Nice component.

This component is well manufactured and the right size for the bosses on my Pashley Paramount. Note that I found that when fitted there wasnt enough room for the activation switch on my Nordlicht 2000 dynamo which extends to the right of the mounting bolt. Ive now ordered the xtra long version instead which will hopefully provide a better fit.

Hi I have a Dawes discovery with two bolt holes on the inside of the fork leg just under the v brake mount. The holes are 15mm apart. I'm assuming Dawes used to make a suitable mount but I was wondering if one of these thorn ones would fit. Are you able to advise me on whether I should go for the extra long, the regular or the T shaped Dynamo boss mount? Cheers

Any of the 3 brackets we sell should be compatible with your 15mm mounting holes, we don't however know which would be most suitable for the forks of your Dawes Discovery I'm afraid. You need to check with the mounting holes on the forks compared to where the dynamo needs to sit to work out the best shape of bracket. If you're still not sure then the extra long is the most universal as it has the greatest range of adjustment.
