Rapidé OVL™ Ring 104BCD
R549.00 – R579.00
Now Available In 32t/34t/36t
The Rapidé OVL™ Ultralight Ring gives you better traction, especially with climbing, riding in sand or loose rock, by smoothing out the torque you deliver to the rear tire.
Where your pedal stroke is weakest you have the equivalent of 2 teeth less on the chainring, and where you have the most power you have 2 more teeth. The radius of the chainring is constantly changing. The torque needed to turn the cranks is constantly changing to better match your power output. The Rapidé OVL™ Ring maximizes the part of the pedal stroke where power is produced, and minimizes resistance where it isn’t, allowing you to get on top of a gear.
Made with super stiff and very light weight 7075-T6 alloy for flex-free power transfer and long life. The Rapidé OVL™ Ultralight Ring is a perfect Single Speed chainring as well. It features our enhanced narrow-wide tooth profile for incredible chain security plus an elliptical shape to maximize traction, power and efficiency.
Note: Not compatible with half-link chains.
* Mountain biking rattles bolts loose – use a quality thread lock compound to prevent this. Pay particular attention to things like chain ring bolts – a lost chainring bolt can lead to chainring failure.
* We recommend torquing chainring bolts to 6-8nm and periodic inspection.

FAQ
Q: Can you guarantee my chain will never come off?
A: Almost! When combined with a clutch-type derailleur, chain-drop will not be an issue for most riders.
Q: What chains will Narrow-Wide chainrings work with?
A: Any 10, 11 or 12 speed chain will work. We always recommend a clutch-type rear derailleur for the best chain retention. However for general riding without a clutch type drops are very rare given a properly sized chain.
Q: Can I use Narrow-Wide chainrings with a front derailleur?
A: Narrow-Wide chainrings will NOT allow shifting with a front derailleur as they are specifically designed to stop the chain moving off the chainring to another cog.
Q: What is an optimal chainline for 1x?
A: 49-50mm is centered on the cassette and that is optimal for a rider that used the whole range of the cassette in a normal distribution.
Q: Can I use a Narrow-Wide chainring on my single speed?
A: Yes, they work just fine for single speed but have no advantage over a “normal” chainring unless you are using a tensioner in place of the rear derailleur.
Q: What bolts should I use for 1x chainrings?
A: You can use single chainring bolts of around 5mm depth or for best performance double chainring bolts with our spacers will give an optimum chain line. Our 30t round and 32t oval narrow-wide chainrings have built in spacers and are threaded, you only need the threaded portion of your existing chainring bolt for these.
Q: How do I determine what BCD chainring I need?
A: Often the BCD is printed or engraved somewhere on the original chainring. If not you will have to measure the distance between the bolts across the center of the cranks.
Our chainrings have a 104mm BCD which is the most common size. Always check first as there are several brands of cranks around that have different BCDs on the same model depending on the chainring ratios.

I bought this to replace a worn out big-brand oval chain ring I have.
The quality is excellent as with all other Rapide products I have used.
The first ride impressed me most as in the past there has always been some noise and rubbing initially as the chain ring “wears in”.
This one was dead quiet and smooth from the get-go.
The threaded holes and built in spacers make installation such a pleasure. (I got the 32t version)
Highly recommended.

The Oval pedal stroke feels amazing!
The 32T product is well made, easy to install and fantastically priced.

It’s true……the oval will help!!
Awesome piece of kit. Run the 32T with the Rapide Sunrace 11-42 cassette, and I’ve never run out of gears. Use that combo for the likes of a 50km with 900m of climbing, very comfortably.
I’m an average rider who would do the above distance and ascent in about 2hrs30mins.
For a 50km, with less than 900m of climbing I’ll use my 34T. Again, without running out of gears at any time.
Solid pieces of kit too.
Tiniest bit of settling down rubbing, but then again, what combinations don’t take a bit of time to settle.
Will I move from this combo/kit……………………unless I win the lotto…..NO WAY
Delivery felt like 20 minutes after I had hid submit, on my order……
Team Rapide, you guys ROCK!!!

I love my oval chaining. I have just purchased my 2nd 32T. Much less slipping on loose steep climbs and feels faster on flats . I tried out my round one again and took it off after one ride!!
