Would look a little wider compared to the Moulton (42mm wide) stock ones.



I tried non stock ones like this, which were about half the price but a nightmare to fit.




You can't beat the stock German made SKS ones. That said Thor's ones do look nice. The stock ones also come with the correct spacers for the back wheel to space it evenly away from the rear frame and the shaped stays for the front, (Thor's front stays won't work), which fit over the suspension assembly.





Can be found on the Moulton Accessory pages. Scroll down to the 20" ones.
