Compatibilty of Components with Older Frame(6 posts)

Compatibilty of Components with Older Frameredsub

I am buying an older Toreeli frame from late 80s to early 90s. Will I have compatibilty trouble with putting new forks, headset, etc. on the bike? This is the first time I was going to build a bike up.
Shouldn't be a problemretro

You'll need a threaded headset, 1-inch fork (you could find a 1-inch threadless w/fork, but there's no real advantage either way) and quill stem, but they're readily available. My Atlantis uses the same stuff, and I just built it a few months ago.

You may need to spread and align the rear dropouts for the wider hubs if you go with an 8 or 9 speed drivetrain. BB will probably be Italian threading so you need to facotr this in when looking at drivetrain choices. Make sure you measure the seatpost tube diameter. Headset will depend on fork selection, but shouldn't be a problem. Verify that the frame is designed around 700C wheels and NOT 27" otherwise you'll have a hell of a time finding decent wheels and brake reach will be an issue.

Odds are good that you won't have too many problems if the bike is from the 90's, but if it's from the early 80-'s anything goes.

Not that you want to hear this, but it ususally isn't worth building up older frames with new parts. It's the most expensive way to go, you have comatibility problems and when you're all done you have some nice light parts hanging on a dated and heavy frame. However, some folks are really into the retro thing so to each his/her own. The cheapest way to buy parts is on a new bike.

Here are more details: White, 50cm Torelli frame, with Shimano 600 headset, 105 braze-on front derailleur and bottom bracket. Does this give any hint that I won't have problems with parts?

I never have problems with white bikes. ;-b

What you're asking and the information you're providing doesn't really give that much info since you haven't nailed down the year of production and how the bike was originally configured. An experinced mechanic could give some good advice if you brought the frame in from them to look at.

You're probably OK, but you may still need to spread the rear dropouts. You may not even know if the frame is straight. Ask yourself what is so special about this bike? You haven't really had the full bike building experience until you try to set an old bike up with new parts.

I'm assuming that your BB is of the square taper design and NOT a spline type. So now you either need a matching crank or a new BB to match the new crank. Then you want to get the chainline correct - which may or may not be an easy thing. Whatever you do make sure you plan out the major components in advance. Once you bolt stuff together and find that there is a problem with something you will have a hard time returning it for full credit.

The biggest issue you may have is the rear spacing. 1990ish is when the spacing went from 126mm to 130mm to accomodate 8 cogs. Standard for road bikes remains 130, so if the frame is 130 you can put 9/10 cog drivetrains on it. but if it is 126 you are stuck finding old 7 speed parts: good luck!. Or, you can have the rear triangle spread out to 130 by a frame builder. Be nice to know what you are dealing with before you lay down your cash.
