28 GP4000s almost touched my brakes when I tried them on my ‘87 Expert.

If I'm not mistaken those are known to run big, they might be more like true 30s. Looking at mine, if I have an issue it will be with the fork crown before the brakes (but you may have different brakes than me).

My '87 with 28mm GP4000s
Not just the brakes.

^^^^^ Good thing they didn't put another coat of paint on that fork.

Ha yeah that is tight.
I just got a pair of GP5000s in 28. I mounted them to set of wheels (Zondas) intended for another bike, and they measure about 26mm when inflated--so they will definitely fit with no issue. In fact this is just about exactly what the 25c Panaracers currently on my Ironman measure (on Archetypes).
Edit: picture. These are definitely some small 28s!

I'm curious to know is there a Brakeset that the largest tire allowed is limited only by the frame itself and not the calipers?

I think basically all current Shimano series brakes are like this. At least on mine, in the front a tire would hit the fork before the brakes and in the back, it's about a tie between the caliper and the brake bridge. I have the older 11-speed 105, known as 5800 series, brakes. I would suspect that any current Claris, Sora, Tiagra, 105, or Ultegra brakes would be just about the same. But be aware Shimano changed their brake cable pull at some point and these new calipers may work poorly with older brake levers. If you have older levers I would look at Tektro R539 which would be cheaper anyway.

Some progress on the tiny Centurion. Added the Shimano 105 FD, front brake caliper, Orion drop bars and painted the flutes on the SR seatpost some colors chosen by the future owner.
Waiting in the mail for the 105 rear caliper and derailleur.
Update: RD arrived

did the future owner specifically request those drops? bc as a person of smaller stature...those bars are ginormous.

I seriously doubt the new owner will use the drops. I have deep drops on 2 of my bikes and I rarely use them.
Also finding compact bars in 25.4 clamp isnt easy.
Ironman got the Sora crankset installed. I'm waiting on the black hubs to arrive.

Hey y'all.
Update, still converting my buddy's Centurion lemans into a gravel bike. We're doing a 60 mile gravel ride near the end of May. Anyways, I put a long cage rear derailleur, 10 speed cassette, and tractor tires. The tractor tires just barely rub so I'm working on a fix. I left the original Crankset and DT 7 speed shifters on. It shifts in SiS mode perfectly for the first 7 shifts then it simply shifts in friction the last 3 low gears. That's Cool.
My gravel bike is built from the frame RT gave me, it's a 1×. I shift the 7 speed with friction 600 taken from my '85 Ironman. I've been thinking about putting a Shimano tricolor DT shifter on for SiS shifting but I'm on the fence because I'm digging the bike So much...but I gotta tell you the SiS is convenient. Especially when you only have one bike with friction, I can't get the shift right 100 percent of the time.
I'm still trying to lose my pandemic weight. I started at a all time heavy weight of 200. I've lost at least 10 so far, I'm trying to make 175 or lower.
I competed in a sprint Triathlon over the weekend. I came in 3rd place in my oldies age group. This after not swimming in over a year. The short swim was Cold and challenging for me. I really thought my run time would be faster. But my Centurion Ironman bike Did Not let me down.
I've got the gravel ride near the end of May in which I'll be on the Ironman precursor '84 Centurion Comp TA. Then another sprint Triathlon in Austin on a Monday, Memorial day I may use my '86 Ironman. Then in June, a Exterra sprint triathlon in Waco I'll be on my '88 Diamond Back Apex. Then in July my hometown triathlon in which I'll do the olympic distance triathlon. And finally, if all goes well, in Oct I'll be doing a half Ironman... we'll see.
Here's a pic of the Ironman I used this past weekend.
I averaged 19.something mph on the short 13 mile bike portion. Admittedly the bike portion was Hillier than I anticipated.

That thing's Jet powered? Probably leaves a vapor trail and a sonic boom as you hit Mach 1.

Following up on a build post from February on the 87 MV IM.
Here's a pair that I've put on the local sales lists. Sad to see them go, especially the '85, but they are not being ridden by me.

This is my '84 Comp TA which uses the old style boss and screw thread. I previously had this screw retaining ring on my '85 Ironman with 8 speed Campy. I had modified the cable stop but not the boss. Now the '85 Ironman was missing these screws.
Rather than tapping the '85 Ironman frame boss. (Using a die I found on thebay for 9 bucks), I decided to tap a bottle cage bolt instead.
This not so good pic is taken with my Ironman hanging from the ceiling. I had some flat head bolts but the allen wrench key hole were too small for the force required when using the die with oil. It holds fine So... One day I'll modify the boss for cable stop, as it is, I modified the cable stop.😅

Back when I first replied to this thread I related a story about my '86 Ironman. I couldn't afford one in '86 but in late '87 I could but I didn't like the newest version. So I bought a pinarello frame and tried to replicate the '86 Ironman components. But I would make some slight upgrades. This is the crazy part, I wanted my race competition to think I had Shimano 600 components and I actually would have Dura Ace components. In my head it was like having a dart with a hemi. I know it was silly but I figured if other racers saw my component group wasn't pro level they would let me go. It seems ridiculous now 30 plus years later. But at the time I thought I'll fool them. Besides I was looking for every competitive advantage, that's just what you did. We've all been there Right?
So another crazy thing I did, (which when I think about it could fill a book) was when I finally got my '86 Ironman, I tried to replicate my Pinarello that i had tried to replicate a '86 Ironman.
Are y'all still with me on this. I probably should have just reposted my first post on this thread that I may have explained it better.
So right now my '86 Ironman is exactly built as my Pinarello was. It has Dura Ace hubs, bottom bracket, headset, front derailleur, rear derailleur, and freewheel. It also has a 600 crankset, brakeset snd aero seat post. The shifters are the original 6 speed gripshift on the original scott dh aerobars. This my favorite bike and my favorite setup. It's built as a triathlon bike and all I really need is a 6 speed with the right gearing.
Which brings me to an upgrade a long time coming. I'll be changing out the original 600 Crankset with a same year Dura Ace Crankset. Who knows eventually I may even get a Dura Ace Brakeset... some day.
Here's a pic of my Dura Ace components I may install today.
This 53/39 13-23 will replace the 52/42 and 13-21 Freewheel. The 39 chain ring will be helpful, Not sure about that 53 though.

Attachment 218494Attachment 218493 An 87' model, Master in yelloow/white. All 600 but the hubs, RD, and it was updated to 7spd. Looking to trade for a 53Master any color, look for me in the pass around game.

I bumped into this guy as well as BF member rccardr yesterday on a ride. He was doing all right and getting good grades. As you can see, he has on sunglasses. I was riding one of my Centurions. He was on a yellow/blue Nago. rccardr was on his yellow C'dale rocket, I think.

rccardr,
Speaking of that "furnace" ride yesterday, lots of discussion around me about how to cut the severity of the ride while still getting your distance. I heard a lot of good ideas about how to cut the mountain out all together and use hybrid courses of the 45/75/100 routes to make a route 60-100 miles while still using the SAGs. Probably what I'm going to do in the future. That was a tough ride yesterday. Even the greatness of a Centurion Ironman bike cannot take the sting out. I'll either drop back to the 45 or figure something out. It was rough.
