I noticed that I can fit 40c rear wheel to my dolan pre cursa. I recently got a new track bike and have no track use for the dolan anymore. Due to the large wheel clearance I was thinking of getting a new fork and turning the frame into a single speed cx bike. I know that the track geometry isn't ideal but I already have a geared cx bike which I use for my "serious" cx rides.
So I discovered the thing showing in the picture that would allow me to install a disc brake to the bike. Is that thing safe to use with the frame (7005 aluminium if I remember correctly) since the frame is clearöy not designed to be used with a disc brake in the back? I assume that the frame could take it, after all there are aluminum mtb frames that have disc brake at the same spot.
If the thing is too risky, I will just use the bike as a fixed cx bike but it would be nice to try to use a freewheel instead of a fixed cog.
