Overall Product Rating 4 / 5
Expensive but it works

I recommend this product
This is for a Vitus Substance Sora Adventure bike. I simply counted several threads and measured with a ruler to get thread pitch which was 1.5mm. Measured the axle length not including the non-drive side lump which incorporates the unscrewing lever on the axle. That was 165 mm. I used the thinner of the 2 washers that come with the axle on the non-drive side and another thinner one on the drive side to ensure that when you screw the bobbin into the drive side end of the axle, the washer (and thus the dropout) is gripped by the bobbin- as opposed to just screwing into the axle end if the 2nd washer wasn't there. Just done a 270 km trip with 25 kg payload, including the BOB, where everything worked well

Is this the right one?
14 Jun 2018
Using your guide, my axle is 167mm with a pitch of 1.5. The closest part you stock is the BOB112 (159-165mm). Is the BOB112 OK for me?

Also, could you tell me the diameter of that part of the bobbin that the trailer hooks onto. Mine is not a Bob trailer and I need to check it will slot onto the attachment point.

Many thanks
Hi there,

You would need to discuss this with the manufacturer of your bicycle, we would not recommend that it would be suitable.
