Try to contact the seller to ask them the dimensions needed for this calculator:

DT-Swiss have changed their ratchet system recently.
This is the old ratchet in a kind of new model skin.

I tried a couple of ZTTO products already, they seem to care.

Their integrated headsets are good.

They make very nice and light flat pedals.

One of their press fit BB(two cups threaded inside together), is on my 062 frame.
Looks like WMFG ones. It is stiff, and the spindle turns freely.
The bearings were not good and I changed them.

And now hubs !!
Thank you for the information.

These hubs look slick! Fovno is making hubs with the star ratchet now as well. I'm wondering if the patent ran out allowing others to make the same design hub and forcing DT to make something new. Either way, I'd like to give these a try but the LBS has already ordered some 350's for me. Maybe on the next build.

Thanks guys!

Yeah, seems like the "old" ratchet system, but at least the most sophisticated one with 54T instead of 18
Where can I like or thumbs up posts?

I hate ZTTO. They made me spend more than I should. I got one of those single speed convertion kit (see pic). And ended up changing my bike's color scheme. So extra expenditures includes 2 oil-slick bottle cages, grips, top cap, and I'm still fighting the urge to get purple cranks or pedals. 

[Colt__Seavers]

Hahaaa, yeah those color schemes are addictive.

Do the colors match from their various products?

Get those cranks! Haha

It would look sweet.

Can't say, I got different brands actually. Couldn't find other purple ZTTO that I liked.

Sigh... hahaha. I'll think about it again when I'm done with the 29er. Need to focus.

Pulled the trigger on these.

Anyone knows how to calculate spoke lengths when at hand? Want to double check lengths given by the seller.

What are your guys go-to for straight pull spokes?  I just ordered these ZTTO hubs but haven't built straight pull before.  I originally was going to go with Sapim Lasers, but now I'm reading horror stories about non-bladed spokes straight pull spokes, at least when needed to service them they just spin and it takes a ton of clamping force to hold the round spoke.

There is something to it. Using round spokes, especially Lasers can be very troublesome. Three very important things you have to comply. Use linseed oil for nippels, destress spokes and Always overturn a spoke and make a quarter turn back. Best is to use bladed spokes like I'll do for this project. You can hold them way better

I recently found that the AliExpress app limits your cart to 100 items.

I think I might try these hubs on my next wheelset.  The price is just too low to ignore.  I could even upgrade the bearings right out of the box and still be ahead vs many other brands.

Believe it or not, hubs already arrived. Pictures tomorrow. Quality from the outside at first look is great. Ratchet seems to be dust dry. Will try to open this evening or tomorrow.
Pictures will come tomorrow.
Weight is almost on point. Rear hub 240g

Anyone knows if I can use motorex bike Grease 2000 in the freehub or should I get DT grease?
