    1992 Viner Frame Questions

    I just purchased a NOS 1992 Viner steel frame. Call it irrational affection about Italian Steel Frames.

    I haven't recieved it yet and am attempting to create a plan to aquire necessary parts to move components from a Trek 1500 to the Viner.

    I have another bike to ride and want to build up the Viner myself. From the questions it will be obvious that I am not a bike mechanic but I doing maintance on the bikes I have now.

    Some questions:

    Does this frame use a down pull FD?

    Will I need to purchase a different FD to use with the braze on FD tab?

    It has adustment screws in the rear droputs? I assume these are from micro-adjusting the chain tension. Why?

    The bosses on the front tubes look like they are for friction shifters. I am going to use STIs group set from another bike. Anything I should know about buying a conversion kit so that I can install bosses on the down tubes for the shift cables?

    There appears to be a bulge or ring (see photo) around the steerer tube about 1" above the headset. Anyone know what this might be?

    Thanks for the help.

    I, too, have recently acquired a '90's lugged steel Italian frame and fork, mine is a '96 Pinarello. I've got the hots for Italian steel, what can I say? Congratulations on the Viner, that should be a wonderful bike.

    I'm putting a modern Campy group on mine, I gotta go all Italian on this one.

    The frame will use a braze-on front derailleur, which will be bottom pull. The bottom bracket shell will be Italian threaded, 70mm wide (saw your question in C and V). The adjustment screws in the dropouts are primarily for micro-adjusting wheel alignment, and everything will work best if you set it up so that the axle is towards the forward end of the dropouts. For the downtube braze-ons, you will put cable stops/barrel adjusters there, this will work fine with the STI shifters-

    Hope this helps, and enjoy that nice frame and fork-

    Some questions: ???????????????

    Does this frame use a down pull FD? <-- yes

    Will I need to purchase a different FD to use with the braze on FD tab? <--- If you dont have one that fits the tab aka a fd with clamp.. yes u'll to purchase one w/o a clamp.

    It has adustment screws in the rear droputs? I assume these are from micro-adjusting the chain tension. Why? ??? <----- No clue, maye be it has (usually some brands dont have them in their short drop out models, other brands have them), no that's not for adjusting the CHAIN TENSION, those are for adjusting the wheel at the center of the frame!

    The bosses on the front tubes look like they are for friction shifters. I am going to use STIs group set from another bike. Anything I should know about buying a conversion kit so that I can install bosses on the down tubes for the shift cables? <--- Im not familiar with shimaNO STI but Campagnolo brifters have the adapters to put in the down tube bosses right in the box.

    There appears to be a bulge or ring (see photo) around the steerer tube about 1" above the headset. Anyone know what this might be? <--- im not that sure if that fork is threaded or not, but looks like is not threaded. What u see can be sort of sleeve they put in the fork to keep it in place. Dont worry about it.

    Have Fun

    Campy Dreaming

    I wish I could go Campy on this bike to keep it with Italian tradition. I just can't afford it right now. I have an entire Shimano group set on the Trek 1500 with only a couple of hundred miles on it. I purchased the 1500 for my daughter, in an unsuccessful attempt to get her into cycling.

    Thanks for the very helpful reply. Fun safe rides on your Pinarello! Sweet bike.

    Thanks for the reply. Very helpful.

    One follow-up question re: those are for adjusting the wheel at the center of the frame! <---Why would would one need to adjust the wheel at the center of the frame?

    Thanks again for the help.

    Well... thats an old frame, back in the day u were able to fit any rear wheel in there (untill brifters came out), and as makes sense not all the hubs are equal, someimtes wheels were more dished to the left or to the right, thats why u needed to center the wheel by hand or use those little thingys to keep them centered all the time, to adjust the wheel in the center of the chain stays (not in the brake bridge area).

    Now a days with carbon bikes and shimaNO or campy setups is not needed anymore (persay). All the shimano wheels will be dished equal eventhought have different brands, with campy is the same thing.

    Just in case shimano and campy dishing have a little difference between them.

    HAve fun with your built

    The dropout adjustment screws aren't really necessary, but they give you a guide for aligning the wheel in the frame and positioning the axle in the dropout. With horizontal dropouts, once you put a wheel in there, I think it will be obvious what they're for.
