Are you still happy with the repair?
It worked well yes, I was riding as hard as before 24h after the repair.
I did check regularly the fix and around when cleaning the bike initially, but then forgot about it.
Unfortunately, I broke the frame about a year later( seatstay in 3 parts beyond repair ).
If you are lucky on the position of the crack, it is quite easy for a DIY repair, I guess compared to reshaping/welding aluminium or titanium.
I would do it again for sure if it happens again.
@Jerryno, good reminder!
I was surprised too to see the guy doing the sanding indoor and without mask.
The same applies when cutting bars or a carbon fork tube.
I do that outside, caring about the wind, with gloves, glasses and mask.
Probably overkill, but it doesn't last long.
