    OK, Sorry, I get a little huffy when I think I am wasting my time....

    If that is a picture of the bikes actual BB, it doesn't say a whole lot. I have seen that BB on Miyata's, Specialized's, Univega's and a couple of others. It is a pretty standard piece.

    It DOES NOT mean it is a low quality frame, nor does it point to a good one either. My Miyata 1000 has that BB and it is a top notch frame, as does the Specialized Expedition, also a top notch frame. On the other side the Univega specialissima use it as well, and it is more of a standard frame, still pretty good though. None of these frames used 531.

    Sorry if that is vague.

    I will look at it some more and see if anything catches my eye.

    Jack Taylor also used a similar BB, they thinned (filed the edges) them out though. They used 531.

    Thanks for that information. I guess my comments re lower grade tubing may have been swayed by the grotty paint job, lower quality cycle components and overall condition? If I can find out whether the frame has some decent pedigree re main tubes, then perhaps I'll be more motivated to give it a decent respray/rebirth. Here are some more shots:

    Perhaps another option is to carefully strip the paint off and hope that the old stickers/transfers are still there? I gather the seatpost diameter would also help clarify. I have a vernier caliper somewhere.

    OK, So the overall thickness of the lugs points to stamped lugs instead of cast which points to a lower quality frame. as does the style of termination from the fork leg to the dropout. Steel seatpost is another (may have been added later). The seatpost lug is also a sign, it is hollow around the clamp bolt instead of solid, this also points to a stamped lug instead of cast.

    Pressed (stamped) lugs are not necessarily a sign of a "bad" frame, it is the lack of finishing that is the big pointer. The lug thickness is constant, if a frame is a quality frame the lugs would have a filed taper as the get closer to the tube. The edges would also be softer yet more sharp as well...

    There are other things that are covered by the paint that would tell. The "shoreline" for one, it is the junction between the tube and the lug. If it is sharp, it is of good quality. not so sharp, lesser quality....

    It is still a lugged steel frame.

    Hope this helps, sorry it is not more exciting.

    My new Edge 500 came in today. So far, I like the computer, but Garmin Connect is being a PITA.

    Ride tonite took longer than normal 'cause there were 3 flats. None of em mine. :nah We only went the short route. :baldy I wanted to go round the whole loop, but...

    So we set out at what felt like arctic temps but were really normal for this time of year. Dressed for normal for this time of year. Soon as we got up the first hill, it got warmer. Got colder again down the hill, then REALLY warm at the top of the 2nd hill. :confused Completely back-asswards from the way it normally goes. Reminded me of riding in Sandy Eggo with the thermocline and all.

    Only 3 of us tonite. WE had fun. :nod IDK about all the rest that are *supposed* to show.

    It is a legitimate inquiry.

    I wanted to yell "STRAVA!!!!!!!" while running a red light on my solo 30 mile midnight ride tonight but there was no one there to appreciate it. :lol3

    The boot camp I did with my friend last week really took it out of legs and I struggled the entire time. I think she owes me a massage...

    Very interesting comments - thanks for taking the time. I had no idea that lugs could be fabricated by stamping. How are the stamped halves joined? I was pre-judging the chances of 531 tubes by the low quality fitted cycle components together with the wall thickness of the seat lug clamping the seat post - it looks quite heavyweight compared to another 531db frame I had made in the 70s. I think I will be stripping the paint off in due course and will be on the lookout for any decals/transfers buried within to clarify. Seat post and external seat tube diameters will then be recorded. But based on your own analysis, mud, I'll expect little of quality.

    :evil I realise now that these photos should have had a NSFW warning in this thread! Retrospective apologies to those of a sensitive disposition where CF, titanium, hard anodising and other aerospace centred technologies are the norm. Here's a closing image to normalise affected folks!

    You know what? If the bike "floats your boat", fix it up. Below was a project that one shop owner actually laughed in my face. No worries, I found a shop who was as enthusiastic as I.

    1963 BSA Sports....maybe a $200 bike, in mint condition.

    Cheers! Its the 25" ctt frame that is the appeal. Sure its ugly but the extra steel on the frame is probably only an extra pound or so over a one with a good pedigree. I've got 3-4 other source bikes and am going to scour them for various bits to just run it around town. A shimano 3 speed hub on a 27" rim is looking good. The ratty look has a certain appeal to it.

    My big question becomes 'why let your opponents know how fast (or how slow) you're going?!

    I'll stick with another software package that let's me keep that private, thanks.

    ...and I'm not fixin to brag about 'winning the training ride' any time soon. :nono

    Maybe you should use it to your advantage by uploading slower runs than you're actually capable of. :deal
