Community Workshop: Tubes, Tires, and Wheels

Flat tire on the trail? Heading out for a ride only to realize that your tube isn’t holding air?
Join us for a step-by-step guide on how to:

  • Remove and replace a bike tube and tire

  • Patch a tube

  • Reinstall a wheel

We highly encourage you to bring your own bike so you’re able to learn the techniques and tips on your personal rig. We’ve got plenty of bikes to practice on in case you need to borrow one. We’ll cover the necessary tools and techniques to keep you rolling!

Space is limited to 20 participants, so get registered!

This class is FREE to the community. If you would like to make a donation to Chain Reaction for attending the class, we’d suggest a $10 donation.

Community Workshop: Women’s (Re)Introduction to Biking
Jul

Community Workshop: Women’s (Re)Introduction to Biking

Calling all women/femme/trans/nb folks that have not biked ever / as an adult / in years, or just want to get more comfortable with biking basics.

Join us for a hands-on workshop where we’ll demystify the basics of biking - led by women. This might be the first of series to get comfortable with commute/city biking if there's interest!

We’ll cover:
✅ Bike Setup - basic bike fit, seat height, lights
✅ Shifting basics - when to shift, how to shift, types of equipment
✅ Communication - hand signals, verbal signals to indicate your planned route
✅ Q&A - anything that’s on your mind - sore rears, favorite routes, frugal gear, anything
✅ Group ride - a 2-3 mile loop through the park to practice signals, shifting, and try out the things we’ve learned

If you have a bike - bring it! It's okay if it's got some dust on it - this is a no judgment zone. We’ll have volunteers that can help you set up and walk through the functions of your bike. If you don’t have a bike, we hope to bring a few from the hub that you can try out.

Space is limited to 20 participants, so register here!

This class is FREE to the community. If you would like to donate to Chain Reaction for attending the class, we’d suggest a $10 donation.

Any questions, please reach out to us at CRBH.Volunteer@gmail.com

Sorry fellas, this event is limited to women/femme/trans/nb volunteers and participants.
