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.

Where did you buy the mount from ? Can't find it anywhere... does it fit nicely on canary bar ?
I got it from AliExpress but I don't recommend it. Mine snapped when going over a bump.

If you have more feedback on the Lewis SLR calipers, please chime in.

Since you had Red E1 in the past, I would like to know are they better or on par with no difference in modulation feel/stopping power.

I know it's winter in the East Coast but inquiring minds want to know!!

BTW: awesome example of a 12 pound disc brake machine! I would never have fathomed this could be done.

Lots of climbing today in Shenandoah National Park. I really love the feel of the tops on the Darimo bar. It's really comfortable to hold on to.Image

I'm not sure if this is helpful to anyone, but I did a 40 mile ride in freezing weather yesterday with the new brakes and all I can say about them is that they feel the same to me as the SRAM ones. I would not know that I had new calipers on if no one told me.
I have no technical insights regarding how the brakes feel compared to the SRAM ones.

They look much better than the D1 or E1 calipers. Any experience with Hope RX4+?

Not much weight savings but they look fantastic!

This is my first time trying a 3rd party caliper. I mostly got them because of the look.

New 3D printed titanium computer mount with 3d printed adapter for my Karoo.
It does not offer any substantial weight savings over the Alpitude mount I was using previously but it allows for a very smooth transition between the bike computer and the bars.
I also like the placement of the accessory mount under the handlebars instead of under the bike computer.ImageImageImageImage

The pivot bolt and the saddle yokes are from the same person who made my Carbon AXS batteries.
He sells a bunch of weight weenie parts on Taobao in China.

Can you link the seller please? I have a friend who has a Taobao account so I'd like to look into what they have for sale.

I found these SRAM batteries, the smaller version looks interesting! No weights listed though but it looks to be half the weight of the much larger original batteries.
