Title: Winspace C5 Aero
Post by: shan on January 16, 2025, 10:22:55 PM
Check out this upcoming release:

Curious qn: Does Winspace make their own proprietary designs/frames or this is from some other factory custom painted and rebranded?

I wonder "how aero" this will be compared to their T1550, which was supposed to be their aerobike. At least the fork looks deeper than the T1550 fork.

Winspace has their own molds.

They started out reselling, but now they have enough cash to have their own.

Could be their most aero bike because they insist on that awful downtube shape on t1500, need to see the whole thing.

Not sure why they call it "allround/endurance"!? A bit slacker steering angle, but same reach and even lower (!) stack than the T1550 2nd generation.

Edit: the steering angle is really slack and a lot of trail at the fork/front end. I think this steers like a truck unfortunately....

Just judging by the medium, it's not that wild of a geometry. Comparing to my (small - but Merida sizes run large) Merida Scultura, it's a similar reach and stack, seat tube angle is the same and head tube angle is only .4 degrees smaller.

Definitely not endurance geometry though.

This actually has the perfect geometry for the general population looking for aero frames. For me (with herniated lumbar disk) it will allow to be assembled with no spacers under the stem other than the necessary for size M, I would not have to go a size down to compensate for reach and give me 9 cm saddle to bar drop. Regarding the "slack" headtube, it will by no means steer like a truck. My Hygge (size S, downsized to compensate for reach) has 71 headtube and it is very precise, rails corners and is very stable at speed and the occasional wind gusts yet remains responsive. I do not like a twitchy frame, and this will definitely be not one. With the price being lower than T1550 Gen 2 and not that much heavier, this is a sweet spot for aero high end Chinese frames, if I can say so. It will be a great purchase for Black Friday this November if it gets discounted or bundled with wheelset.

Odd lack of stack for something they're calling endurance ... but that can be remedied with spacers / stem angle / riser bars.

Definitely good that more brands are finally getting the message about slacker head angle in larger sizes.  But ... they're still slackening the seat angle in larger sizes, and the FC / WB are still pretty short so the slacker head angle will have limited positive effect.

A little better, but not much better.

For anyone trying to sustain a 90-degree elbow “breakaway TT” position over the hoods, you need more stack. This kind of solves that.

Peak Torque speaks on this a lot. Sure you can always use more spacers, but allegedly this will decrease overall stiffness in the front end. Versus running a slammed stem.

The issue is exacerbated with the advent of shorter cranks. Typically you'd need to increase both saddle height and stack height to accommodate the smaller crank diameter and open up the hip angle. So what is originally intended to be an endurance geometry with, say, 172.5mm crank arms quickly becomes an aero geometry with 165mm cranks.

The stack is the same at my XL (550) size T1550, but the reach is a bit less. I think this is probably the frame geometry most of us would actually enjoy.

Looks like a great bike. Honestly think it will sell better than the t1550. To me it’s more attractive as it’s more aero, and a couple hundred cheaper. But ride could be rough. If it’s more refined than the 1550 than it’s really attractive.

Not all of us need more stack to maintan aero positions. Most modern bikes are way too relaxed for me.

Totally agree with the two, but that Cat themed paintjob is sick tho.

I think the 'TdF' one would actually look good if it didn't have WINSPACE absolutely all over it.

At least one paint scheme that doesn’t scream LOUD AND PROUD would have been nice.
Other than that it’s a pretty cool frame. The weight is pretty impressive for a frame with „only“ T700/800 and aero tube shapes like that, I think.

Also the price and the geometry are both in the sweet spot. I’m really looking forward to seeing reviews. I think this could be very popular.

Agreed.  Seriously considering this one, will enquire if custom paint jobs with no logo is possible.

That’s what I thought… You always come in with all these hot takes on every post because you can hide your identity.

think they got the weight down with using a bit of the "M" carbon sheets like in the SLC3. but it is pretty impressive still for it being mainly T800 assume 900g is real weight (chinese frames almost always lie a bit on the weight).

personally, i am disappointed that the stack is not a bit more (for size M) but nothing a extra spacer or two cant solve.

well for starters, people knowing my identity wouldn't change my opinions. Even if I did give you my strava, I don't upload there anyways so you wouldn't learn anything other than my name, which I could give you directly, were I inclined to reveal it to randoms online

I have the C5 and love it. I am definitely getting this one if Bitcoin pumps soon. The geo of the model fits me like a glove, I will however get an extra 10mm in the stem length next time.

How has your current C5 compared to previous bikes? Its “Endurance” but I think the bike seems more racey than they market it as

I like the bike. But I just got an email from Winspace. You no longer get handlebars with the purchase. So essentially the price is risen 20%

Bumping this- considering the c5 aero as they are available complete for like $3k on their website.  Not sure how tariffs play out but it seems like a great deal.  Any updated reviews?  Fit is similar to my current bike with a shorter reach (fine) and a slightly shorter stack.  Longer stays which I’m not a fan of, but bigger tire clearance would be nice.

My frameset in color Roubaix 2025 just arrived.

Size S, weights:
- Frame with hangers: 1090g
- Fork uncut: 471 g
- Handlebar 380/95: 332g
- Seatpost: 197g

Overall pretty happy so far.

Just one thing I noticed (not the end of the world for me):
There are scratches at some points that seem to be underneath the clear coat and probably even underneath the actual paint.

Does it just come from raw frames also having these marks and the paint not being the thickest?


Title: Re: Winspace C5 Aero
Post by: h0ldb88r on August 21, 2025, 02:00:34 PM
You should ask them about that. I don't know how obvious those are under normal usage/light, but I think it would be annoying as a new frame. If that is not to be expected, they could at least give a small amount in refund.

I'm not a fan of those scratches but I also think it's pretty unlikely Winspace would admit anything is wrong if there is. Can't hurt to reach out to them but, in my experience, their customer support is pretty poor :/

I reached out to them and as expected they say it is normal. To their credit, their response was always very quick.
After sleeping about it I also have to say it is fine for me, I mean it is a bike and there are very likely many more scratches to come.
So looking forward to the build.

Can anyone tell me about the customs duties if the complete bike is sent to Europe for $3,200?

According to their website the fully built bikes for Europe will be assembled and shipped from the EU-warehouse, making it costums free.

I finished the build, overall went pretty smooth apart from me making some things more complicated than they had to be ;D
For now I  just threw a lot of parts from my old bike onto the Winspace. Currently running 40mm deep wheels, but my 60mm should arrive soon.

I have just ridden about 50km now, but compared to my old aluminium frame it's a rocketship (as it should be :D)

That paint looks quite cool. What tyre size do you have in those photos? They look quite small and clearance down in chainstays does look quite tight, but maybe photo distorts :).

I currently run Continental Ultrasport III in 28mm on an internal rim width of 18,35mm. Unfortunately I don’t have a tool to measure them, but since these rims are quite narrow, they probably should come in at those listed 28mm.

I've got some Conti Ultra Sport 28mm tyres on 17mm rims at the moment and they measure something like 28.3mm, so yes, they should be just over 28mm on 18mm rims.
