TIG welded Columbus Zona versus lugged Columbus butted (?SPX?)
I am suddenly without a rideable bike (Mikado / ProCycle POS frame
broke, they don't respond to Emails, they don't have a listed phone or fax number) A local dealer has in stock a 4 year old unused Marinoni Turismo - lugged Columbus tubes, threaded headset versus the new model with TIG welded Coumbus Zona (non-round) and threadless headset. Intuitively a lugged frame can be repaired, but that assumes availability of suitable tubing. Quill stem seems to offer easier minor adjustments to height, without worrying about tensioning the headset (perhaps I misunderstand how threadless works ?). Again, quill stems are harder to find. Since there's no discount on the older frame, I'd be inclined to buy the later version EXCEPT that there's an 8 week wait. This is NOT an inexpensive frame. Any comments ? |

Incidentally, if I remember correctly, the price quoted at the time for a 56/57 cm Turismo with headset and stem was in the neighborhood of $750 Cdn. Luke |

I can't believe the shop has a 4 year-old frame that they won't discount 15
% or so. Perhaps you can push them a bit harder. Tell them that you'll take the newer model and let them keep the other frame for another 4 years unless they can provide you with a good reason not to. If you haven't been talking directly to the owner, then make sure you do because underlings don't usually have the authority. Blake "mark freedman" wrote in message om...

TIG welded Columbus Zona versus lugged Columbus butted (?SPX?)
I have a lugged Columbus Brain from Marinoni too. Brain was never top of the
line in terms of racing tubesets, but it's probably ideal for anyone who isn't racing with it, due to the more perfect balance of weight vs strength. This is because it really just classic Columbus SL, the equivalent of Reynolds 531 (except it has a more advanced butting pattern). For the classic quality steel frame ride, it's hard to beat. It's not bottom of the line either, as there were at least two lower Columbus tubesets in the hierarchy. Marinoni has switched its production to TIG welding, mainly aluminum, but some Columbus steel. However, I believe they still produce custom lugged, round tube steel frames for those who want them (the cognoscenti among us Marinoni used Brain tubing for it's lighter sports touring bikes (Ciclo). The Turismo had the heavier and stronger SPX. This all sounds like ancient history already, but this was just a few years ago (not even five years). Why people go for the cheaper methods of building frames now is beyond my understanding, but I guess Marinoni had to stay competitive with all the other lemmings. Personally, I would think a lugged Turismo is far more desirable than a TIG-welded one. Pierre "Luke" wrote in message ...

The different grades of tubing will vary in hardness, ductility, fracture toughness, fatigue resistance, and tensile strength, but WILL NOT significantly vary in elastic modulus (true of all steels). Therefore, any differences in ride (assuming the same frame geometry) will be due to differences in tube diameters and/or wall thickness. Tom Sherman - Quad Cities USA (Illinois side) |
