My SP-8 has like 25,000 miles on it and it’s doing fine. Moving it to my wife’s bike
The SPs are getting better i think. My PV8 is about to be retired to B-wheelset duty after 20000 kms. It replaced 2 RMA’d ones in a row.
Word is though that the little SV-9s have lighter duty bearings. I dithered about this for so long and just would up getting a SON28 for $300 cad shipped from spa cycles in the uk. My infernal math was, it is twice as expensive as SP but would make me feel happier than two PV8s.
The new xts look really sweet too. Fully serviceable bearings, as light as schmidt, and you can get cones for them with some quick googling.
SP failure is overstated atmo

There’s a new Shimano jawn. They’re claiming 44% less drag compared to the T8000.

recent cyclingabout test writeup shows UR-700 gives a bit more light at the cost of a lot more (lights-on) drag vs. competitors (if I’m reading it right).
I’m thinking about grabbing one for a ditherbike, the trade-off might be fine if one is anal enough to switch lights off during the day…

is this T8000 or UR700 or something else?
Need to add that to my reading list
I haven’t switched off my dynamo lights in about 8 years.

Wow, there is some pretty detailed info in there. Well worth taking the time to read properly.
Key Talking Points for the kLite Bikepacker Ultra:
– The Shimano UR700 hub provides the most light from 5KPH to 17.5KPH, with a maximum brightness at 20KPH (6-watts).
– The SON28/3D32 hubs offer the most light from 17.5KPH to 22KPH, with a maximum brightness at 20KPH (7-watts).
– The SP PD-8 hub offers the most light after 22KPH.
– Compared to the SON28, the SP offers 35% more power to the light at 25KPH.
– The drag is lowest for the SON28 at maximum power (18-watts), but not by much.
– At low speeds, the drag is considerably higher with the UR700 hub (but you get 10-25% more light).
– The drag is 24.5-watts(!) with the SP at maximum power; if you want a bright-as-hell light, you’ve gotta pedal hard for it.
– Average lighting efficiency between 10-30KPH: SON28 (42.6%), 3D32 (38.2%), PD-8 (32.7%), UR700 (31.3%).

man. does anyone know when these new shimano become readily available? i will buy one right now.
They’re available now, but maybe the drag isn’t as low as claimed based on the tldr; summaries above.
yeah but i have the sp. anything’ better than that it looks like
You do you, but there’s less expensive Shimano options if you’re just looking exit SP lyfe (been there).
I’m about to start using a 3w Alfine jawn. I’ll report back.
I just ordered some stuff from bike24. They seemed to have the best combination of cheap shipping and light selection. Shipping is taking a minute (10 days to ship cuz stock; 7 days & counting to cross the atlantic) but I was expecting that. their estimate was 16 days total
