    A 410 Trek and Raleigh Triumph: Looking for advice

    Hi everyone,
    I have a bunch of questions I wanted to ask to the experienced bike community. I am a newbie so most of my knowledge when it comes to road bikes and bicycles in general comes from reading a few webpages in the last couple of days. (sheldonbrown, vintage-trek and so on).
    I have recently come into possesion of two road bikes:
    1) A 1985 410 trek. Checked the serial and it should be the 410 described here: http://www.vintage-trek.com/images/trek/85TrekSport.pdf
    2) A Raleigh Triumph with serial number beginning with 7B94G. I am guessing this is from 1979 but I am not sure as it doesn't really fit in the dating scheme described here:
    http://retroraleighs.com/dating.html#kent

    The trek is 21" frame (12 speed) and the Raleigh about 25" (10 speed) and I am 5'10" so please keep this in mind.

    The trek is in decent shape except the wheels and tires (chain a bit rusty too). The from wheel wobbles a lot to the point of hitting against the brakes and it seems to have a protrusion around that area. This one looks really bad so I am thinking about replacing it. The rear wheel seems Ok for the most part but when I flip the bike over and spin it fast, I notice a kick or hop (or whatever it's called) in the vertical direction. I am not sure this can be fixed by trueing the wheel but I guess this is part of why I am posting here. The tires seem in bad shape but here is my first question:
    The wheels are 27x1-1/4" but the tires are listed in the brochure I list above as 27x1-1/8" and I have looked at a bunch of online stores and it doesn't seem like 27x1-1/8" tires are around. I can find 27x1-1/4" tires just about everywhere so what is generally recommended in this case? I have also looked at wheels and I am not sure what type of brand to go with. I don't want to spend too much but I also want to get a decent wheel. Any suggestions? (obviously I have looked at bikepartsusa, nashbar, wheelworld)
    What about tire brands? Kevlar or would just regular tires do. Would like to go on ride 10-20 miles on bike paths but not really for daily commute (not right now at least).

    The Raleigh is rideable as it is; I had to buy a couple of wheel nuts but that's about it. It is 25" frame (c-t) and I have the seat adjusted way down for obvious reasons. The frame is is very good shape, looks like original paint and original components (so does the trek by the way). It can use a new set of tires as the old ones look cracked at some places. I really like the ride on this one, it feels very comfortable. It could also use a new owner; one at a minimum 6'1" or taller but I will keep this while I fix the trek.
    It seems like I have made up my mind about fixing the trek and possibly trading or selling the Raleigh eventually but I am willing to entertain just about all kinds of suggestions. All advice is appreciated. Thanks

    You need a frame size in between those, but to choose - keep the smaller and sell the 25". It's too big and you'd hate to come down on the TT with your boys.

    And maybe swap the wheels if they're compatible. Jettison the Raleigh.

    No,
    the wheels are not compatible. I like the way the Raleigh rides; it's just too big. I would keep it otherwise. Not sure what to do about the tire size of the trek.

    What makes you say the wheels are not compatible? Most road bikes of that age used 27" wheels. If its the width over the lock-nuts because one is five speed and one is 6 speed you can just push the drop-outs out a little as you install the wheel, or if you want to, you could cold set the stays.
    As for the tire sizes, you can use a 27*1/4. It's only 1/8" different in width and all rims can take a range of tire widths.

    I also have a mid-80s Trek 410 and have used 700C wheels on it without problems, so that is an option if you want. The Dia-Compe brakes have no problem reaching the slightly smaller rims.

    Ok, I didn't know you could do that. Both bikes use 27" tires although the ones on Raleigh are wider. Obviously, there is the difference in number of rear sprockets. And I don't know what you mean by cold setting the stays. I think, at this point I would like to get two new wheels on the trek. And I'll go with the 27x1-1/4" tires and what should the tube size be for that wheel? The same?

    Ignore my last question. I measured the rear hub spacing and it looks about 126mm. The brochure lists the original hubs as Atom std. Silver Q/R alloy (does standard mean 126 mm?). Also, is silver alloy lighter than chrome steel? I am not sure which way to go there. Original was silver by the way.

    I'll let Sheldon Brown explain cold setting.
    http://sheldonbrown.com/gloss_cn-z.html#coldset
    As to what rear drop-out width is "standard", that depends on what was being sold for groupsets when the frame was built. 126mm was "standard" when 6 or 7 speed was "in". Now days its 130mm for 8, 9 and 10 speed rears.
    Get a tube with a width range that covers the width of your tire.
