    Fancy tires on cruiser......

    Hey all,

    I don't know much about bikes so I've come to ask questions. I just bought a Bobbin Birdie in Pale Yellow and I'd really like to put these Aerospoke wheels on it in a fancy colour but I'm not sure if they're compatible. My questions:

    If only the front wheel is compatible, would I get the 700c Front, the 26" Mountain Front, or the 26" Tandem Front? I don't really want a quick release wheel for the front so I'd ideally like to get something that I can bolt on.
    As the Bobbin I got has a 3 speed Strumney-Archer internal hub, I assume the rear wheels are incompatible. Am I correct in this assumption? If not, what back wheel would I get?

    thanks,

    valley girl

    First off, realize this: they're all gonna laff at you!

    Now that we've got that out of the way, here's some thoughts/facts on it:
    -the Bobbin takes 590 wheels; 590s with the standard 38mm rubber are the same diameter 622 wheels with 23mm rubber, or within 4mm. So, yes, they'll fit inside the frame. However, the fenders will at the very least a l'il chunky, wrapped around skinnier tires. Theoretically, the fenders may rub the tires at their highest point, but tbh I'd be surprised if that were the case. More problematic would be brake reach; you'd need to change the calipers and, depending on what reach the stock brakes provide, and where the pads sit in stock form, it may be very hard (near impossible) to set up the brakes correctly.
    -as far as hub spacing goes, the front will be no problem. The Birdie comes with a S-A 3 speed "freewheel" (ie, no breaks), which will be spaced between 116mm and 130mm; 120 seems most likely, but any of these are possible. So,you could run an aerospoke with the "track" rear hub, but you may need to spread the frame by 4mm (easily done) or put some spacers on the axle (also easy). Once you get the Birdie, measure the space between the rear dropouts to see what (if anything) you'd have to do. Obviously, if you go this route, your bike will become SS. If you wish to retain the 3speed gearing, you'll need to only change the front wheel.

    Whatever you decide to do, be prepared to explain to ppl why you're putting a $800 track wheelset on a $600 40-pound townie bike. I'm not judging you; I ride a Worksman with a Chris King headset, so I am not fit to judge. I'm just trying to keep you prepared.

    You can say that, but i think it would look good on the front if it was a 559 aerospoke. If it looks good, who cares, I want a set of Deep V's on mine. It has a Kenda Kwest on the front and a Kenda 838 on the rear and is built for speed- needs freewheel and bmx 3piece.
    The speed is break neck, faster than a high speed dual cassette tape deck.

    a 559 up front would bring the front end of the bike down considerably, unless she runs a fat tire, in which case she'd likely run into clearance issues and fender issues. Plus, she'd have to go brakeless unless she swapped the fork for something with disc mounts. Of course, now we need a new fork, the disc caliper, likely a new lever unless she goes with a "road" disc caliper, plus the disc aerospokes cost more... At least the 700c version can run with the existing fork and levers, and won't effect the geo noticeably...

    Regardless, the fate of this project seems murky...
