I really like the curved top tube but not so much with it continuing into the seat stay. I personally love the Sklar's signature design.

What is up with the chain in that second photo?
Looks like a nice setup.

Shimano CN-NX01, a 1/2x1/8 chain for SS/Fixed Gear biked. Also known as 'olive chains'.

@AliExpress Test Pilot, I got interested with your 'skipping' ratchet. I have actually been testing the ZTTO 54T ratchet upgrade kit on my DT Swiss 350 hub. And I have great success. I've already done a 1,000km review of it here.

I am 165lbs. I do a lot of long distance rides (70km or more) and we do have a lot of climbs. Bike is a full-rigid 29er XC.

I'm currently in the middle of a follow up review, going for 2,000km. My trail riding had been somewhat limited the past 3 months because the island I go to for that is closed due to COVID. So the follow up review is mostly paved and gravel roads. I'm also conditioning & training myself for bikepacking and had been adding weight on my bike, incrementally every week. This week, I've been riding with an extra 6kg (13.2lbs) so I'm pretty close to your weight. And my target is lugging 12kg by the end of March. As of today, I'm at 1,362km mark and so far the engagement is just wonderful. Should good weather prevail, I might hit the 2,000km by mid March. Clearly, I can't match the punishment you put on your setup but I will be on the look out for that 'skipping' you exerienced.

I converted my gravel bike to a single speeder last July 2020. But let's backtrack a bit more.

Where I lived, SS conversion kit wasn't easy to find. In fact I didn't found any. I've scoured a dozen LBS for a couple of months and still couldn't find one and it's not even COVID related. I did came across one Fixed Gear shop but they only got fixed gear specific. So that's also out. I've contacted some bike shops in another city, they're out of stock (COVID related). And US-based shop have shipping difficulties due to COVID. Short story, Ali-Express to the rescue. Cost me just under US$20 per SS Kit. Comes with spacers, cog & lockring. You can buy their chain tensioner with a kit or separately. I didn't get the tensioner 'coz my frame had a horizontal dropout. In comparison, Surly, my first option was $40 spacer & lockring set, $30 cassette cog. I got 3 ZTTO kits, 16T, 18T, 20T. I wasn't sure if I will be good with a 16T or 18T but the 20T was for the mtb, which will probably be later this year. So 3 ZTTO kits for the price of 1 Surly kit... it's a no brainer even if stocks were available. At the time I got it, it only came in purple. And I eventually spend more purplelizing (if that's even a word) my bike.

The review... I've installed the 18T and you'll be happy to know that I got around 3,000km on it. I've paired it with 3 chainrings, depending on my rides. A 40T round and a couple of ovals, 36T & 42T. I've done gravel rides, muddy rides, roads (a few century & a double century) and even some light trails. Got rained on and even rode beside the sea. And I think you all know when the hills come, single speeders are gonna have to mashed it up. Suffice to say, it was ABUSED. Pictures 1-3 is the unused 16T and Picture 4 is the abused 18T. Doesn't look abused... do I need say more? That one 3,000km picture is enough to say it is worth more than what it costs.

And it now comes in red. Oh, btw, they are aluminum.

I finally got a reply from Adam.

Thanks for the assists carbonnaza.

Strange, I got a few replies from Wing this week and last week...

I'm thinking maybe our mail got in their Junk/Spam folders.
Could you ask Wing to check?

I've personally saw a Tsunami Seaboard (raw version) last 2019 and I have to say I really wanted to buy it. The only reasons that stopped me was they didn't have my size and I was in the middle of a business trip. Although I have to say I wasn't privy with the components as I wanted to convert it to an SS.

I'm kind'a out of touch with the Chinese cf products for a while now. And just want to know the current pricing of a road bike frame set. Doesn't have to be exact prices, just a ballpark figures.

I might as well check out the stock availability. Are most Chiner frame sellers have stocks or there's a waiting time due to COVID?
