Cracked Tube Repair
Just got back from a ride and noticed a crack in my steel single speed mtn bike. Looks like I was using a seatpost that was too short and it punched its way through the tubing. I haven't stripped the paint, but you can see the crack as a black line on the seat tube.
I'm wondering what people's opinion might be for trying to fix it by brazing the joint. I was thinking of brazing the crack, then fashioning a "patch" over the spot and brazing that in. Would that be strong enough or is the frame dead? Its not worth replacing the whole seat tube I think. It might look a little funny but that's ok. Obviously afterward I'll run a super long seatpost to add strength to the spot.
Many thanks for your help!
Cheers,
Dylan
