Hi Rod, great review, thank you. I also plan on building these myself, probably into Hope Pro 5s. I concur with your spoke observations and will likely also go Sapim Race. Which type of nipples have you used? I thought something low profile would be good, rather than the double squares I usually use. I also like to use a driver instead of a spoke key so the hex head you’re using is appealing to me, which brand and model are you using here?
many thanks
GZA,
How are things in Hertfordshire? I always like to hear what the riding is like in the many places to ride around the world. What's your area like?
In regards to my Zipp 3 Zero Moto wheelset. I really like Zipp 3 Zero Moto wheels. They are one of the best wheelsets I've ever owned. I've beat the living shit out of the wheelset and the wheels are still going strong after 5,000 miles of hard use.
Due to a bad accident, I have an ankle prosthetic in my right ankle. When I pound down rutted trails or rock gardens, my ankle takes a beating and it can hurt badly at times. I built up my 3 Zero Moto wheels to be bomb proof, but also exceptionally complaint. My ankle thanks me for the courtesy....
The single wall design of the Zipp 3 Zero Moto provides the complaince I need. Traditional carbon rims have a double wall design and tend to be teeth rattling stiff. Carbon rims by their nature are less prone to rim damage due to rocks strikes or a poorly timed bunny hop over a curb or log. The rarity with the Zipp 3 Zero Moto rim is that they are strong like carbon but very complIant like an alloy wheel. The complaint nature of the rim/wheel allows for excellent traction. In other words, you're not pinging off of rocks like you would on a traditional double wall carbon rim.
Nothing in life is perfect.....you win some, you lose some. If you are the type of rider who likes to generate energy by using the wheel to snap out of turns, then the Zipp 3 Zero Moto is not for you. The complaint and forgiving nature of the single wall rim means you lose a bit of energy when snapping out of a turn or off a trail kicker. The loss of energy is not drastic, but it's there. If you are the type of riding that values traction and a softer complaint feel as opposed to snappy wheel energy, then the 3 Zero Motor is a rim you should consider.
For my wheel build, I used DT Swiss 350 hubs coupled with Sapim Race spokes. For spoke nipples I used Sapim brass "Secure Lock" nipples. Due to the 3 Zero Moto's single wall rim, the nipples need to be reinforced with Sapim "HM" cupped nipple washers.
I want to point out that I am not a professional wheel builder. My idea of wheel building is to rub two chicken bones over a wheel, say a few voodoo words and keep my fingers crossed while hoping things turn out okay. Yes, that's a bit of a stretch, but I do like to use my local wheelbuilder about what I hope to gain in a new wheel build and the parts I need to achieve the goal. Here is an excellent YouTube video made by Elevation Wheel Building Company. The video depicts a Zipp 3 Zero Moto wheel build.
Important Note: Because the 3 Zero Moto is a single wall rim design, the spokes are fully exposed, i.e. sticking out of the rim wall. If you plan to go tubeless with sealant (Of course you are), the wheel will require a slightly different rim taping process. You Zipp rim requires the use of a small nylon rim strip. The rim strip goes directly over the spoke nipples. You then apply two full layers of rim tape over the nylon rim strip. Using this taping process will prevent sealant leakage via the spoke nipples. Your new rim will come with the rim strip kit in the packing box however, if you buy your rims from a shop, the taping kits may be missing from the box. You can purchase the taping kits online.
In regards to rear wheel hubs, what is strong enough for use on a traditional pedal bike is not neccessarily strong enough for use on a modern ebike. eMTB weight, motor torque, and the extended ride range that an eBike provides, all have an impact on long term component and tire performance. In other words, the shit wears out faster on an eBike.
I am not familiar with the Hope 5S Pro hub. I like Hope products. I find they are well designed, robust and they hold up well to trail abuse. Here is what I would suggest. Every year, new eBike motors are being introduced, i.e. DJI Avinox, Bosch Gen 5, Shimano EP801, etc. At one point 30Nm of power was good, then 50Nm, then 60Nm, followed by 85Nm and now 105Nm. Motor toraue places a tremndous strain on wheel hub bearings and freehub engagement. Whichever rear wheel hub you decide upon, makes sure the hub can be easily maintained and serviced by you. Equally important, make sure that servicable repair parts are
readily available and that the freehub can go the distance. Nobody likes a paper weight sitting in the garage while you wait three weeks for parts to arrive.
Be safe,
Rod
P.S.
I just got back from a quick three day bike trip to Utah. Here are a few pictures if anybody wishes to view them. On day one, my buddies and I rode the Blow Hard trail in Brian Head Utah. The upper section of Blow Hard was fast and loose. The lower section featured a lot of trail kickers, berms and flow trail. On day two we rode Tilted Mesa. Tilted Mesa is a fairly new trail system located near Kanab Utah. The trails on Tilted Mesa are mostly easy intermediate level and tended to be fairly mellow with a few technical sections to keep things interesting. On day three we rode the beautiful but technical, Gooseberry Mesa, located near Zion National Park.
For those interested in a bike trip to Southern Utah, here is a nice article on riding the Zion area. If you have any questions about your trip and or what rides to do, shoot me a message and I'll help you with your trip planning.
Blow Hard Trail, Brian Head Utah. On this bike trip, I ran D.T. Swiss XMC 1501 wheels with 240 hubs and Maxxis Assegai 2.5 tires front and rear. I have a Fox 36, Grip X2, on the front and a Fox X2 rear shock with custom damper tuning.
The scenery surrounding the Brian Head area is incredible
Blowhard exits out of this small canyon
Tilted Mesa, Kanab Utah. The riding on Tilted Mesa is mellow. You can take a beginner mountain biker on this trail system without fear they'll be badly hurt. I enjoy technical rock riding, but it was a nice change of pace being able to just relax on the bike and enjoy the trail and scenery.
Gooseberry Mesa, Zion Utah. The Goose is a special place. Riding along the rim is an incredible experience. The single track twists and turns amongst the many technical rock sections. The rim of the mesa in many places is only a few feet from the edge of the trail. The surface of Gooseberry Mesa was at one point, the floor of a large tree covered inland swamp. As you ride you can see the remains of pertified logs embedded in the mud which is now rock. Riding on the Goose consists of dropping in and out of the many smooth rock bowls and rocky ledges formed by water and erosion. Excellent bike handling skills are required to successfully negotiate the trails on Gooseberry.
If you look to the lower left side of the picture, you will see a white dot. This is the trail, you follow the white dots.
Follow the white dots.......
