Re: What tyres (possible unicorn content)?

Spa are listing Marathon Racer and Supreme. Supreme is almost slick. Racer has a shallow tread, about 1mm. deep, and they can "let go" without warning on mud or even wet grass. …. gets ridden on gravel as well as tarmac If the gravel is loose, I don't think a bit of tread will help; I thi...

Re: HPV grasshopper rear wheel offset ?

The grasshopper is a bike. Maybe the rear wheel came from an Ice trike.

Re: HPV grasshopper rear wheel offset ?

Surely a grasshopper rear wheel should be dished as normal so rim is centred between dropouts.

The Spa XD-2 goes down to 160mm. £25 without rings. £5 for bolts to match.

Re: 1x11 gearing on a bent

I reinstalled the 12-36 cassette, adjusted the B-screw and all is fine. I changed the rings on the compact double to 33/44. I am able to start in bottom gear on the big ring ok, and all the gear changes work well. The steps in gears are comfortable. Compared to what I had with the SA CS-RK3 I have b...

Re: Is there a perfect bike for commuting?

I have found that swept back flat bars and a sprung saddle improve comfort enormously, so those aspects of dutch-stye bikes makes sense to me.

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...
