Mysterious bracket on the seat stay

Hello everyone,

Can someone help out with this mysterious bracket located on the right side of the seat stay?

Does the frame have tabs for disc brakes? If so, it could be a hose/cable guide for if you fitted it with discs.

The frame does have all the necessary tabs for discs, but wouldn't the bracket be made to catch a round cable/hose? This one looks like something's suppose to slip into it.

True, but it looks like you could get a cable tie under it between the welds, to wrap over the top hold the housing/hose down. That was what made me think it. I'd say generator mount, but the cantilever brake boss would get in the way of the actual generator if it was. What's the frame?

Wait, the rest of my brain just activated, that's nothing to do with disc brakes whatever it is, it's on the right-hand side, discs are always on the left. I'm stumped now...

I thought it might be a dynamo base, but this specific models is designed and comes with a dynamo-hub... I'm stumped too!

Actually, I just noticed this bracket today (after 2-1/2 months) when I was checking to see if I can place a wheel lock (https://www.axacompany.com/EE/en/axasite/products)

Appears to be a bracket for a bottle generator, maybe something Euro specific.

I can't tell from the photo, but another possibility is spare spoke-holder- is there another little clip a spoke-length away?

Edit: Oh, it's on the inside of the frame? A sensor-holder for a specific computer? Never heard of such a thing, but no reason it couldn't be done. Alternate style of brake?

Looking some more, I would say probably a mount for a bottle generator. In the Maintenance Manual, Photo 15, available on the website, they show a bottle generator, but you can't really tell how or where it's attached. I think lights are required on German bikes sold in Germany. https://www.corratec.de/
On the bikes in the pictures, I can't see anything located there, but then, I don't see a bottle generator located anywhere else, either.

Upon closer inspection of the older series, I too believe that it is a base for a B&M bottle dyno, probably an option on older models since hub dynos where much more expensive... here's the Shape 08 which has the bottle dyno:

Reminds me of the Novara Safari my girlfriend picked up this year. Previous years models had disc brakes, and although hers came with V's, the hubs and frame are set up for discs. In fact, even the rear rack that came with it is a disc brake model, which looks a little funny with its "wide stance" on a V brake equipped bike. Although with hers the fact that it is disc ready could be a selling point to some, I suspect with both your and her bikes it just isn't worth the $ to change the production line to remove these details, especially if there is a chance in the future they might be utilized again.

@Medic, that would explain why my bike has a rather wide rubber-covered spacer on the left side of the rear axle. To be perfectly honest, I'm quite satisfied with the v-brakes and their performance, especially since I use the bike for commuting purposes.

Edit: It should also be reasonable easy to install disc brakes since all the necessary hardware mounting points are in place.

Just got the official word from the manufacturer... it really is a bottle-dynamo base for models which don't have the dyno-hub. Nice to know!
