    Dont forget 507mm for 24" kid MTB's, 571mm for 650c (26" narrow road tires) both are fairly common. There are also a couple of other 20" wheel sizes that all use different rims. I

    Fat bikes use standard 559mm (26" mtb tire size) rims that are really wide (65-100mm width) combined with a huge tire to achieve tire outside diameter that is very close to a 29'er mtb tire. While...

    Easy solution, there are these offset brake pad holders that add 7mm of reach;

  4. Rebuilding the wheel with quality new spokes...

    Rebuilding the wheel with quality new spokes should be a good fix and work fine so long as the rim is not bent. No compelling reason to replace the hub if it is still in good shape but check first...

    Late in his pro career, Alexi Grewal suffered a serious back injury from an automobile wreck (rolled his jeep off the road). Persistent back pain from the injury made it too uncomfortable to ride...

    Looks very similar to the Banesto team bikes that Indurain rode to TDF wins. Presence of interior helical splines in seattube would indicate if it was SLX or TSX, oria also used splines that run...

    If no spacer between the cartridges, I would adjust them just slightly looser that typical for a loose ball and cone bearing. You will kill the cartridges if there is side preload through the...

    If you find that 8s shifters and 7s FW dont play nice together, try one of the alternate RD cable attachment locations in order slightly alter the pull ratio of the RD to increase travel of the RD...

    Between the mix of campy/sach/gipiemmi components that are on there now, it is highly likely that someone changed out some of the parts at one time. THe sachs components were somewhat of a budget...

    It would probably work better if you disassemble the freewheel and use callipers to measure all the existing cogs and spacers, then use sandpaper to lap the spacers thinner where needed in order to...

    Ranf should be one of the nicer Oria tubesets, it has vertical (not helical like columbus) reinforcing ridges inside the chain stays, down tube, steer tube and seat tube (in which the ridges run...

    I would estimate that this blue QA is from around 1990, give or take a couple of years. Looks like conventional size tubing and classic campy dropouts. Steel QA's from the early/mid 90s were built...

    I have a modolo 1" quill stem that dates from early 90s that used a hinged bar clamp to allow for easy bar mounting. It is not completely removable faceplate design like the more modern & common...

    Post some good pictures for an ID of the bike, including any tubing decal. In the 2008 example post above, the decals looks consistent with the QA EL-OS road bike I bought new directly from William...

    You might try using cantilevers fitted with these offset brake pad holders;
    BDop OFFSET HOLDERS

    These are road style pad holders so wouldnt work for post mount pads but there are cantilevers...

    If there is not an external friction shifting setting, you might be able to just open them up and gut the index mechanism. I seem to remember that suntour index shifters used small ball-bearings and...

    There were long cage Chorus and CDA long cage rear derailleurs made prior to 1992 arrival of ergo shifting that were intended to work with synchroII shifters and had capacity for a 30T rear cog. I...

    I would guess that the bike dates from 1930-1940's. Are the rims wooden or steel?

    Looks to me like the crank has self-extractor bolts, a feature not found on Athena. More likely these are CDA or Chorus.

    I really like the look and font of the downtube decal. Paint on this bike is in fantastic shape for its age. Interesting that it still has toeclip pedals, non-aero brake cables and friction shifting....

    Replacing the cable guide is a very easy brazing task, very do-able. The bike probably got used as an indoor windtrainer at some point with dripping sweat producing rust. Cable guide replacement...

    92mm is a lot of trail for a road bike, that would require either an unusually slack HTA and/or a fork with very little rake. I really dont think such a bike would have any redeeming handling...
