The ritual nobody advertises

Leg day, as your smart ring experiences it

This is the actual workflow of premium smart ring ownership, and it's the reason so many of them end up in a drawer.

5:58 pm

Other rings: off the finger, into the pocket, into the gym bag. Steps to the squat rack: untracked.

6:20 pm

Other rings: still in the bag. Working sets, heart rate, strain — none of it recorded.

7:15 pm

Other rings: back on, if you remember. A lot of people don't.

All session

CUDIS 002 Sporty: shell on, ring on. Titanium protected from bar knurling and dumbbell handles, session logged, recovery counted.

Why the shells exist

It's not a colour feature. It's protection.

Search any smart ring forum for "lifting" and you find the same thing: owners buying $10 silicone covers off Amazon to protect a $300–$500 device. There is an entire cottage industry of third-party sleeves for rings that shipped without one.

Your $299 ring shouldn't need a $10 bodyguard.— the reason the Sporty exists
🛡️
The shell is the armour

Medical-grade silicone over aerospace-grade titanium. Bar knurling, dumbbell handles and machine grips meet the shell, not the finish.

🤚
Better grip, less bite

The softer outer edge takes the pressure off the joint that a bare metal band digs into on heavy pulls.

Before you buy

The gym questions

🛡️
30 days to change your mind — and free sizing exchanges

Wrong size is the only real risk with a ring, so we took it off the table. Swap sizes free, or send it back inside 30 days for a full refund. Free shipping both ways.

Can I lift in it?

Yes — that's what the Sporty shell is for. It protects the titanium finish from knurling and metal handles and softens the edge against your finger. For maximal grip work where any ring is uncomfortable, most people still slip it off for the set; it charges in under an hour if you want to use that window.

Does the shell affect tracking?

No. The sensors sit on the palm side of the ring and stay in contact with your finger. The shell wraps the outer band.

Will the titanium still scratch?

Any metal you wear every day picks up marks. The shell is there to take those hits instead. Spare shells are inexpensive; the ring underneath stays presentable.

Does it track weightlifting properly?

It tracks the session, your heart rate response and the recovery cost. No ring counts reps. If you want live in-set metrics, keep a watch for training — the ring is what tells you whether tomorrow should be heavy or easy.

What if I get the size wrong?

Sizing exchanges are free, and we can send a physical sizing kit first. See the sizing guide before you order.

Stop taking it off.

12 shells. 5ATM titanium. 10-day battery. No monthly fee, ever.
