Glow in the dark.

The Shutter Precision PD-8X Thru-Axle Dynamo Front Hub was scrupulously engineered to be efficient, lightweight, and robust to let you ride through the night. After several iterations of computer-aided structural simulations, Shutter Precision was able to make a a 6V / 3W dynamo hub with class-leading efficiency at a claimed weight of just 420 g without compromising rigidity or durability. Designed with oversize bearings and wide flange distances, the PD-8X can be laced into a bombproof wheel, and the 15 mm thru-axle compatibility means all the stiffness of today's cutting-edge forks can be utilized. If a traditional quick-release is desired, all it takes is a quick insertion of the included adapter.

32 hole. 100 mm spacing. Compatible with 6-bolt disc rotors. Includes connector cap, connector cover, and converter axle from ID15 to ID 5.2 mm.

Great hub, daily performer, built

I have been riding this hub for about a month and it is doing everything I expected it to do. It powers my dynamo head and tail light and keeps me moving and safe on my commute in these Portland short fall and winter days. I am super please with the results. It is a solid piece of machinery and the bike mechanic who built this laced this hub found it easy to build and was jealous that he had to see it go. I also have a PD-8 hub for my older QR wheel. I expect this hub to be as durable as my PD-8. This PD-8X hub also comes with an axle adaptor in case you want to run this wheel on a QR bike in addition to a thru axle bike...which is a nice option if you don't have a thru axle bike now but plan to have one in the future. I wish WBW had more colors (silver), however, the black color is really nice. Only downfall is that dynamo hubs aren't build to be serviced. To replace a broken connector terminal or replaceservice bearings one has to remove the hub from the wheel and send it to SP in Taiwan. Despite this caveat I have no regrets with owning two SP hubs.

Great so far

I only have a few hundred miles on it so far, but they've been worry free miles. Feels more efficient than my (older) SON, and well made. Definitely lighter! Got it on sale, impossible to beat for the money.

Versatile hub design.

I have a couple of hundred miles on this hub so far and it's been trouble free and seems very well built.

I especially like the 15mm thru axle option so I can run it on my mountain bike if I ever decide to do some serious backcountry bikepacking. It's nice that it come with a 9mm QR adapter that is machined perfectly to fit in the axle.

I'm running a B&M front light on it and it has no problems powering it at speeds as low as 10mph.

I had it built on a Stans MK3 Crest rim and it looks great.

Highly recommended as a commuter upgrade. Not worrying about recharging batteries is freeing!

Ive had an excellent experience with a similar Shutter Precision (QR) hub on my commuter bike (2 yrs and many thousands of miles). So, when I needed another dynamo hub for my MTB, I had no hesitation to pick another Shutter Precision hub with 15mm TA. Wheel has been build, but not used yet (planned to be used on multi-day back country bike packing trips this Spring and Summer). I have no doubt that Ill be just as pleased with this one, as Ive been with the other SP dynamo hub.
