I finally got my new trials wheel together, and a chance to ride it.
Experience from the zhi on my bike (and logic) told me the rim would fight some roll and let me play with lower tire pressures. Now that i have actually felt it, I’m suprised at how much stability it actually gives. I can use a much more comfortable tire pressure, wich gives more grip and bounce than the pressure I was forced to run on the dx32 to fight tire fold. Even the “dead” luna had some spongyness. It dosen’t eliminate fold, but when it does, it’s less severe. Those who like to play around on natural trials will especially appreciate the extra width on this rim.

I am digging the geo on these cranks. 137 feels really nice to pedal, and dosen’t give up too much torque. Even though they only flare out 5mm they feel a little wider, and more stable than profile cranks, maybe they mount further out on the axle. The spacers between the cranks and bearings wheren’t doing anything usefull, so I left those out.
Thanks Darren @ bedfordunicycles.ca
Sapim (sa-PEEM) strong spokes. What can you say about a spoke? So far, they’ve keept the hub connected to the rim. They get fat at the neck/head, then turn into a regular spoke for the rest of the lengnth. The wheel felt stiff when I was lacing. I’m sure it affects the ride, and energy returned on my sidehop. I would use these again.
Thanks Richard @ wheelbuilder.com
During my hour and a half test ride, I added nearly 2" to my sidehop!
Pics to follow.
the Echo rims only come in 32H, but it is still possible to build a wheel out of a 36H hub and a 32H rim.
The Zhi rims only come in silver 36H. I myself went to China during the Summer, and looked at some stuff to buy for my mod trials bike, the owner of one of the shops is a friend of Yao Zhi (founder of Zhi Bikes) and told me that Zhi only made 32H rims in colours, whilst leaving the 36H rims in just silver. Aside from that minor colour issue, it’s a good rim I guess.
Try-All isn’t worth getting unless you’ve got a good reason. The only rims from Try-All I would recommend are the new undrilled and eyeltted rims seen on the Dan Heaton Pro Street and Orange Bud unis, and they’re pretty wide themselves at 46 or 47mm wide or so. Infact, I’d say they’re the best rims around now. The Zhi rim will die much sooner, just like a Try-All, I’ve seen plenty of Zhi rims die first hand myself from riding with fellow biketrials people in China.
Most of the strength of a wheel comes in its lacing. I have sold over 100 of the ZHI rims (to biketrials guys) and had not had an issue. This is not just the case with ZHI because I sell them, pretty much all the other brands have held up pretty well. Years ago Monty had rims made by a company called Akront… nasty, the gap at the seam you could actually stick several sheets of construction paper into! Point? they did not fail either… as crappy as they were, they were built correctly.
Either the ZHI rims you saw in China were completely different model than what shows up here, or someone needs to learn how to build a wheel.
