Re: Any chinese road bike electronic groupset coming soon? Where are you from? r2-bike says on their website that they'll come in 2-3 months. The other big german shops have the Rival AXS derailleurs in stock.

More interesting imo would be hydraulic disc brake stuff, especially for the Gravel guys.

Magene P325 CS - First Impressions I really wanted a power meter for my bike, but did not want to pay the normal rates for the a dual-sided meter
Noticed the Magene P325CS was a dual meter option for a reasonable price, so I pulled the trigger.

I think it retails for about $450/$550 CAD, but I picked mine up for about $350 CAD.  I got a standard 53/39, with 170mm cranks.

Packaging:
It comes in a pretty box, and is well-packaged.  Left crank is packaged in a separate box within, and the crank set protectected with a custom-cut piece of packing foam.
Includes: Chainrings, Cranks, magnetic charging cable, instructions

Build:
Everything looks well-machined.  Smooth, with no burrs.  All parts fit perfectly. 
The cranks are hollowed with 3-holes, 2 of which are visible.  Anodization does not run the length of the holes, and stops about an inch in
They are a bit chunky at 775 grams.
The power meters are rechargeable, and come with a charging cable that magnetically sticks to the charging ports on either crank
There are reports of chainring flex under sprinting conditions, but I cannot comment as I swapped out the rings for 1X.
The spider LOOKs like a direct-mount SRAM 8-bolt AXS interface, but it is not.  The SRAM 8-bolt interface has one shorter spline.  This means that if you switch chainrings, you will need to take a round file to one of the splines to get it to fit on the cranks.  (I had to do this with my Stone AXS-to-5-Bolt Adapter)
Note: If you want to switch out the chainrings, you will need to get one that allows access to the drive-side charging port.

Installation:
As easy as can be.  Fits standard BB road shell width, with 24mm crank shaft. 
Slide through BB, pre-load with 10mm hex bolt, tighten left-side pinch bolts.  done

Accuracy:
Can't speak to this, as this is my first power meter.  GP Lama reviewed, and it is not as accurate as he would like.  This was also looked at by Ronald Kuba, and to a lesser degree Charles Ouimet. 
Both of them believe it is fit for purpose, unless you are at a competitive level (which I am not, and early data from the power meter backs this up - lol)
At the end of the day, I am only competing against myself.  At the very least, it will be useful in trending performance changes.

Set-up:
Connected easily to my Magene C406 using the Onelap utility, which then syncs with Strava.  No issues here
One a few rides, but so far no signal drops

Features:
The Onelap utility provides all the metrics you could ever need.
Basic things it does track are: Power, cadence, left/right balance, pedaling efficiency, torque effectiveness.
It then makes other calculations, such as Power Zones (Anaerobic, VO2 Max, etc.), Watts/kg, Training stress, intensity, normalized power, etc.

All in all, I am quite happy with it.  For the same price, I could have gotten a single refurbished 4iii or Stages crank. 
Whether it is as accurate as a pair of Assiomas is irrelevant for me.  It is accurate enough for my purposes.

Re: ZTTO 11-46 cassette 11 speed You do need a spacer for an 11speed mtb cassette on a road free hub body. For example , https://www.bike24.com/p259996.html

Re: ZTTO 11-46 cassette 11 speed You are correct in the road world, 11 speed cassettes got wider and thus a longer freehub and 10 speed cassettes would need a spacer.  In the MTB world, 11 and 12 speed HG cassettes have the large cogs pinned together and the large cogs kind of sit over the inside end of the freehub, so it packs 11 or 12 cogs in the same 8/9/10 speed freehub.  Now that road groupsets are coming with wider range cassettes it gets a bit foggy, because the 11-28 to 11-32 cassettes are road, and 11-42+ are MTB (even if they come in a road groupset), not sure about mid range like an 11-36.

Re: ZTTO 11-46 cassette 11 speed I got the 34t ZTTO one with the Alu large cogs. I felt like it was 'loose' but i did the lockring tighter and it got rid of the wobble. Maybe try another thin washer that the lockrings have on them?

