Hi All,

I have pulled the trigger on pre-ordering this [/https://www.yishunbike.com/product/r1058-dperformance-road/] .

Melinda tells me it is still in development but that it has passed their quality test and will be dispatched in 3-4 months. It's 1070g for a 54cm so is pretty light, they advertise a lighter version at a claimed 900g for 54cm which would put it in roughly the same category as a seka exceed for a third of the price. However, Melinda tells me this version did not pass the QA tests and anyway requires a minimum order of 10 units, I expect this version to be available next year. It lists something called 'One-piece 3D latex mandrel' aswell as one-piece molding which I assume is how they will achieve the lower weight, this feels like a new technology and evolution from EPS? Anyone know anything about it?

Yishun say: 'The newest latex 3D mandrel monocoque technology improves the strength by up to 30% when using the same material due to the smoother inner wall without wrinkles inside.'


'700c Full Carbon Performance Road Bike Frameset

– One-piece monocoque moulding

– One-piece 3D latex mandrel

– Fully internal cable routing design

– Max Tire 700*30C

– Max Chainring 55-42T'

Looks-wise I think it resembles an SL7 with slightly more relaxed geometry. The resemblance is not surprising after reading on their website that 'The R&D product chief manager had worked as one of the product managers in the Specialized OEM frame factory for 6 years and gained experienced skills in designing and producing carbon frames.' I'm guessing this would be Ten Tech Composites?

They also say that they OEM for '-several well-known brands around the world, such as RIBBLE, BERRIA, MENDIZ, MAGEMO, BOTTCCHIA, DEROSA, and so on…' which is encouraging.

On paper this should be a great frame, however it's obviously a bit of a gamble and the first frames in particular may have issues however it appears like they have solid quality control and testing aswell as warranty. You can pay 20% more to get a 5 year warranty which is a nice touch assuming it will be honoured if something doesnt go to plan so I have opted for this option.

Standard version without handlebar and 5 year warranty: 718usd, shipping 185usd, there are also different charges for payment methods. 5% paypal charge and 30usd bank transfer charge. Will update along the way if anyone is interested.

Fingers crossed!
