Hi Everyone!
I'm new to these forums. This being only my 2nd post, since my introduction.

I have what seems to be a rather uniques position in today's market of cycling equipment and parts. First, I need to declare that I'm a mature rider in my 50's; and I've largely done my own bicycle maintenance, as long as I've had the tools. Next, I need to be upfront about my bike: It's a Miele Gara '88 with a Shimano 600 Ultegra groupo (Yes! I bought it new, in 1988) It's in pretty good shape; and the reason that I've kept it is that I'm 6'6" tall; and the frame is triple-butted, which suits my size very well. I've maintained the Shimano groupo; and I'm still quite happy with it. I can't justify spending thousands to simply replace the groupo, when I'm only riding for pleasure. Also, I suffer from sciatica; and the Biopace crank allows me to be able to cycle without any adverse effects. (I lucked out with that)

Here's the interesting part! Last Summer, the Ambrosio 19 rims that came with my bike finally died, after untold thousands of miles of use over the decades. They saw me through racing as a novice; charity rides (including centuries); and me simply being a silly drunk young fool. So, now I'm looking to build a new set of rims for my bike; and I've got my eyes on the DT Swiss RR511 rims (non-disc brake). Why? Because they're solid rims, which will handle by weight without any problems (as I get back into shape). Back in the 90's, I would simply have gone into the bicycle shop that I purchased my bike from; purchased the rims and spokes; and simply rebuilt the wheels. Today? I've encountered what I can only call strange behaviour! Bicycle shops are refusing to sell only the rims and spokes; and some have even claimed that my Shimano 600 Ultegra rear hub/sprocket is "incompatible" with the DT Swiss RR511 rim. Again, I declare that I'm not a bicycle mechanic, but as soon as I heard that last claim, red flags started to go up. I'm getting the feeling that people are trying to take me for a ride $$$$$.

I understand that with the DT Swiss RR511 rims, I not only need to use all new spokes, but I'll also get matching nipples, as well as the PHR washers; and I don't plan on going tubeless, as it's not necessary.

So, the question that I have (in multiple parts) for anyone who has a great deal more knowledge than I about bicycle mechanics than I do, is:

• Can you think of any reason why I can't use my existing Shimano 600 rear hub/sprocket, which would prevent me from being able to use the DT Swiss RR511 rims?
• If the answer to the previous question is "yes", can you explain it to me in terms that I will understand? (Admittedly, I'm extremely skeptical; and I need to understand why)
• If you think that this should NOT be a problem, but that I should be aware of any considerations as I build my new front and rear wheels with the DT Swiss RR511 rims, could you please share that knowledge?

Hopefully, I've chosen the correct thread in this forum. I searched through all the available options, but couldn't find anything more apropos.

Thanks in advance!
Mick

You don’t mention the number of holes/spokes in your existing Tricolor rims, but unless they are an unusual drilling, should be no problem. Those DT rims seem to come in all popular hole sizes. Personally, I’d go with Kinlin rims in that aero size, but hey, you be you.

BTW, kudos to you for keeping those Tricolor hubs in service. They will likely survive you. And me. And a nuclear holocaust.

I've never used those DT rims, but it's still just a rim. If your hubs have the same number of holes, you'll be fine, have fun. The only incompatibility I could see would be if your 600 hubs have 36 holes, because the RR511 looks to only be offered with 32 as the highest drilling. If you have hubs with the same number as the rims, then your LBS is trying to take you to the cleaners.

maddog34

are your 600 Hubs 32 or 36 hole? 36 hole is not available in that rim...Excellent hubs, no matter the spoke count!

here's the Numbers for the 32 hole DT swiis rim with Rim Brake Tracks ...

RR 511 700C 32 mm RB VI

...if the case turns out to be that your hubs are 36 hole, replacement rims are still available that are drilled for 36 holes. Just not those.
There were some shortages and out of stock problems a couple of years ago, when last I bought some. But I think that was Covid factory issues.

