Coker Rim

Yuck - why are they going to 48 spokes? Once I got rid of the original Coker Rim and the original Coker spokes, the Coker frame and the hub from Coker, I had a perfectly great 36" cycle with only 36 spokes. I can do reasonable sized drops, ride fast, blast over rocks with no problem. In fact, between our 3 wheels built like this, we have unicycled WAY over 10000 miles. Guess how many times I’ve trued any of those 3 wheels? ZERO - Never. No broken spokes. No adjustments at all.

Looks to me like they have missed the boat here. The one thing I don’t want on my cycle is extra weight.


The new Coker rim has offset spoke holes so creative lacing choices are going to be limited.

I don’t think the 36 spokes in a 48 spoke rim trick will work well with a rim that has offset spoke holes.

I can’t believe they are going to make something that heavy even heavier. You don’t need extra spokes just to run narrow hubs. I’ve ridden an 36" airfoil with standard UDC hub thousands of Km’s on and off-road with no problems. Super strong, super fast, and no way am I downgrading to a heavier wheel/wider hubs.



Having a lighter (so also possibly weaker) rim supported by more spokes may work out fractionally heavier, but the extra weight is spread over the whole wheel rather than being concentrated in the rim. It might actually feel more responsive because the weight is on average moved closer to the hub. And anyway, who can honestly say they can notice 60g in a wheel that weighs 3kg or more?

I think the lack of choice of hub/rim combinations will be more of a pain than the weight difference - although I thought the UDC hubs were made in 48 hole versions anyway for freestyle wheels.


plus one :roll_eyes:

You’d be surprised. If that 60g is at the outer section, represented by such things as changing to a 60g lighter tube, you can indeed feel it.

Our 36" wheel technology is woefully behind the times. Seems we had a pretty good discussion thread earlier this year with one of the Coker reps, prior to them finalizing the new design. Many good ideas were suggested, but 48 spokes was certainly not one of them.

Sounds like Coker introduced a product without talking to their customers. Pretty big mistake for any company.


If i consider getting one of the new cokers that are coming out. Then modding it will be my 2nd priority. :smiley:

so far it seems like coker has messed up pretty badly.

they have what seems to be a really heavy frame, that doesnt have brake mounts, and now a 48 spoke rim…

The thing that gets me is that they are making something that really isn’t that marketable at the moment. Everyone is using 36 hole rims and hubs right now. So why would you go and make 48 hole rims when the market and the advantages are dubious at best.

If it was a 36 hole it is already proven that it would be very strong and has upgrade ability, because there are more hubs made for it. Also a crapload of people already have and love 36 hole rims and hubs, so why annoy people by making a 48 hole rim when you can make a 36 hole and make way more money because you will be selling them instantly.

Hopefully the Coker ppl will read these posts and see the errors of their ways! Then it’ll only be another year or two 'till we’ll see a 36 spoke version!:stuck_out_tongue:

Look before you leap

You guys are really tough. We should at least wait until the product has been released, then we can see if, as a complete package it is decent. If Coker makes a reasonable priced uni that is solid, it should sell well regardless of whether some of the components are questionable to this jury.

I would have been surprised if Coker built a top of the line 36” wheel with brakes, form fitting saddle, splined cranks, stainless steel spokes, etc and then sold it for $299.00. But if they build a solid uni that is sharp looking and sells for a reasonable price, they will probably have a hard time keeping them in stock.

With the original Big One, a lot of people bought them as is, not planning on customizing them. Looking for specific features, our best bet would be to let UDC know our desires. They will probably build what we are looking for.

So, before we tear this new Coker to shreds, let’s wait and see what they are bringing to the market.

In case ppl didn’t know, this website sells the radial 360 for the same as UDC, $339…but the shipping is FREE! That’s saving like $65!

Using UDCs numbers the actual weight of the wheel will increase by 65g but if you think of rotational weight (the inertia of the wheel) the difference will only FEEL like 3g evenly distributed as the weight added is closer to the hub.

If you guys think that 12 spokes do not change the strength that much and are so worried about the extra weight they add why not use a 48 spoke set up with 24 spokes? I realize the spoke holes are offset so just use a use two skip two kind of pattern, I have seen similar spoke patterns on road bikes.

If you are content with 24 spokes you could easily lace a 48 spoke rim to a 36 spoke hub using 12 3X and 12 2X (or 4X) spokes

New coker rim with 24 spokes =189g lighter than airfoil and would feel like 251g lighter evenly distributed throughout the wheel-set.

just remember. weight further from the center of rotation will have more inertia, Lighten your tire (or tube) if you want a lighter feeling wheel.

However, to do this would require getting custom cut spokes = $$.

Read the earlier posts in this thread. To attempt 24 spokes would mean using every other spoke hole, which for this rim is offset from the center. Thus you would have a dished wheel.

No, he’s saying “use 2” (right next to each other) then “skip 2” (again, right next to each other).

This should solve the problem of offsetness.

Maybe this 1 is a concept version. Cause the way i see it is, maybe they’re putting pics just to get feedback from people like us. This version may not be finalized yet. :smiley:

But it isn’t; the rim is claimed to be lighter than an airfoil. The weight is in the extra spokes, which can only be moving the weight nearer the centre of the wheel. But I agree, a lighter rim with 36 spokes would be preferable (assuming it’s not too weak without the extra spokes).


As no one has mentioned it, I thought I’d add that the new QU-AX 36" also has 48 spokes.
