Re: 1x11 gearing on a bent

The Deore Shadow RD M592 9 speed "DOES" have a "B" stop screw. Mine does. Looking from the rear there are three(3) screws, on the left you have the High & Low adjustment screws one above the other, and to the right (the other side of the gear cable) is the "B" stop...

Re: Cycling for Disabled People.

The new Hase Trigo has a higher seat and is good value, although the options can mount up. Also no suspension. Hase list "Get Cycling" in York as having a Trigo demonstrator. Interesting video showing its versatility here, https://youtu.be/JtAQ7KUCrYo

Re: 1x11 gearing on a bent

I was right, the shifting is much improved with an 11-34 cassette. I think there is something non-standard with the RD mount on the drop out of my Nazca. THe 12-36 cassette should work with the Shadow Deore RD. I also found that an 11-34 cassette did not work with an SRAM X9 RD, even with the B-scre...

Re: 1x11 gearing on a bent

So, the poor shifting wasn't caused by a worn chain. It was caused by the RD mounting bolt loosening :shock: Anyhow, I now have new chain fitted (old one will be kept for re-use) and the RD bolt torqued to 10Nm along with a washer to stop the bolt protruding on the inside of the chain stay and fouli...

Thanks, that's reassuring to know. Yes mine also came with a washer zip tied to the drop out but I wasn't sure what it was for.

Re: First ride

Did you use a washer on the RD mounting bolt? On my Nazca with its thin dropouts, the mounting bolt protrudes on the inside of the chain stay and fouls the chain when on the smallest sprocket- it can catch on the chain pins. I have now used a 2mm thick washer between the mounting bolt and the dropou...

Re: 1x11 gearing on a bent

My conversion to a 2x9 is work in progress. I've installed a wheel with an XTR hub, Deore M592 shadow RD and Alivio shifter with a 34/48 compact double. Whilst the shifter technically can change 3 sprockets at a time, in practice my thumb can only manage 2 at a time. The shifting isn't very slick wi...

Re: First ride

It looks very laid back so surprised when you say the ride height is on it's highest position. Might be the photo. Is this the large frame?

Re: First ride

Looks good. I went with the fire-red for my Nazca Paseo but I was very tempted by the apple-green. What rear derailleur and crankset have you fitted?

Re: 1x11 gearing on a bent

David Gardiner of Laid Back Bikes is trying a 1*12 setup on his demo Nazca Fuego. You could ask him how it is going. I wonder if that's using Sunrace's 11-50T 12-speed cassette. I can't see a shifter with a gearing indicator for that though and I wouldn't like to be shifting blind on a 'bent. My pr...

Re: 1x11 gearing on a bent

I agree large chain rings+large sprockets are more efficient because of lower chain tension, and also less friction because cogs below 14T have increasing friction losses. I saw some figures which were a deterrent to using 11T or smaller in particular. I shall give a 34/48 compact a try with a 12-36...

Re: 1x11 gearing on a bent

There seems to be a consesus that having a wide normal range with granny option of some kind is good. I've been playing with gear calculators configuring for a compact double and a wide range 10-speed cassette (avoiding the expense of moving to 11-speed). I like the look of a 34/48 double and 12-36T...
