Time to get to work on that head tube brah

Hahaha, Seems sketch, is that safe to do? I think if worse comes to worse, I could take a 22.2mm stem to a machine shop to have them machine it down to 21.1mm

filing the headtube won't help, it's the steerer that matters. I'd sooner sand down a stem. You don't really need to take it to a shop, just get some sandpaper and go to work.

Harris has a few in stock, although it may not have the rise you want:

Please stop giving bad advice in my thread. ;)

She put function first but I definitely agree. It's a really great looking bike. More pics and full specs here.

Will red velocity velo plugs fit a23 rims?

Sure.

Back in the days when people still used nutted calipers, Cinelli used to make a brass shouldered washer for exactly that purpose:

They shipped them with their brake bridges but I don't know if they're still available separately.

Yeah that's what I'm going to do. My buddy found a 80mm extension stem at the local swap meet for $5. Sandpaper it is. Looks like it's a forged Aluminum stem too so I can actually polish it without much work :D

Derp - forgot an important point:
American bikes used thick tubing in small diameters (and often Ashtabula's thick, heavy forks,) while European and Japanese bikes used thin tubing in large diameters. Over time everyone has mostly shifted over to European-style tubing, which is why a BMX 7/8" (thin tube*, thin steer tube) and a Schwinn 1" (thick headset tube, thick steer tube) use the same stem. However, a 1" BMX headset will probably fit your bike.

*or extremely thick tube with the same inner diameter for making "sweet jumps"

More confusion: Schwinn used European parts on their high-end bikes, and by the 70s they were selling Japanese-built bikes as their own. If you go the eBay route, be aware that a Schwinn quill may or may not be the right size for your bike.

While some think "ABS" means a part was made by Ashtabula, it really means "anti-lock brake system." If you want to do some sw33t skidz, you should remove those parts immediately and throw them in the trash. Especially Stingray forks. ;)

You're still giving bad advice. He's not looking for a headset, he's looking for a shorter stem - and unless he gets a new headset and fork, he'll still need a 21.1 quill.

Double derp. I meant to say 7/8" BMX and 1" Schwinn use the same -quill- size (21.1,) so he may be able to find something compatible. Unless you know something I don't.

Scrod, so I picked up my fathers Cannondale mountain bike, and it's in pretty bomb condition. Decided to not fix what's not broken. Only problem is (other than reflectors galore) the bike comes with OnGuard locking skewers on the rear and front wheels and the seat post clamp. And of course, there's no KEY! What do you think I should do? Do you think some pliers would be able to get it off? Pretty sure this is it: http://www.amazon.com/OnGuard-3-Piec.../dp/B000C14NEG

Nice score calv!

homebrewk 11-13-11 07:25 PM

Scrod,

How long does it take for my bike to show up on myfixedgear.net?

Usually about a week.

Dude, I have no idea. I've never had to mess with those things.

homebrewk 11-13-11 09:02 PM

Wow. Ok.

Sherblock 11-13-11 09:40 PM

Scrod, why is your shop listed on the page of people who support them without a link to your site? Get on that.

Man, that sucks. Hope I don't get a flat or something. At least the seatpost height is pretty accurate.

jimmytango 11-13-11 10:18 PM

You could try to drill them out, tap them, and thread a bolt with Loctite or JB Weld into each one and use that to back them out. Downside of course is that if you mess up, you'll probably need new axles.

Jaytron 11-14-11 12:27 AM

Scrod,

What's your take on Schwalbe Durano vs Gatorskins vs (insert good daily tire here)? Looking for good long life and good puncture resistance. I've been here pretty good things regarding the Duranos.

BoozyMcliverRot 11-14-11 01:18 AM

Im not Scrod,but I use Specialized All Condition tires,They work and are cheap.These tires dont have the best ride,but Im 4 years in and they still have usable tread and no flats yet.

EpicSchwinn 11-14-11 01:21 AM

Four years and not a single flat? How much do you ride them??
