an R-Core one.

    Aris job is superb!

  4. Alexander K. (verified owner)

    After trying a lot of grips on my bow this one is my favorite by far. Hand slides nicely in position and the lifeline ridge helps to control if hand is set correctly.

    Perfect service from Aris, he’s doing everything he can to fulfill his customers wishes and ideas.

  5. Nina (verified owner)

    The service is absolutely fantastic. Super kind contact. Every question has been answered. The grip is high quality and makes my shooting much more better.

  6. Stephen Keen (verified owner)

    Absolutely fantastic service. Had help and advice from start to finish. The grip is perfect.

    Aris worked with me to customize this grip for the new Mybo Wave XL, with a higher 50 degree wrist angle. The first grip didn’t fit properly due to slight changes in riser design compared to the older Wave riser. I sent pictures to Aris and he sent me a revised grip free of charge, and it fit perfectly!
    Grip positioning is very repeatable because of the slight palm curve in the middle, which creates a subtle pressure point.
    Terrific grip and excellent customer service!

  8. RAYMOND S. (verified owner)

    Fast delivery, fit on bow with bolt hole alignment, fit & feel of handle texture, looks all far exceeded my expectations! I am very pleased!

  9. Don S. (verified owner)

    R-Core/Aris are the Bomb!. All My Grips Have Fit Perfectly and the CAERUS line Rocks!……..

  10. Andy Comerford (verified owner)

    RCORE are an amazing company. Not only are their stock grips already very good but you also have true freedom of customisation to truly get “your” grip. Their service and attention to your product is second to none and the quality of what they produce is beautiful. I will happily purchase more of these grips for my bows in the future.

  11. Derk D. (verified owner)

    I love this grip on my bow. Really sets my hand in a different, consistent position which had a positive influence on my shooting. Also really like the color.

  12. raymond (verified owner)

    This is the second grip i have bought
    1st was for my old Hoyt Avalon riser
    It worked great. Great hand alignment!
    So when i got a new MyBo Elite riser at Christmas i just had to get a duplicate R core handle just like what i loved on my old Avalon

  16. Juha (verified owner)

    Excellent fit to my riser. Glass colour is much deeper in the thicker parts, which makes the grip seem almost duo-tone. Grip is quite thin between thumb and index finger. I’m happy with the grip and it’s quality.

    Super comfortable grip! Makes shooting easy!

    Having played around with personally customised grips for many years I wanted to go back to a standard grip in the high hand position. My bow manufacturer did not offer this option so I started searching bespoke grip suppliers. R-Core offered me exactly what I needed – simple but varied options for my riser. The grip varieties were exceptional and the customization options brilliant. Not only did I receive the grip of my choice, in the colour and material I wanted but the quality build is 2nd no none. On receipt the grip fitted my riser perfectly and feels great in the hand. My only criticism- and it is a minor one – is the length of time delivery took for the cost paid to deliver the item. I would not hesitate to recommend this company to any archer looking for a new grip and in fact have already done so whilst showing off my new grip to other club members.

  21. Dirk C. (verified owner)

    Love the finish. Perfect fit. Excellent service: arrived 5 days after order placed! (US>Australia)

  22. Markus (verified owner)

    The Caerus is simply the best grip I have ever touched. My hand slides so well in the same place over and over again and it is so easy to find the right preassure point. I am in the sport for 1.5 years now and far away from being a professional but my groups tightened up immediately.

  23. Markus (verified owner)

    For sure the best grip I have been using so far. Perfect fit shot after shot – I really recommend this grip!

  24. Cody Greenwood (verified owner)

    I love your grips. I wish they were marked so I knew what each one was

  25. Nina Caulton (verified owner)

    Love this low grip, my shot feels more powerful and it fits comfortably in my hand

  26. Kieran Closs (verified owner)

    can’t give high enough review, exactly what I ordered will definitely order a spare for my riser soon very well made 😊

  27. Christian Lohmann (verified owner)

    To solve my bow hand issue I ordered two different grips from R-core for my W&W CX7. I have not yet decided which of the two grips I keep but the life-line indicator on both grips is of good help to improve my form. Fast delivery even to Japan.

  28. bob schuitema (verified owner)

    I picked up the caerus in a compound like low grip with hex pattern and a lifeline. It sits on my win and win black wolf riser and was a perfect replacement for the tennis wrap that I was using before. Could not be happier with the purchase.

  29. Peterjohn Sargent (verified owner)

    I liked this grip so much I bought another for my second bow. Comfortable and sits nicely in the hand.

