Seven Speed Hubs

[Luke Hendrickson]

Yes, these are really, really nice.

Yes...they are good-looking hubs. Did you buy them?

These check a lot of my boxes:  great for low-dish wheels, cold-forged body, steel cassette body, cartridge bearings. I was going to contact Riv with some questions about them, but maybe people here already know the answers:

- Do they include quick releases?

- They're currently 135 mm OLN only. When will the end caps for 130 mm OLN be available?

- Are there any thoughts about getting end caps for 126 OLN?

- What's involved in replacing the bearings and lubing the pawls? What tools are needed? What bearings does it take? Is there, or will there be, a video showing how to take these apart and put them back together?

- Will Riv carry spare parts for these, such as replacement pawls and cassette bodies?

You should email Will about your questions.  I had a similar idea about going 126mm, but I imagine I would just machine down the end cap on my lathe.  Running the numbers, they say that the center to flange distances for 135mm are: 38.3mm and 21.8mm.  If we just lopped off 9mm from the left to get to 126mm, that would shift the center over by 4.5mm, so the drive side center to flange would become 17.3mm, and the non-drive-side center to flange would be 42.8mm.  That's a pretty extreme imbalance.  17mm is not uncommon with 11-speed hubs, but 42.8mm is massive and would mean the NDS tension would be really low.  So, what I'd look for is to see if there's room to take 2 or 3mm off the drive side end cap instead of taking it all off the NDS.  If we could get those center to flange numbers to around 40mm and 20mm, that would be something I could be more comfortable with.
