Cleaned all the grit etc and regreased and took for a ride seems to be alright. the only question is how tight do you tighten the left crank?
Even though I'm fairly new to serious DIY bike maintenance and mechanics - has there been something of the value lost in recent years about having a drainage hole cut/machined/drilled into the lower most point of a frames BB shell?
The couple of new Surly frames I have had personally in the last 3 years have neither come with such a drainage hole. I rode my brand new Steamroller for about 2 weeks before I tore it down for a project. I got caught out in ONE (1) shower riding home in that time - and I couldn't get over how much liquid came out of the shell when I unscrewed out the BB.
I've had the small modification of a 5-8mm hole drilled in the lowest BB shell point suggested to me from a local frame builder and I've since done it on both of my Surlies. I also have seen such holes or fancy pants cutout shapes in a lot of the better quality steel frames I've seen online. My kerbside find Cro-Mo 80s MBK came with one.
Do any/many of the mass production manufacturers make this small mod to their frames these days? Surely whether the frame is CroMo, Al, Carbon Fibre, Ti, Polystyrene, Unobtainium or whatever - such a small mod would save moisture gathering around steel BB bearings??
