A banana at the top of a climb is basically a five-star meal. πŸŒπŸ˜‚

But in all seriousness, on-bike nutrition is something a lot of cyclists overlook until they bonk hard on a July ride in the heat.

A good rule of thumb: eat before you feel hungry and drink before you feel thirsty. Simple carbs every 45 minutes on longer rides make a huge difference. 🫑

The cyclists and runners of every household, summed up in one photo. πŸ˜‚πŸš΄β€β™‚οΈπŸƒβ€β™€οΈ

We love that cycling brings people together, even when one person is pedaling and the other is sprinting just to keep up.

However your crew moves this July, the important thing is that you're out there doing it. 🫑

The ultimate July setup. πŸ•οΈπŸš΅

Truck camper, bikes on the back, mountains on the horizon, and absolutely nothing on the agenda except finding the best trails you've never ridden. This is what summer was made for. 😎

If your summer plans involve hauling bikes to new places, stop in and let's make sure your gear is dialed in before you hit the road!

Summer break means it's officially bike season for the whole family. β˜€οΈ

June is one of the best months to get everyone set up with the right bikes and helmets before the riding really picks up.

A properly fitted helmet is one of the most important things to get right, especially for growing kids. Sizes change faster than you'd expect. 😬

Did you know tire pressure is one of the single biggest factors in how your mountain bike actually feels on the trail? 🚡🌿

Too high and you lose traction and get a harsh, bouncy ride. Too low and you risk pinch flats and sloppy handling.

Most riders are running the wrong pressure without even knowing it. A good starting point is 25 to 30 psi for most trail conditions, but your weight, tire width, and terrain all affect the sweet spot. πŸ™Œ

The climb is hard. The view from the top is always worth it. πŸ’ͺπŸš΅β€β™‚οΈ

One thing that separates riders who improve quickly from those who plateau: getting the right bike fit before summer really kicks in.

When your reach, saddle height, and handlebar position are dialed in, hard climbs like this one actually become manageable instead of miserable.

June is a great time to get a fit check before your summer rides ramp up. Ask us about it next time you're in. 🫑

Your June weekend plans just got a whole lot better. 🌲

Pack a small backpack with water and a snack, grab the crew, and find a paved trail or quiet road through the trees.

Riding doesn't have to be intense to be amazing. Some of the best rides are the ones where you just go and see where the path takes you. 😎

This is what finishing a goal ride feels like. πŸ™ŒπŸŒ„

Whether it was your longest ride yet, your first time back after a long break, or just a really hard climb you finally conquered, these moments are what cycling is all about.

June is a great time to set a new two-wheel goal for yourself. What's on your riding bucket list this summer? Tell us below πŸ‘‡

Quick June riding tip. πŸŽ§β˜€οΈ

If you ride with earbuds, keep one ear open so you can stay aware of your surroundings, especially on shared paths and streets.

It's one of those small habits that makes a big difference in safety.

Also worth knowing: proper saddle height is one of the most overlooked setup details for casual riders, and getting it right can completely change how comfortable your rides feel. 🫑
