s40 gen 6

Can’t wait to see more about what has changed! Carbon front end? Adjustable seat angle?
Front end and seat angle look the same - I doubt those areas changed. My guess is that the components are back to SRAM from Microshift is going to be the main change we see - I am hoping for 145mm cranks, but I doubt they won't show up for at least another year

Getting away from Microshift and going back to the SRAM components is a really nice change from the previous Gen

I hope it’s more than just components and colors. If not, it hardly merits being called the next gen since you can always change components. Let’s see what is revealed in the unveiling later in November. Hopefully some surprises will emerge!

ya'll - the marketing photos depict a conventional circular steering column, not bladed like the v20c. Carbon's unlikely.

Yeah, I hate microshit components. I will upgrade my s40 to Shimano asap.

I wish to have s40c (carbon version) of s40. Ideally full carbon not only partly like v20c.

The only thing I would to change on the S40 is the seat. It would be cool if it came pre-installed with the adjustable carbon fiber seat.

The drivetrain groupset, wheelset e.t.c can always be changed by the user.

The carbon front end from the V20 would be nice, but I would think based on the number of comments on this forum about recumbutt associated with the S40, perhaps an adjustable seat angle might make the biggest impact.

yes there seems to be consensus that the Silvio with around 30 degrees is like a 'Goldilocks' seat angle. Having a model that can convert between 30 and 40 degrees would be great.

A full carbon frame for the S40 (or any model) would probably be heavier that the aluminum hydroformed frame - it is extremely light and strong. I have "Magic" which is 100% carbon - and it is 5 lbs heavier than the V20C.
Extremely light is not what springs to mind. Among the heaviest recumbents I have owned.

I suspect that a well-designed carbon frame for a Cruzbike would be lighter. It could also be more compliant and comfortable as well as stiff where needed. The trick I believe is the cost to engineer develop, test and make it. With a claimed weight of 3.7 lbs. for the actual frame and 12.14 lbs. for the frame set, I do not think that a minimal weight saving on a carbon frame will make the bike too much lighter. Given the already costly frame kit I am not sure any of us would be willing to pay the price for the weight saving.

I did notice that Slyway claim ~9.5 lbs. for their frame set, though not sure what is included or the weight of a competed bike.

Just for fun I looked up the frame weight for a Trek Domane Carbon frame and it is ~3 lbs. and the complete bike was 19.4 lbs. I am currently building a V20 c and if I take the frame set at 12.14 lbs. and add component weights, I come out around 23-24 lbs. I have been impressed with the weight of the front-end components compared to my Q45.

More details coming but no "major" changes here as far as frame/geometry are concerned. SRAM components and TRP brakes are ones that I had on order since mid-covid and they finally arrived and have been waiting for this batch. That alone makes this a much sweeter ride. The colors are SWEET and our painter did a great job - maybe the best yet. A few small changes but it is hard to tweak something this good.

As has been mentioned - it is near impossible to make the frame in all-carbon from a manufacture/cost standpoint and have it be lighter than it already is. If it were the same weight, the rider weight would be capped at like 110 lbs.... so hycroformed aluminum for the win as always. This is something I investigated even before we built the first S40 homebuilt prototype. For a home build it might be able to be light - but would then also be flexy and able to carry zero weight. The carbon manufacturers don't mess around with the specs on things they feel is too light and flexy.

Also, I have held a SlyWay frame in my hands and it is not light.
 
I think the best upgrade on an S40 frameset would be a ventisit seat pad as standard. From what I've read on here I'd love one but it would cost me at least 50 euro (75 from US) in postage to get one to Ireland.

Thanks for sending that pivot clamp btw. TRP and SRAM 1x11 is exactly the upgrade i did to 2023 model.

In my opinion the best change in the S40 would be a 1x12 groupset instead of 1x11.
I am somewhat biased because I live in the mountains, have grown old and only have half the power I used to have 30 years ago. :(

I received this email with 6 gen update features:
  • Gen 6 sees the return of SRAM components.
  • Full compressionless cable housing upgrade for both the front and rear brakes. (I don't know what this mean)
  • The S40 Gen 6 will ship with the epically comfortable, incredibly adjustable Suspension Adjustable Headrest so you can get your fit dialed in right out of the gate.
  • Refined derailleur hanger design for an even stiffer integrated front triangle
  • Three gorgeous new Gen 6-exclusive colorways: ember, forest and summit gray (sounds nice! )
