I got a 36 hole open pro rim for pretty cheap, and I want to practice building a wheel from scratch. i don’t want to break bank, but I want to put on a good hub.

im looking at the latest r7000 105 front hub for $32, but I was wondering if there’s any other hub I should look at.

This will eventually replace a wheel for my single speed. I’m fine with building front or rear, although 105 doesn’t seem to have 120mm.

what would you suggest? I’d rather match the hubs once I find another rim to build.

I don't understand the question. Is your title asking if you should use 100mm or 120mm hubs? It's based on your dropout width.
About the Shimano model, I haven't looked at the front hubs, but I did research on the rear hubs, which might be the same situation as the front hubs. For the rear hub, rs300,rs400, 5800 and 7000 seemed to be physically very similar from the exploded drawings except for lighter QR skewer assembly on the rs400, 5800 and 7000. Rs300 didn't show any polishing on the cups and cones in the specs. Rs400 does list polishing. Rs400 can be found really cheap. Looking at the assembly manual, rs300 and rs400 are probably identical except for the polishing. 5800 and r7000 are also probably identical, but they have a hex socket at the lock nut, instead of the traditional need of 2 cone wrenches on the rs300 and rs400. The 6800 and similar expensive models uses a dial lock washer that you can rotate around to set the preload on the bearings to prevent the cone from rotating as you tighten the lock nut. The specs say labyrinth seal so maybe slight better water shedding, and lighter aluminum axle.

Otherwise I think they all would perform very similarly.

Search the Shimano documents site for the exploded drawings and assembly instructions.

sorry for the confusion.

im looking for suggestions on specific brand/model of hubs to be used with 36 hole rim to build wheels for either 100mm or 120mm.

most reputable brand I found, even places like vélo orange, seem to have just 32 hole hubs for single speed.

If you need a hub for 120mm rear wheel OLD, it's usually not hard to use a wider hub and simply trim the axle and remove spacers to get that width. Even better if the hub isn't built into a wheel yet, because you don't have to re-dish after trimming and re-spacing. If you're using nuts rather than a quick release to retain the wheel, you don't necessarily even have to bother trimming the axle.

Shop EBay for older stuff. My favorite for current (and older too) is Phil Wood. Used Phils tend to be in better condition then other equally old brands. I have a pair of Campy Low Flange NR hubs still in their box but forget if they are 36* or 32*. PM me if you are willing to spend some money Andy

I think you will find new 36H hubs pretty rare these days so finding a matched set is not going to be easy. The matching R7000 rear hub is available in 36H but is set up as 130 mm, 11-speed. Narrowing it to 120mm OLD will leave the wheel with a dreadful amount of dish. Finally, finding another 36H rim for the rear wheel is going to be equally difficult.

I think you are going to a lot of trouble to be able to use that "orphan" rim. Buy decent 32H rims and your problems are over.

Are you looking for a 120mm track hub?

in the worst case scenario, I’ll just run a 36 for the front, for which the hub is easier to source, and 32 for the rear.

what’s an OLD?

curieux88

ideally a matching set of track hubs with 36 holes.

I don't use track hubs even for my fixed gear wheels because I prefer quick release. So I'm not too familiar with what's out there. But I'd avoid the super cheap cartridge bearing hubs which seem to have bearing failures more often than they should (from what I hear.)

If you're looking for a set of track hubs, these should do the job nicely though they are slightly non-matching: https://www.ebay.com/itm/Ofmega-high...EAAOSw5CNesxWK

Here are a set of 36h road hubs. You could trim the rear down to 120mm. That they're also Ofmega is strictly a coincidence... https://www.ebay.com/itm/VINTAGE-OFM...8AAOSw9gRaNUnl

"Over Locknut Dimension", i.e. the width of the hub between the locknut faces and the inside width of the frame's or forks dropout faces. In your case you want an OLD of 120 mm for the rear hub and 100 mm for the front.

I don’t have knowledge of track hubs. I think Andy is right on with Phil hubs. High end will cost, so better 36 hole options are out there if your wallet is “open” to those options.

I have seen Dura Ace track hubs on eBay when looking for freehubs. I have always liked Dura Ace. Regardless, eBay is a good source.

If you want to wade through the meandering of this thread, you might glean some direction.

Is there not a co-op option here? 36* hubs are easy to find in the co-ops. Sometimes it is easier to cut out the hub in an existing wheel and start from scratch. Smiles, MH

Here is a typical , Taiwan ? Hub set they are sealed type bearings . 36 holes no problem there are lots of them on the bay high and low flange . (Won't break the bank) .