The DT Swiss RR511 does not come in 36 hole, only 32 hole or lower. I don't know if it's true that you need to use PHR washers with these.

Another great DT Swiss rim is the R460:

These are a great bang for the buck. I built up a set of these with Dura-Ace 9000 hubs, DT Aero Comp spokes and DT brass nipples (no PHR washers). I have logged over 10K miles on these and have not had to re-true them once. These also only come in 32 hole or lower counts.

A bike from 1988 would have a high probability of having 36 spoke wheels. 36 hole rims are not impossible to find yet, but fewer manufacturers are offering them. Even the Ambrosio classics are topping out at 32 hole.
Velocity fusion would be a good choice for that bike. A 25mm profile and 14mm inner width would suit it well. Available with all drillings from 18 to 40.

The h plus son archetype could be another good option if you need 36h

roadcrankr

You mentioned "thousands of miles," but not if you periodically cleaned & rebuilt the hubs.
For example, if you rode these 50k miles and never rebuilt, the races and cones could exhibit pitting/wear.
Riding in wet conditions could contribute to premature wear, too. Spin the wheels by hand to feel for any grinding action.
Sounds like 7-speed hubs and 130mm rear spacing. Betting you could find suitable replacements online, if needed.

Lombard

These would be an excellent choice as long as you get silver. The black ones don't have a machined brake track so will look ugly for at least 500 or so miles until the black is worn down.

If the OP wants a silver HPlus Son rims and Miche hub wheelset - choice of freehub - butted spokes - here it is for $359. Just under 2000 grams if that's you're thing.

I bought a similar rim brake wheelset from Velomine - 28 hole H Plus Son silver 700c with 105 hubs. Very nice so far.

Apologies for the delayed follow-up. Our place has been in a buzz with other priorities, since my wife’s return from visiting her family in China.

I really appreciate all of your replies! And yes, I should have included that my Shimano hubs are 32H. You’ve all provided some good recommendations. I’ll look into them. One of the reasons I have my eyes on the DT Swiss RR511 is that it’s much more durable than the Ambrosio 19’s that I’ve enjoyed. Whichever rim I go with should handle the weight of my 6’6” frame, as well as the combination of imperfect roads, railway crossings (I can’t hop as well as I used to) and the occasional trail (more like paths that the local government has cleared for people to walk, run and ride bikes on… not rough, but not as smooth as pavement).

I agree about the Tricolor hubs! Back when I ordered the bike, I deliberately chose the 600 Ultegra groupo, because it had a great reputation. The store actually offered to install a Campagnolo groupo for the same price, because they didn’t have the Shimano in inventory, but I decided to wait the extra couple of weeks. The hubs are easy to maintain, too; and yes… they still spin freely. They only time the wheels made any grinding noises was when the rims went out of true; and rubbed against the brake pads.

Well, I have my homework… to check out those rims you’ve all recommended. I may still go with the DT Swiss RR511… who knows? Maybe one of those recommend?

Once again, I really appreciate the feedback!

If you're strong, heavy or pack cargo, I'm a fan of an OC spoke bed rim like these-

I was going to say that I like the OC rims FOR THE REAR WHEEL. Most of my rims are the Aerohead rims which are slightly narrower than the A23. But the A23 should be fine.

DT Swiss does make what they call Asymmetric Rims for some of their models. Probably other brands too.

You may need to calculate your own spoke lengths. There are several good spoke length calculators online. And, you can measure your own hubs.

Now, one thing to keep in mind. Well, I like the newer triangular shaped rims. But, some purists like the flat top rims on vintage bikes. You can find a variety of rims on E-Bay.

Or the company Velo Orange will have some vintage looking rims.

This would be the time to upgrade should you choose to convert to 9 speed, 10 speed, 11 speed, or even 12 speed. Friction shifting can work with newer cassettes, if you have the range with your derailleurs.

Make sure your hubs are good with good cones.
