Another to always have had great service from SJS, indispensable for all those little bits and bobs!
A Thorn frame came my way recently and I was intriugued and puzzled by it from a framebuilding perspective, all the tubes were sealed, no breather holes. Even the bottle bosses were blind ended inserts.
Needless to say it was full of water and the tubes had rusted from the inside out.
Drilling a drain hole in the bb shell and whether or not to seal up breather holes are topics often discussed but never seemingly resolved on internet cycling forums, this was the first time I'd actually had a sealed up frame in hand and it gave me all the answers I need!
