There are rest stops every 10 miles so water is no problem. Maybe by then it will even be virus free water.

I'm kind of partial to this version of Powerful Stuff. That mullet Kim is wearing might be the worst of all time.

Two water bottles...

Thanks

Two are enough.

RAIN ‘19 was 88 at 5:30 am, 96 by 10:00 am. Heat index averaged 106 from noon to 6 pm. 170 miles. I barely remember a lot of it.

Averaged 19.9 mph out of desperation.

I kind of like the red spokes. Need to touch them up a bit. Old school carbon wheels, lighter than most. Should be able to go 100 miles on it.

My loaner/beater IM is a "classic" with the same color saddle/bar tape. Not near as snazzy as yours. I'll snap a pic tomorrow at the office.

Here you go. Not as cool as RT's, but it does have snazzy chainrings. We seem to be getting lots of questions about gearing. I have bikes with with the 600 and the 105 drivetrains. I also have all of the props, etc. to give a how to on all of the gear changing possibilities. Let me get some stuff together. I will go over the options, we can discuss it and we can get people set up for the season.

Seypat, you're Classic looks pretty original except for Saddle, Stem, Chainrings, and Pedals. Oh and consumables.
When you Loan it out they're gonna be surprised at the Ride. Those '86 Ironman made everyone want one.

I've got the original chipped ones but I like the feel of the Velox and spend significant time in the drops. The current plugs in my Classic are old dry Velox from a PX-10. My fresh pairs are on my Sachs and my Turbo.

"feel" of plugs? I'm confused.

It's a loaner. Subject to fitting when needed.

I promised a gearing info how to, so let's get to it.
I'm going to cover the options for increasing the gearing using as much of the original components as possible. After that, someone that hot rods them up can discussing modern drivetrains.

You got yourself an IM. You took it for few rides. You really like it, but you need more gearing. What can you do? Changing the rear cluster is probably the cheapest option. Let's pull the wheel and see what we have.

The wheel is off, and it is a freewheel hub marked MF-6208. The one that came on my 87 was a cassette hub marked FH-1050 like the 2nd pic. The Park tools for taking them off are FR 1.2 and FR 5G respectively. You also need a chain whip to remove the cassette.

If it's a freewheel you get another with bigger sprockets, maybe 7 sprockets as well. Or you can find a freewheel with trashed guts and rob the sprockets like this. I got these and the trashed body for $10.

Changing the original gearing, continued.

If the rear hub is a cassette hub, it will be a Uniglide. Maybe later on some would take both UG and HG, but not the earlier ones. Uniglide was replaced by HG and cassettes are limited. You can modify the body with a Dremel to take a HG hub or replace it with a new HG hub. Replacement is better. The new one costs about $20 and you can get a 7 Speed body. Easy to do and How to videos online.

When I am in the drops, the heel of my hand is at times at the end of the bars and I like that soft, rubber, slightly oversized plug instead of the more common plastic that leaves the bar ends rather sharp.

Gearing how to continued.

How big of a sprocket will the 2 RDs take? Let's find out. I have a wheelset with a 28t big cog and one with a 30t big cog. First, the 600 SIS RD.
28T,


30T,





Both need some more chain, but the top jockey wheel hits the 30T with more slack. So, 28T is the biggest you can go on the back.

The same thing happens with the 105 RD. 28T works, but the jockey wheel hits the 30T. 28T is the largest that will work.

If you have the right chain length, both will work with a 28T and a triple up front. That's what I run on my 87. A 12-28 52/42/30 combo.

If you want to run >28T, get a Shimano MTB RD from the same era. Deerhead or Deore. Go to Velobase and figure out which one you need.

That has the rear gearing covered. Tomorrow I will go over the front. If you have any questions or comments, post them and we will discuss tomorrow.

Added bonus:

If you want to know what that color combo looks like with the Conti GP Classic dark gummies, here you go.

I'm already partial to Conti GP Classics. That does look good.

Got a pair on my '89 Ironman. It's a tight squeeze in the back between the tire and brake bridge and occasionally I'll hear some scraping if I run through a puddle or bit of mud. I'm tempted to file the brake bridge just a little to ensure clearance. They've been on dry gravel though -- well, the crushed limestone chat trails on our MUP.

Otherwise, they look good, ride well and don't cost much compared with Conti 4k and 5k tires. And they're true skinwalls, with very thin, translucent reddish-brown sidewalls.
