- IPX7 waterproof rating
more pros in the video
Cons
- Auto brightness can be dim in direct sun with sunglasses

Bigrock Carbon Crank 24mm For Sram Cranks
Crank
The reviewer installs and tests the Bigrock RS carbon crankset from AliExpress as a potential weight-saving and bike-fit upgrade. They compare it to their existing SRAM Red GXP crankset.
AI Summary
Pros

more pros in the video
Cons
- The weight saving is described as 'not massively lighter' and 'not groundbreaking'
Key Points
- Brand is Big Rock (RS)

RYET AIRCODE
Saddle
The reviewer discusses the RYET (referred to as 'Riot' in the transcript) 3D Printed Bicycle Saddle extensively. They are no stranger to the brand and have used a previous 3D printed model. They are now testing a new high-end 'Riot Ultimate' carbon fiber, 3D printed saddle. They praise its narrow nose profile, advanced 3D printing with variable density (firm under sit bones, soft in the pressure relief channel), premium carbon shell with no flex, grippy finish on the rails, and measurement markings. They tested it on a turbo trainer for a 3-hour session and found it very comfortable, on par with their much more expensive Selle Italia SLR Boost. They highlight its significantly lower cost compared to major brand 3D printed saddles.
AI Summary
Pros
- Comfortable, especially on a turbo trainer (a brutal test environment).
- Narrow nose profile that suits the reviewer's preference.
- Advanced 3D printing technology with variable density (firm for support, soft for pressure relief).
more pros in the video

- It is a 3D printed saddle.

Saddle

The reviewer discusses their experience with this specific Riot model, its comfort, weight, design, and price, but never references the RYET brand or model specified in the query.

LEESE LSE-PRO Carbon Fibre Crank Ultra Light Road GRAVEL Bike Bicycle Crank Arm For E-ASTON Direct Mount Chainring Crank XXE GP3
CrankI have them as well which is why toxin's comment caught my attention. I have about the same mileage on them as you and I'm certainly happy with them for the price. There's not really a better option out there for 140mm cranks. I am however having chainline issues as well despite using LEESE's spider. I wonder if this could be due to the spindle length discrepancies others have mentioned here and on chinertown. Of course this could be due to a handful of other factors so I'm not giving up just yet, but I'll definitely be switching to 1x if I can't get the front shifting working smoothly.

MIXED Full Carbon Fiber 5D Ultra Pack Light Weight Bike Saddle 143mm 135g for Road MTB Mountain Bicycle Carbon Seats
SaddleDuring these latest sales I picked up a Mixed 5D carbon saddle for less than $25. I have to say, I'm quite impressed with it. It fits me a little more comfortably than the last Ryet I picked up (which was a big reason I bought it, because I was a little disappointed in that Ryet). I guess I now have an entire fleet of chinese carbon saddles. If I had to rank them for my personal comfort, this is my ranking: #1 - Ryet X6P (carbon / 3d printed top) [note: I love this saddle. It fits me perfectly and I feel almost no discomfort even after finishing a century] #2 - Mixed 5D (carbon / eva top) #3 - Ryet (idk Superflow?, maybe) (carbon / eva top) #4 - Ryet Aircode (carbon / 3d printed top) I should point out, I've ridden century rides in every single one of those saddles (except the Mixed 5D, since I just rode with it for the first time this weekend). My oldest, the original Ryet Aircode, is the funniest one to me, because I find it rather uncomfortable for short rides. After 10-20miles my butt is a little sore and I would wonder why I hadn't removed it from my bike yet. Then, after 20mi, it just stopped bothering me. Every. Single. Time. I've never experienced anything like that. Of course, I did eventually remove it, because those other ones start out more comfortable and stay more comfortable.
