Electric Conversions of "Manual" Bikes / Re: Bafang PAS senso
« Last post by lamonabike on July 08, 2026, 06:03:38 AM »
I thought you might be interested to hear the latest on this.
I bought a left handed PAS sensor for £12 or so and installed it on my Thorn Raven crank.
It went on okay but as I was installing the crank arm back on it felt like I was crushing the sensor.
Just been out for a short ride and the turning of the cranks feels different.
I’m still not convinced it will all work but I think I just need to go ahead and buy the full kit and see what happens.

Thorn General / Re: Kickstand Options for a Mk2 Sherpa?
« Last post by RonS on July 07, 2026, 04:37:26 PM »
I use the Greenfield Stabilizer on my Raven. Holds up the bike with a full touring load, and attaches to the frame at a very strong point.

Thorn General / Kickstand Options for a Mk2 Sherpa?
« Last post by Binky on July 07, 2026, 10:25:08 AM »
I'm about to purchase a secondhand Thorn, I believe it is a Mk2 Sherpa with derailleur gears. My wife will be using the bike as well as me for local/casual use and insists on a kickstand of some sort.

I know that Thorn's warranty won't apply as I'm not the original owner but I would still rather not attach anything that risks damaging the frame or paintwork.

What are my options for attaching a kickstand to this bike whilst doing as little damage as possible? We'd prefer something attached to the bike rather than a click-stand. Thanks

Hi, Julien

John is partly correct. I have used Panaracer GravelKing, but they were the slick version, and size 42-584 / 650B, used on my other bike, not a Thorn. They were wonderfully supple, with a great ride. They did wear out fairly quickly.

I would have tried out the GravelKing SK in 26X2.10 on the Raven, but I could not find any at a reasonable price when I replaced my tires. I instead purchased Schwalbe Marathon Mondial 26X2 with the folding bead. I have been very happy with them, and will probably replace them with the same when required, assuming Schwalbe doesn’t discontinue them also.  They currently have travelled 12,000km, with 5000km of that heavily loaded tours, and there is still lots of tread remaining. The only negative I have to say about them is that they buzz like MTB knobbies on tarmac. The newest versions appear to have a slightly different tread, and perhaps they will be quieter. I see there is also a new Marathon PRO Mondial now, for about €15.00 more.

Good luck with your search

Jul, I forgot to mention the Panaracer options:  They offer a 26 x 1.75 Pasela PT, but also, in the Gravelking range, a 26 x 2.10.

I tried the Gravelkings on my Mercury in 2025 (650 x 48 mm, 46 actual).  They worked very nicely on tarmac and easy gravel.  BUT, I had to remove my rear tire when the expensive TPU tube valve said "Enuf!" after 500 kms.  At that point, I found that remounting the Gravelking on my tubeless-compatible rim was beyond what my arthritic thumbs could manage.  (Front tire, with my Thorn alloy rim, was no problem at all.)

That problem is mine, obviously -- but if that sort of thing is no problem for you, I'd recommend looking at the Gravelking option.  (My cycling buddy, Ron Séguin, who posts here, uses 26" Gravelkings on his Raven.  I think they're 2.00, but am not sure.)

Hope that's helpful -- good luck!

John

The measured weight of my 2.0 x 26 Dureme is 600g (agrees with Martin) but Schwalbe quote 750g…….

What about Panaracer Gravelking SK ?
26x2’10 for 610gr each

Not looked at those, from UKTony's description they seem to be a bit more like Duremes than Supremes (more grip off road, more rolling resistance and a bit heavier than Supremes). The weights I noted for the 3 tyres I use most in the 559x50 size are :

Supreme 565g
Dureme  590g
Mondial folding bead 740g

And the Continental Contact Urban are 590g, probably because of the wire bead, I haven't found them with folding beads in 559x50, but they exist with folding beads, at least in the 16" size for Brompton folding bikes. 

The website https://www.bicyclerollingresistance.com is usually quite good at comparing different tyres, but sometimes I haven't agreed with their findings, notably when I try to extrapolate their results to another size of the "same" model of tyre.

There are a lot of good tyres in the "modern" sizes 29" (= 700C) and 27.5" (= 650B) , but choice is much more limited in the "old" 26" (= 559) size.

The irony of that is that I can now find very nice tyres for my ancient 650B utility bike.
