Training gear for athletes who put in the hours.

Delo Sports is the home of Tennis Tutor and Ripwave. Together they make racket sensors, skateboards and robotic trainers. You can buy everything here and pay from your Ethereum wallet.

Who we are

Delo Sports, Inc. is a group of small, focused equipment makers. Each company designs for one kind of training and leads its own engineering. Delo Sports handles the shared work: manufacturing partners, quality control, fulfilment and this store.

We started with a simple observation. Players don't improve when they own more gear. They improve when they get more good repetitions, in less time, with honest feedback on each one. Everything we sell has to do at least one of those things, whether it's a ball machine running a crosscourt drill or a robot arm testing your first step.

We accept payment in ETH because many of our customers already keep money in a wallet, and because paying on-chain removes card fees and chargebacks from a business with tight margins. We pass those savings on in our prices.

Tennis Tutor

Hear what every hit tells you.

Tennis Tutor puts a sensor on your racquet that listens to the vibration of every hit and sends it to the Tennis Tutor iPhone app. The app shows how hard and how clean each hit was, so you can tell a sweet-spot strike from a frame shot. We sell the court gear to go with it: a ball launcher, rebound walls and targets.

Ripwave

Boards and robots for balance, footwork and reaction.

Ripwave makes skateboards built around its wave technology, alongside robotic trainers that stay fixed in place while their decks, arms and lights move, so you have to react. The Wavetrain platform rocks beneath you in a steady train of waves. Skaters, tennis players and field-sport athletes use them to train the balance and footwork their sport depends on.

How paying with ETH works

  1. Add your shipping details

    We ship to the address you enter at checkout. The order total is fixed in dollars.

  2. Lock an ETH price

    We convert the total to ETH at the live Chainlink rate. That amount is held for 15 minutes.

  3. Confirm in your wallet

    Your wallet asks you to approve one transfer to our address. We never ask you to sign anything else or approve token spending.

  4. We ship

    After a few block confirmations the order is marked paid. We email you tracking details when it ships.

Payments go to our wallet on Ethereum. Check that the address in your wallet matches this one before you confirm.