Hi All,

I finally finished the build of the my bike.

I'm not totally happy with the feeling of the cable actuated hydraulics brakes because I had to swap the outer cables from the jagwire compression less for a cheap Clarks that were quite more flexible and allow me to fit them through the headset without kinking.

I will give a bit if time testing the bike and if the biting don't improve I will take it to the bike shop to have some advice.

A part from that during the short ride that I did to try all was working fine the bike rides very comfortable.

Hello there, I can fully understand your point.
Using the compressionless Jagwire cable makes a huge difference.
Last year I built a bike for my GF and was not aware of this fact and used cheap outer cables with the steel coil.
Result was an unsatisfying feeling when breaking that needed way too much force. Additionally the ZTTO brake callipers where not working well.
As a result she got an upgrade to Shimano full Hydraulic.

For my new build I went with Jagwire compressionless and made sure there were no tight curves in the routing, which may be challenging for all internal cabling trough the hanbdlebars...
In my case the routing through the Ti frame allowed for smooth bends and the resulting break feeling is very good and quite close to hydraulic disc.
How good the break power is, needs to be confirmed during longer rides.



But don't write off the cable actuated brakes without trying compressionless...

Shifters: SRAM HRD Rival AXS
Derailleur: SRAM GX AXS
Bottom Bracket: SRAM DUB BB386 Wide Road PressFit
Crankset: SRAM Rival 1 AXS Wide - 170mm 40t chainring
Chain: SRAM GX Eagle

Tires: WTB Venture 700x40
Barfly spoon mount for bike computer

Waiting for Rockshox Reverb AXS XPLR 75mm dropper to be available to replace the included seat post.

Quick build to replace my son's old college commuter that turned into a drop bar gravel conversion.
It went pretty smooth, there isn't a lot of room in the handlebar for cables and we only had the two.  I can imagine it might be rough to get shifter cables in there as well.  Otherwise it looks really nice with nearly no visible cables.
Used supplied headset bearings, they were pretty good.  The cover and spacers are an oddly fitting alloy two piece design.  Carbon would have looked nicer but it is fine.
Soooo many mounts on this frame - Three bottle cages, bolt-on bento box, accessory mounts on the fork, and full fender mount points front and rear.  It looks well thought out, I'm jealous.

Kinda crap picture, it was taken for him while waiting for him to bring over the old bike to move pedals.  If anyone is interested I'll take more (better) pictures the next time we ride or whenever the dropper arrives, whichever comes first...

Can you add the pictures of the build?

I'm rebuilding mine again as I had to change the brake outer cables to improve the braking.

Unfortunately, I didn't take any during the build.  This install was really minimal with only the brake hoses in the frame so I didn't think it would be that interesting.  If you have a particular question let me know.

General build advice for this frame and others with near full integrated wiring is to run all the housing/hoses long and get the front end situated first.  All the tricky bits are at the front where you don't have the luxury of leaving a little cable length. 

For example, I needed a wire hanger to run the brake hose through the integrated bar and stem combo since there is a lip on the ports that my magnetic guide kept getting stuck:



Leaving the front brake hose long allowed me to run the cable without having to be in an awkward position of fully mounting complicating the rear brake hose run.  The fork has a cable channel so no fishing required. 
If you have a magnetic internal cable routing tool set the frame cable runs are simple and unobstructed.  There is also a door under the bottom bracket if you need a midpoint, dropper, or front derailleur cable access.

I could also see the housing bend from the stem headed into the spacers and head tube being hard on cables, I would consider the external cable mount if you have a 1x.

Re: Velobuild GF-002 Frame came in yesterday. Starting the build today, everything so far looks really good. No pain build up on connection points and an etap setup should be relatively smooth.

Re: Velobuild GF-002 Finished the build.

Sram etap 1x setup 42t by 10-44t.
Cable routing was straightforward, went with the integrated stem and it was a breeze.
Really happy with the paint and finish work. Frame quality beat expectation.
