Rescuing a Pace RC200 F4 Frame
- Thread starter Papillon
- Start date
Hello all..!!
im new to retrobike and must say wHAT a brilliant thread. Its even more interesting as i find myself in the same dilemma as papillion did, i have a RC200 F5 fame that has a stress fracture/crack near the BB.
I have been in contact with a company that do Tig and laser welding who say the can sort out the issue. Now the dilemma is that after seeing this awesome thread im in two minds.??
If i get it repaired by just welding the crack then im sure over (short) time it will fail again? and im back to square 1, but if i get the whole seat tube replaced for a more stronger one then this should in theory be the best route for longevity?
I was hoping that Dan could reproduce his magic on my poorly frame?
any thoughts on what i should do?

Re:
Excellent thread this one.
So, Dan - would you shy away from repairing a Manitou HT…?
Would need a new head tube, but whats that when you're replacing seat tubes etc on Pace frames…?!
Let me know, I have a good candidate for surgery.
Back to the Pace!

Re:
Certainly no problem actually replacing headtube. Cut out and fit a new one like I did with the seat tube.
Problems arrive with the real need to post-weld heat treat and the consequent risk of over-treating the existing frame welds. Otherwise, might need to anneal the whole thing post-weld and start again.
The jury seems to be our on whether it's necessary for 7005 repairs, but it is pretty much a requirement for anything 6061.
All the best,
