Going to a 1x11 setup?

[Osiris]

There's another Vendetta in my area whose owner has converted it to a 1x11 system, much like the XX1 system on my mountain bike. I believe the cassette he has on it is an 11-42T. Is there any advantage to this setup, or has it just become a fad among road riders after it became commonplace on mountain bikes?

I can certainly appreciate the advantage of reduced mechanical complexity, but my concern would be that on a road bike application, the jumps between each cog would be too abrupt.

Yes , you can change shoes, pedals, crank lengths, handlebars, x-seam and never have to readjust your FD cable.

A big disadvantage is spinning out on a downhill. Depends if you want to go fast or not. You could always stop pedaling and coast. The simplicity is appealing though.

Yes whilst the range is there the gaps are bigger. Looks good too
if aesthetics matter but overall practicality is compromised. Opinionated 2 x bias

Most folks don't shift "properly".
This means they use a chainring until it is too hard to keep using it, then shift to a lower chainring, etc.

The "optimal" shifting has one bouncing between chainrings to actually get the "less wide spacing". Most folks don't do this.

I have XX1 on my Silvio, chiefly because I hate double chainwheels. I have 11sp 10-42. I like the ratios, but I am not a serious racer trying to destroy the ego of J Perez. I could not manage that, even with the right ratios.

On the smallest cog, the chain was trapped by the dropouts. I put a washer on the drive-side end of the axle which pushes the forks out a tiny bit.

Why do SRAM sell such small XX1 rings? Their biggest is 40. I have a Garbaruk elliptical 42.

When I ride outdoors, I ride 99% of the in my large 53 tooth chain ring and I have an 11x28. I think with an 11 cog cassette most people should not have an issue with a single chainring unless they are really climbing some really steep stuff. It will probably have to be a trial and error for each person based on what they are going to ride. If you do need a little more leverage, you can slowly reduce your big ring down as well. You might sacrifice some top end speed, but rarely do people ride in their 11 or 12 tooth cog unless downhill or just really slow cadence. Higher cadence is much better for climbing and for your knees!

Thanks for all the responses. Because I often travel at very high speeds, I should probably stick with the stock setup.

There have been a couple of KOM's where I really needed that 11 tooth cog. One of them is a 1.2 mile segment with a -1% slope, where after a certain point I was able to pedal at 40+ mph, thanks to a tailwind. One of my KOM attempts was ruined when I experienced a mechanical issue and was unable to shift into the 53 tooth gear. I was spinning the pedals as fast as I could, but wasn't able to go past 32 mph. The memory of that incident haunts me to this day!

I have 1x10 (11-42 cassette) setup on my T50. For this bike it is enough. My low gears are low enough. And T50 is so slow downhill that you are not tempted to pedal there.
I would never put this setup on my Vendetta. I have 2x10 on the V (34-50 x 13-40). I like the range. I cannot imagine that I am out of gears at ~40 km/h. There is also another issue with 1x10 setup. There will be always crosschaing on some gears with only one chanring. This would be less issue if you have long chainstay.

Osiris whatever you choose it will make you faster. Enjoy that free speed. It’s a fantastic buzz.

1 x systems allow another design element and are gravel bike/ cross certainty. BB freedom lol

We are so lucky I think to have such great variety of choice as I look askance at my venerable 3 x 7 shod with original chain at 30 k.

 

[Rampa]

Also weigh the actual usable gears. Can you get 20 usable steps at equal increments with a double? You're probably down 2 right off because of large-to-large and small-to-small. How many of the rest are actually the same ratio?

I do remember Frank Berto's perfect logarithmic half-step to try and utilize all the ratios effectively. Electronic shifting systems can easily be programmed for shifting combinations most dual-ring set-ups call for to be used in a linear-stepped fashion.

Something to think about. I don't want to decide what anyone feels is best for them.

Just wondering... where did you find 10 speed 13-40 cassette? Thanks.

 

[tiltmaniac]

I made mine from aftermarket parts. Many cassettes are neither welded together for one piece. For those, you can get some things which change the cassette gearing by replacing a few gears.

I have taken Shimano XT 11-36 cassette, removed 11 tooth cog, added 40 tooth cog and 13 tooth locking ring both from Absolute Black.
I have ordered 42 tooth cog from Wolftooth Components for even larger range.

 

[cpml123]

Good to know. I was wondering how you made the 13 40 cassette. I never use the 11 tooth, even on my road bike.

x2 - works like a charm for Shimano but not SRAM. Find the 13T 1st position on Ebay for $10-15. My 40T is One-up and 42T WolfTooth. I thank Mr Youngblood for the solution.

That's a good idea

I don't understand. I have 10 sp. SRAM Apex shifters and X.7 derailleur and I cannot say that it deoes not work. Does Shimano work better? What Shimano?
