Vielo 1x Gearing Chainsets

1x for road bikes. Whoever heard of such a thing?

You’ve probably heard this debate in cycling communities up and down the land. So, it’s time to let you into a secret: Anything 2x can do, 1x can do too. You can’t argue with the facts.

Fact 1

One less chainring won’t compromise your ride

With chainrings from 38 to 50 tooth and cassette ratios from 10/36 you’ll find a near perfect match for your current 2x setup. Standard, Semi-Compact, Compact and Micro-Compact setups are all possible with 1x gearing.

Fact 2

Hilly rides are a breeze

If you ride a Compact or Micro-Compact for spinning smoothly up long, steep Cols there’s a 1x set that’ll do the job just as well. Simply swap your compact for a 44 chainring with 10/33 cassette or your Micro-Compact for a 42 chainring with 10/36 cassette. 1x is commonplace across MTBs, cyclocross or gravel, now it works successfully on road.

Fact 3

Riding fast isn’t a problem

Big gear riders, time for a big cheer. If you use a Standard 52/39 with 11/28 cassette we’ve a 48 tooth chainring with 10/33 cassette to get you flying. It offers the same gearing range with barely any differences in the intervals.

Fact 4

Fewer moving parts.
Less to go wrong.

With 1x is there is no front mech. This reduces weight which is great, and it also means no chain rub, no ghost shifting (with random chain jumps), and no cable issues. Simplicity, easy maintenance and you won’t drop a chain. What’s not to like?

Fact 5

Tradition is great.
Until it’s not.

Remember how disc brakes horrified the road scene a few years ago? Today they’re totally accepted. We confidently believe the same with 1x: For the old guard it’s the devil’s work, while visionaries see its real value.

Fact 6

Frames can perform better with a single chainring

Look at the space that two chainrings take up. This compromises the frame engineering and means less power can be translated into speed. By designing a frame specifically for 1x, we can do away with this compromise and give you more power for less grunt.

2x versus 1x
The head to head.

Still need convincing? The figures below compare the speeds you can reach at a set cadence using Standard, Semi-Compact, Compact and Micro-Compact.

2x Standard

52/39 with 11/28 cassette
52/11 at 90rpm = 54.9 km/h
39/28 at 90rpm = 16.2 km/h

1x 48 Single Chainring

With 10/33 cassette
48/10 at 90rpm = 56.2 km/h
48/33 at 90rpm = 17.0 km/h

2x Semi-Compact

52/36 with 11/30 cassette
52/11 at 90rpm = 54.9 km/h
36/30 at 90rpm = 13.9 km/h

1x 46 Single Chainring

With 10/36 cassette
46/10 at 90rpm = 53.8 km/h
46/33 at 90rpm = 15.0 km/h

2x Compact

50/34 with 11/30 cassette
50/11 at 90rpm = 52.8 km/h
34/30 at 90rpm = 13.2 km/h

1x 44 Single Chainring

With 10/33 cassette
44/10 at 90rpm = 51.5 km/h
44/36 at 90rpm = 15.6 km/h

2x Micro-Compact

46/36 with 11/32 cassette
46/11 at 90rpm = 48.6 km/h
36/32 at 90rpm = 13.1 km/h

1x 42 Single Chainring

With 10/36 cassette
42/10 at 90rpm = 49.2 km/h
42/36 at 90rpm = 13.7 km/h
