Electric Conversions of "Manual" Bikes / Re: Bafang PAS senso
« Last post by lamonabike on Today at 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

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

« Last post by John Saxby on July 06, 2026, 02:26:04 PM »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!
