A detailed picture of cable configuration (this was taken 2 months ago, when I used 9100 mechanical grouppo with TRP spyre)


Future Plans:
1. Buying a pair of Bike Ahead's centerlock adapter, "The fixer"
it marginally shaves 18-20g total.

2. Darimo's Loop saddle clamps
Original apparatus weighs 50ish grams (cradle, yokes, bolts, certer rod)
and Darimos one weighs 10g (without center rod)

3. Xpedo SL ti spindle pedals.
Swapping right non-PM one to this cuts 42g according to this forum.

4. Sroad SLR2 11-28 cassette.
it weighs around 185g, which is definately lighter than shimano 8000 11-30 269g

Looking great! What was your process for deanodizing and polishing?

1. any sodium hydroxide solution. You can also use drain cleaner or drain opener (2-5% of NaOH)

2. 400, 1200, 3000, 5000, 7000grit sandpapers

3. plenty of elbow grease or a rotary tool.

2022. 12. 26. Swapping cassette from Ultegra 11-30 to Sroad 11-28


Image
Ultegra 11-30 275g


Image
Sroad 11-28 181g --> -94g


6.75 --> 6.66kg


* Personal experience.

I have not ridden it for longer than 50Km thanks to the frozen holiday climate.
Crispy shifting and No worries (Yet..) But I heard that Sroad's parts only does not work with shimano's shadow derailleur versions. However I am still afraid but happy now..




*Upcoming Items (parcels are on delivery YAY)

1. Ashima AC05-1 6bolt adapters. 21g*2
My current option is DT adapters 60-62ish gram. (I dunn remember the exact number..) so 18-20g will be off


2. Xpedo Thrust SL pedals. I will use NDS - SL body with Assioma PM axle/ DS - Thurst SL.
According to a WW user "mattsurf", this combination weighs 218g (Original Assioma Uno weighs 282)
So hopefully another 64g off..

Result: 45-56 == -11g


Image
Thrust SL ti axle.
Image
Original Assioma's drive side one

Result: 82-131== -49g


Total result: -60g

Image
Image
+ At first, I want to swap the ND side PM pedal body with Thrust sl's to cut additional 14g off but failed...

1. I followed the instruction of a WW user "mattsurf", viewtopic.php?t=148289&start=360 (on page 25)
Image
2. When I add the dust cover which should be inserted between the body and the axle, pedal does not want to spin at all..
3. Because of 2. I decided not to put dust cover but insert a o-ring to prevent water ingress, and I tightened the nut and it works.
4. But... swapping body adds almost 3mm q factor.. I Dunno why
5. Does anybody know how to deal with this? I still want the additional -14g.... :welcome:

6.79kg with Assioma Uno, 2 bottle cages, and Garimin and front light mount combo.
size: 54,
Uno 7 stem 80mm, Primeavera X light 360mm bars.
Sram Hydro R red 22 with 9100 dura ace front mech.
Token T47 external bb, Rotor Aldhu carbon 165mm 50/34 dm rings.

- It's super stiff.. I kept the wheelset, tire pressure, tires, and saddle all the same but it is definetely waaay stiffer than my Super X.
I am quited frustrated about this.. Felt IA disc felt softer than this. What the heck is it..?

- Overall build quality is actually "good". I haven't noticed any problem yet.
I heard that pre 2023 Ventums were not this good.. A.K.A "open mouldish bikes" but IMO 2023 models are far better.

- Racey Geo.. the stack height is almost 20mm lower than Super X. I wanted to use 17 degree stem but couldn't due to the lack of flexibility.

- A finicky saddle clamping system: Ritchey's one bolt mounting clamps/
I had to source 7*10mm clamp for my Tune saddle. What I need is top-bottom clamping one.

- It is future proof: Sram UDH and T47 68mm BB.. and Token Cable box system.

I'm currently running GP 5000s TR 32c (it bulges up to 34.4mm when inflated)
There's tons of clearance (YaY). at least 20mm gaps.
Ventum says this can handle 2" but it seems to me 2.1~2.2 with less knobby tire will be fine.

Sometimes, I rode 65mm deep rims (Corsa speed 25c, Pro one TLE 25c both TL setup)

Some Look compatible pedals and cleats are so slippery and they are sometimes noisy. I use dual sided velcro tapes(one for glue and the other one for velcro) to prevent these matters.