  30. Gerardo Joaquin (verified owner)

    Awesome grip!!

  31. Fabien Dellamore (verified owner)

    very good produce and contact of quality with the manager

  32. Martijn H. (verified owner)

    It’s my first RCore grip and it feels absolutely amazing! The quality of the plastic grip is outstanding and feels very solid in my hand while shooting, which is definitely a huge upgrade compared to my stock grip 🙂

  33. Olivier Courtin (verified owner)

    The Glass one is too fragile : I broke it by positioning it on the handle – I recommended a normal one and it’s OK now

  34. Olivier (verified owner)

    the 45 ° version is very good: may not be raised enough at the level of the thumb

  35. Ralf Stegmann (verified owner)

    Alles super abgelaufen! Gerne wieder.

  36. Joseph F. (verified owner)

    Awesome grip. The texture really helps with finding my lifeline. Perfect fit on my bow too.

  37. Tim Stewart (verified owner)

    I’m fairly new to archery so when I decided I wanted to get a replacement grip for my AFTX riser was unsure what to go for but Aris was very helpful and advised me. Have to say the new grip is fantastic and has really improved my grip positioning and feels really natural to hold. Would definitely recommend.

  38. Peterjohn S. (verified owner)

    Just received my 5th R-Core grip (1 plastic, 1 wood, 3 glass). If that’s not enough recommendation, all have been superb finish, quick delivery and R-Core extremely helpful when I made an order error, responding and correcting it immediately saving me major embarrassment! These grips are not ‘eye candy’ they are professionally designed and made – Jake Kaminski obviously agrees! My wood grip is my favourite – the web pictures don’t do the final product justice. Highly recommended.

  39. John Winterbottom (verified owner)

    Very good, I have used R Core before.
    I further improved my grip by dipping it in a high quality rubber dipping paint.(same colour of grip). 2 coats have made a good grip absolutely superb.
    The coating doesn’t mask the lifeline ridge or chequering on the grip but gives a wonderful soft feel. R core should look at this on their hard plastic grips.That said, R Core offer fairly priced custom grips with good delivery times.

  40. KAIFEI L. (verified owner)

    Unique grip, different feeling compare to other grips. Really good quality, and the color match my riser very well.

  41. Renato V. (verified owner)

    For real. A good shot starts with a safe, comfortable, balanced grip in the archer’s hand. I found all this with RCore. a truly excellent grip. Nothing to do with the MK-Kore standards in both wood and rubber. The one I took is in glass. In addition to being beautiful, it is ideal for the Olympic arch. It does not need any other modification or to be wrapped with tennis tape. Communication, speed and production and shipping are also very appreciable. a beautiful, pleasant surprise to have met a very, very good company for my great passion for archery

  42. Sebastien D. (verified owner)

    Excellent quality and very good communication. There was a problem with the first one and I got in 2 days a replacement which is perfect 🤩

    I like the look and feel of the glass. The Caerus fit my bow like a glove, but not perfectly for my hand. I’m a 5’6” female with medium sized hands. I like the palm line and I had to add the provided grip tape and additional grip tape on the side to prevent slipping, which I also took as a sign that I wasn’t getting a consistent grip due to fit. However, I like the feel off the grip tape over the diamond pattern. Overall a nice grip, but just not the perfect fit for me.

    As someone who 3D prints professionally and recreationally, the quality of the printed grip I received from R-Core was top notch. The CAERUS grip was a hit and miss both for me. While it has excellent features for the palm and the index finger indent, it has a very open thumb shelf. I struggle to find a consistent position for my thumb. This is nothing a bit of Sugru won’t fix. It is a solid base to add your own modifications to.

    The “cat tongue” like unidirectional texture grip is amazing. It is holding up great. You don’t really feel it once you start loading. I find that this is a must have feature for anyone with a heavy bow + stabilizer setup. Great grip. I will definitely buy again.

    I shoot a 27” Hoyt Formula RX and shoot tournaments. I was not too happy with the regular grip as supplied by Hoyt so I looked for an alternative. After watching the Jake Kaminski YouTube channel I thought I would give the R-Core grips a try. So I purchased the plastic version.

    After shooting the Caerus grip for a couple of weeks now, I feel confident in stating that I am very happy with it.
    It helps make my groups tighter and more consistent. I might even buy another one, but in wood or glass.
    I can wholeheartedly recommend the R-Core grips based on just this one grip I have. If I change my bow, I will replace the standard grip with one from R-Core.
