LTwoo calipers are bricks. I'd rather source some Shimano calipers if possible or use lightweight ZRace/IIIPro calipers.

I've tried this, just wanted to warn that they aren't super great IME. I'd source shimano calipers instead.

I don't see what makes the Evo non aero or a aero larp because it's cheap. 
I think people have complaints about various things but no one has said it's slow aerodynamically. Cam Nichols had it as his fastest bike in a descent he tests aero on, and he wasn't too keen on it overall.

My thesis statement on the Elves Evo's aerodynamics is that it's a bike designed and marketed as a full-on aero road bike but if you closely examine the design itself, it seems to ignore many important principles of aerodynamics and other important considerations, and does so in such a way that prioritizes the aesthetics of aerodynamics over things that actually make it aerodynamic. This is why I call it a LARP: it's trying very hard to play the part, without substantively doing so. This "aero aesthetic" compromises other important qualities, specifically comfort, stiffness-to-weight ratio, and ease of manufacture. If an aero bike is designed carelessly like the Evo appears to have been, then all this added weight and complexity is squandered as you'll find other substantially lighter and more comfortable bikes that are just as, if not more aero.

You see western brands making this point. We have bikes like the Cannondale Supersix Evo 4 and the Tarmac SL8, which are "all-round" frames that compromise the aero aesthetic, but nonetheless are just as (if not more) aero than the full-aero frames produced by the same brand (see Tour Magazin tests thread on WW). To me this is a clear signal that the most substantial aero gains are to be made not in deep section tubes, but instead through careful implementation of aero design focused on surfaces that meet clean air. I'll get into what these features are in the next paragraph, but I'll make the point now that I doubt the Elves Falath Evo is substantially more aero than it's predecessor, or competing frames like the ICAN A22, Seka exceed, Blize, etc.

Really I have 4 big criticisms of the Elves Evo design: rectangular tube profiles, headtube and fork junction with huge cross-sectional area and bad design, enormous gaps between tires and the frame cutout, and no bottle fairing.

Rectangular tube profiles: I don't really need to explain myself here. It's objectively not as optimal as tubes with round leading edges.

Headtube: arguably it's the most important part for aerodynamics. Everyone else is working to make the headtube as narrow and aerofoil-shaped as possible. The Cannondale Supersix Evo 4 is a great example. Much ink was spilled over the specialized speed sniffer. We've known the headtube is important since forever ago, just look at the Specialized shiv from 09, which had a big nosecone strapped to it. In contrast the Evo has the widest headtube I've ever seen. Oversize bearings and no effort to taper the headtube between them. The headtube cross section is short and distinctly not-aerofoil-shaped. AND the fork crown is crazy thick.

Cutouts: cutouts work great, but they only work if the gap is minimized. Bikes that aren't trying to optimize the cutout simply don't have a substantial one (see the latest Specialized Shiv). On the other hand, the Evo pretends to have fully-faired wheel cutouts, but then in a bid to get 32mm of clearance, spoils the party with enormous spaces between the wheels and frame. This obviates the cutout entirely. It would probably be just as aero to have little to no cutout at all in this case. But the Evo has them, because the Evo is committed to the bit and needs to look like an aero bike.

Bottles: We all ride with bottles. Bike manufacturers have finally caught on to this and started fairing the bottle with the downtube instead of mounting the bottle on the trailing edge of an aerofoil like they used to, which totally spoils any aerodynamic benefit you'd get from the tube section. Elves seems to have not gotten this memo.

Now, this is just me and my eyes looking at the frame. I'm sure it's more aero than other frames. I am definitely sure many frames are more aero than the Evo. And most of all, I do not think the Evo is a good bang-for-buck in terms of aero performance for the weight and money it costs.

Saw TONS of the GR029/FE806 frames in the New England CX circuit this fall. All the SmartCycle and some of the NE Devo guys are on them. All seem to be quite happy with them.

Another update on the skinsuit hunt: anyone here tried KIAE? These look like properly expensive suits unfortunately, but seem to have the latest-and-greatest aero tech + premium EI pads.

Okay so now that I’ve done some digging and research, I’ve come upon Switfoto, which sells skinsuits and speed suits with an “Italy MITI” chamois…not really sure where it’s actually from but I trust it’s not trash. Suit has good reviews and aero sleeves, which is what I really want.

Has anyone tried these Goldix XDR road cassettes? I'm not so concerned about the 10t cog, I like how the cog sizes are spread out differently for cadence purposes. Now only if I had an XDR freehub on my wheels...

I've got one, I'm running a 10-36t with Sram Force AXS RD (rated for 33t max ) on my cyclocross bike. It's been flawless. Super light, installed easily, shifts just fine.

Anyone got recommendations on a one-piece skinsuit (preferably with pockets)? Looking to find a 'racesuit' type outfit but it seems like there's not much choice from the high quality brands on AliExpress.

As a fellow skinsuit-enjoyer, I've also been looking for one. Here's what my searches have come up with:

-VV Designs/VV Sportswear: Reviews show pockets. Reviews also show the fabric doesn't have aero-ribbing like the photos do

- Spelispos: Aero ribs and pockets--bingo! Except the "real" photos show the shorts have a seam, not that seamless compression band. Bummer. It's a long sleeve, but I have good experience just chopping the sleves in the past to make a SS.

-Velotec: These seem to be the nicest quality, but they also have no reviews. The long-sleeve models have a SINGLE pocket. The open-front-zip model seems to have two pockets. I'm also extremely confused by pricing, the Velotec website doesn't look like a "western" company, but the prices are 10x what they are on AliEx.

Lastly--anyone have experience with these "9D" or "20D" pads they put in these? It seems that across all the companies, you get a "9D" or "20D" pad, I'd love to hear some testimonials on what they're like.
