52cm Specialized Tarmac SL8 Onyx Blue - 6.14kg

[mike]

i cracked my gelu k3 saddle. was super light but not durable

[Aryeh]

New Gelu E3 saddle arrived today.
It is 61g instead of the quoted 55g.
I will be testing it to potentially replace my 80g Berk Lupina that I've ridden for the last few years.

I have the E3 saddle on two bikes. I've also had, and broken, quite a lot of Berk Lupinas. Comfort is personal of course, but there is no comparison between the two in terms of quality IMO. The Gelu is streets ahead of the Berk. I find the Gelu very comfortable, but it has noticeably less flex than the Lupina.

I've only ridden it on the trainer so far. It feels comfortable but a bit more slippery than the Lupina.

Darimo seatpost finally arrived today after nearly 3 months.
93g for my 250mm straight 3K matt model.

Next up,
Slightly lighter front rotor from tipartstitanium, Carbon fiber cased AXS batteries from Taobao, Darimo clone computer mount from AliExpress.

[Aryeh]

New computer mount and rotor have arrived.
The rotor is 10g lighter than Galfer. The computer mount is 12g lighter than the one I was using previously.
Bike is now at 6.19kg according to Kern and 6.175 according to my fish scale. I assume the Kern is correct.
I switched from the Challenge tires to the GP5000TT and they came in quite about 40g heavier than the Challenge tires for the pair, but I rode them outside for the first time yesterday and I got multiple PRs and they feel noticeably faster so I will keep them on despite the weight penalty.

Do you mind sharing a pic with the TT mounted so I get an idea on how the look? Black vs white walls
Besides how do they measure vs the RS?
Thanks

The Challenge tires were 27mm and I don't remember what they measured. The 28mm TTs measure 31.5mm.

They do blow up quite a bit
I wonder if a 25F 28R would be the way to go

I think it is. I ordered a 25mm for the front. The rims are 30mm ext. so I'm hoping a 25mm, assuming it inflates to 27-28mm will work better with the 105 rule, while also saving 40g. (My 28mm tires came in at 260g each).

28mm wide at 80psi. 211g vs 258g for the 28.
The bike is now at 6.165 with 40ml of sealant in each tire.

@aryeh are you using an 300mm seatpost? if so, which is the maximum seat height on your 52 frame?

That’s quite a saving
You have 24IW on your Hyper50, don’t you?
If so I’m wondering if with mine which are 21IW I might try both and see how they come up
