Once the fixed cup bearings are in, put the spindle in. Install it with the longer side(drive side) going down into the fixed cup. Hold the spindle in place and stand the bike up again. Hold the spindle from the drive side. Take the adjustable cup with bearings and slide over the spindle. Screw in the adjustable cup. Righty tighty. MAKE SURE YOU DO NOT CROSS THREAD THE CUP. There should be no resistance. DO NOT FORCE THE CUP. If there is resistance, back out and check the threads. Screw it in by hand as far as you can. Then put the spanner on. Keep turning until you feel some resistance. Put the lock ring on and hand tighten. Once you feel some resistance, check the spindle. There should be no play. Now slip the crankarm on. Spin it to see that it spins freely. You're looking for the point that is not loose, but not dragging either. When you find it, take crank arm off. Hold the spanner with one hand and fully tighten the lock ring with the other. Put the crank arm back on and check for the magic place again. Adjust if necessary.

Reinstall your crank/arms and you are done! That was time consuming. I believe I will do the headset in the morning. Questions or comments? Please list them so we can go over them.

I think the reason mine end up like that is that I am holding the nut wrench in line with the spider arm during tightening.

Tribiker, those Conti's are 700c not 27 inch, so they won't fit. Too bad.

Pasala Panaracers come in 27", or they used to.

Edit: I just noticed there is a 27" thread in the stickies at the top of the page.

To clean , you could just use soap and water with a stiff brush not to abrasive go lightly . To polish , you need to know if they are anodized . To find that out get some paste polish and test a spot , if not anodized the rag will turn black and you can polish . If the rag does not turn black , they are anodized so all you can do is scrub . Those ferrules look in very good shape so worth cleaning up either way . Good luck . Mark .

Finally, I'm gonna ride tomorrow. Probably 20 miles. The last time I rode I was on my Miami Vice. It was a fantastic ride. To be clear, I'm not saying it was the bike that made it great although I know the Ironman bike wouldn't stop me from having a great ride. I was just having a good day. But on that point, it's Nice to know that when you're on an Ironman, you Can't blame it on the bike if you have a bad ride.
I think I'll ride my Carbon "midnight rider" Ironman tomorrow.
Shout out to markwesti . Glad you made BAIL and welcome back 😁.
Later Ironkids.

Use a plastic knife or something and grease up the bearing race going in through the top opening. Take the bearings one at a time and push them up through the opening in the fixed cup into the greasy bearing race. Use a screwdriver in the other hand from the top to help guide them into the race. For caged bearings, put them in from the top. Note the correct alignment.

It's actually the front walk in area at my business location. Wholesale business, so looks are not important. It also has plenty of neutral walls for picture backgrounds. Servicing the headset now. I have a commercial floor cleaner and clean the carpets about once a month. Cheaper than renting one in the long run.

I have 4 office rooms plus a warehouse. The room behind the window opening is the actual office area. The rest of the rooms are storage/extra rooms. They have bike stuff in them also. It's very nice. I've got to get the main bike room organized, as well as the one with the blue Lejeune.





After the headset servicing, I am working on the Team Miyata and the green Mixte for my son and daughter respectively. They are tired of walking the neighborhood and want to bike instead. I rotate rides on the various bikes. At the moment, I am having to rob parts to get bikes ready for the wife and kids.

How to mechanic Headset bearing service time!
With the aero levers, limited housing, we have to remove the front brake cable. Turn the fork for easier access. 5 mm Allen head is the size.

Use an adjustable wrench to loosen the headset lock ring. The ruler on top of the wrench shows 11/16" or metric equivalent. Use a 6mm Allen wrench to loosen the handlebar stem bolt. Pull the stem out and move to the side. You might have to put some penetrate to loosen the stem. Don't use PB Blaster. This headset has rubber seals. The PB might eat them up. WD40 will work.

Remove the keyed washer and the top part of the headset. Take a picture for future bearing placement reference. Remove the bearings and put them in cleaning solution.

Next, hold the fork/wheel and flip the bike over. Remove the wheel, then the fork. Take a pic of the bottom bearings configuration for future reference.



BTW, fork is stamped with Tange 5L Made in Japan.

quick question from the audience: will a new modern bottom bracket fit in there ? If so which ones? Thanks in advance

It will, but I don't know the correct size. Someone else will answer that. RT or rccardr should be able to go over your options.

Next, clean the cups/bearing races/bearings and check them for pitting, brinelling, etc. Be careful with the seals. If the seals are shot you can find an O-ring that will work. In fact, one of my vendors makes one that works. Contact me if you can't find a replacement.

If you have some bare/rusty spots on the bottom of your frame now is a good time to to touch them up with rust stopping primer.

Hopefully, the cups/bearings are in good condition. Time for reassembly. Grease up the lower bearing cup. Insert the bearings using the pic you took as reference. Put some more grease on top. Insert the fork.
