I bought 2 frames from Winow. The other 2 are Long teng. I prefer the LT, but they're very similar. If I have to nitpick, The LT had better BB tolerances (one of the Winow frames, the BB on 1 frame got in too easy compared to the other 3 frames), the Winow seatpost is too thin to house the er9 battery (irrelevant to you, but pretty annoying).
They're all fine though. Havent ridden the Winow ones, but i doubt i could tell the difference. My friends are happy but it's still winter and they havent ridden much. The geometry is a bit more aggressive on the winow, but that's irrelevant to your situation.
They're bomb proof aero frames for c.80kg dudes, basically.

Hi Peter,

You mentioned that the rim is 125 USD/piece. And the R5026TL disc brake rims 24/24H built with carbon spokes, high end 36T rachets straight pull hubs, 1315g/pair, 2 years warranty, sale price- 625 USD/pair

So that's almost US$375 if we take US$625 mins US$250 (for rim). Trying to figure out where the cost goes to.  There is no detail on the hub but the mention of 36T rachets suggest it's a DTSwiss clones, could you provide more details so that we can see the value of the product.

Example - Carbon type , Hub Type and brand, Bearing type, brands, size. Spokes brand, details .  Could you provide close up photos of nipples, rim, spokes, etc.

I recently ordered a pair of Carbon wheelset (6 pawls) from Kung for US$220/= , excluding shipping. I'm sure yours are of better quality but I would appreciate if you could provide details.

Do you have additional discounts for members here ?
