I have a Tange Infinity frame that I coldset back in 2001 because I wanted to put Veloce 9-speed groupset on it. I realigned the dropouts at the same time. It's still riding fine.

I have a Tange 5 frame that I had converted to a touring bike also with 9-cogs in the rear. Before I coldset that frame I was riding it with the 130mm hub forced into the 126mm dropouts. That stopped after flatting one very hot day. The wheel came out without too much problem, the new tube was put inand the tire pumped up. Then came the fun part of trying to get that wheel back into the dropouts. Fortunately at that time the bike had aero brake levers on it and thus I was able to turn the bike over. I ended up having to lean on the wheel with my upper body and push hard whilst trying to spread the frame enough fopr the wheel to go in. It finally did. I'll never squeeze a 130mm wheel into 126mm dropouts without coldsetiting the frame first.

Cheers
