How to measure the diameter of your handle bar

18 April 2016 1:50:19 PM AEST

Handlebars come in all weird styles and sizes, but we’re here to help make choosing the right size Oi bell for your bike(s) easy. After all bell size does matter!

Watch this video to understand where & how to attach your Oi bike bell.

Measuring bar diameter

The easiest way to measure those handle bars is with a set of digital or vernier scale callipers.

If you don’t have callipers then you can use a simple measure tape. Just wrap around the bar at the point you want to attach the Oi to get the circumference size and then divide by pi (….mmm) to get your diameter e.g. 99.9mm / 𝜋 = 31.8mm.

If you have no tape, then use a piece of paper (or string). Same as above, just wrap the paper around the bar at the point you want to attach the Oi, make a mark with a pen where the paper intersects and then measure against a ruler. This will give you the circumference and to get the diameter just divide by pi. Easy.

Most of the time the area you'll be attaching the bell to will be either 22.2, 25.4 or 31.8mm and can generally be separated in to the below categories. 

-  Road Bike – Handlebars generally come in two clamp sizes 26mm (older style) and the newer ‘oversized’ 31.8mm. The area where you attach the Oi bell will most likely be either 25.4mm or 31.8mm. 

-  Commuter/Cruiser Bikes – These handlebar sizes do vary due to the wide variety of styles, however most bar sizes would be either 25.4 or 31.8mm

-  Mountain Bikes – Handlebars generally come in two clamp sizes 25.4mm (older style) and the newer ‘oversized’ 31.8mm. On some bars there will be a bulge in the middle and the bars will thin out towards the brake levers. If you want to attach your bell here, then please make sure you measure as it could mean you move from a large sized bell to a small. For instance the grip area on some of these bars will be 22.2mm, whereas the bulge is 25.4mm.

-  BMX – Always 22.2mm.

Tip : 
- If your handlebar is any bigger than 22.2mm then you will need to choose the larger sized bell. The Larger Oi will come with shims that will allow you to attach the bell to bars 23.8, 25.4 and 26mm.
- If your handlebar in the middle looks 'normal sized', it's probably 25.4mm.
- If your handlebar looks overly big in the middle, it's probably 31.8mm.

Jo Celso is a cycling legend!

15 January 2016 4:29:58 PM AEDT

Jo Celso of Team Cinelli Chrome beat Hodgkin's lymphoma only to be sidelined two years later by a debilitating crash. Here's what the San Diego native has learned about resilience—and how she returned to riding better than ever.

After a race, I was rubbing my shoulders and noticed a tiny bump on my neck. I thought it was a muscle strain. My doctor did a biopsy and took out a lymph node. A couple of weeks later I found out I had cancer.

I posted on Facebook: I have cancer. WTF. People thought it was weird, but it's stressful to tell one person that you have cancer. I didn't want to go through it with everyone. It would have been too emotionally draining.

Chemotherapy was a roller coaster. Some days I was incredibly depressed. If I hadn't had cycling, I would have felt aimless. A lot of my teammates encouraged me and asked me to hang out. The community was great.

I rode multiple days a week, up to four hours at a time. I'd feel fine, but once I got out there, the same effort cost a lot more energy.

Yeah, I thought about giving up. My body was trashed after chemo. It took about three months before I was at baseline again. You have to realize it's going to be a long climb to where you were.

On the bike, part of getting really good is losing a lot. You have to face challenges and come back, and learn to not become defeated.

It blows me away how resilient my body is—to be weak and bedridden, only to build back to an even stronger version who travels around the world to race bikes.

I'm speckled with scars from road rash and chemo, but I'm thankful for the vessel I'm in and how it enables a beautiful life for me.
