    BB and crankset (and what first) for Raleigh Tamarack ?

    Couple days and I brought tenth bicycle into my garage-blue Raleigh Mountain Tour Tamarack.

    What caught my attention (and I love it) is that weird but beautiful handlebar.

    No BB, no crankset on it. I measured BB shell, it is 68mm. But there are many different 68mm BBs...anybody knows how long spindle should I buy ?
    Or should I "find" crankset first and than buy suitable BB ?

    Front wheel took me hours of elbow grease but result if very good. Rear wheel (rim and hub) are really rusty, I will try oxalic acid etc but I doubt it can be saved, may need to build new wheel.

    As you haven't bought anything yet, it give more options, unless you are looking to keep the bike vintage, would look at an external BB (HT2) crank, no need to think about spindle length, as it's fixed, for budget, would be looking at something like Shimano Alivio (M4000 series).

    If sticking with square taper, would find the crank first, then work out the BB spindle length required.

    Figure out what crankset to buy and then get a BB to suit; it is often cheaper to buy them as a set.

    If the rims are steel, which would seem to be the case since they are rusted, I would recommend replacing them if you can swing it. Steel rims REALLY SUCK at wet braking, to the point where I consider them dangerous. If the hubs are also rusted I would carefully scrutinize the bearing surfaces; if they are rusted they are not worth wasting time on. You can get new balls and cones but the races in the hubs are not replaceable.

    I am not sure but it seems that front rim is alu-cleaned and polished very well, there was no any rust on it at all. Front hub is definitely alu and looks very well. Rear rim is very rusty, hub a bit rusty also.
    Wheels are 650B-impossible (?) to buy for a reasonable $...perhaps will get some guru to build a new rear wheel for me.
    Will do as you say with crankset-BB (crankset first).
