| My schwinn is still in top shape but i moved to the mountians. this bike is geared for flat land. it has Sugino MP110 crank set. 52 and 40 teeth gears. looks like it has mount for a third sproket like 22 teeth. Does anyone know if i can add a third smaller front sproket?|
Shimano SIS shifters and derailers.
| I've done it. Front derailleur takes some finagling, to go in that far. Read Sheldon's remarks on chainline. And if you run into complications, take a Sugino triple, 46-36-26 for example, and try that.|
| I put a Dura-Ace on my Trek 500, and ran a 53/39/26 for the mountains (11-28 in back). I was able to take it up SnowBowl road in Flagstaff. 7 miles of up hill with a 2000 foot gain. Not all derailleurs will handle big tooth differences.|
| Thanks Ken I reall still like this bike and did not want to get rid of it. If i can modify it so i can ride it in the mountians of south east tennessee that would be great.|
| Hey Ken, Can you tell me what issues you ran into when adding the third chain ring to the sugino crank set. I just got a 26 but i then found that the mounting holes have no threds. It looks like i will have to tap them out and add a spacer to mount it with the proper spacing between inner and middle chain rings.|
| i believe the bike i just picked up is a bottecchia by carnielli. early 70's? i think it is a "special" model. there is a "S" on the seat clamp. pump mounts under toptube. campagnolo grandsport crankset and pedals, valentino extra deraiuller. universal center pull brakes. any thoughts? or comments? thanks!! |
| Bottechia's crap.|
| Not all crap...just most of the ones marketed in North America.|
| Billy, Billy, Billy... let's try to keep it positive. Describe your Bottechia experience in detail, so we can judge whether you were JRA...|
| boneshaker or bonehead?|
| Have a look at the Bottecchias on this page...http://www.teamkarim.com/bikes/used/road/road.html|
Not so bad...eh?
|Not sure where the vitriol against Bottecchia comes from. Bottecchia, unlike some other Italian cycle manufacturers, was a full spectrum manufacturer. That is, they made everything from kids bikes, city bikes and utility bikes to professional grade racing bikes (and yes I am aware that some of their star riders were riding custom made frames rather than factory Bottecchias but that was not/is not uncommon at that level of racing). The Special is considered by some today to be a bottom of the line bike but in its day it was really more of a mid-range machine. Considering that a department store bike of the early 70's cost around $85 and an entry level Peugeot around $125, the $175 Bottecchia Special with its aluminum bar and stem and (usually) Campagnolo Valentino derailleurs and (sometimes) Campagnolo Tipo hubs was a cut above. Of course it had a straight gauge hi-tensile steel frame but double-butted cromoly was not used in those days until you got to much higher grade bikes. The Gran Sport cranset is unusual. It may have been an aftermarket upgrade as I am not aware of any Specials coming with that. As for value, not much I'm afraid. $100 - $150 is about it. Let me know if you would like more information about the Special model or Bottecchias in general.|
| I recently came upon a 5 speed freewheel. The only markings on it are G Momme's or G Monm'e or something similar. Can any one out there enlighten me as to country of origin and Mfg.|
| Gipiemme, perhaps?|
| Could be J Moyne in script. 60's/70's. French freewheel. The earliest are from the 30's. |
| is there anyway to tell who manufactured a bicycle just from the serial number? |
| It's possible some mfr used such a distinctive number AND someone remembers what it means... but I'm very skeptical.|
| I've had my best like identifying bikes by scrolling through the picture database.|
| i have a columbia two seater and i am not sure how much its worth or what year it is|
| There is a tandem page on this site.|
