Re: Systemsix frame I just received a quote for my measurements (height: 183 cm, inner leg: 88.5 cm):

"SC-R49D frame + fork + seatpost + handlebar: US$780/set
Thru axles: US$20/set
NO.55R headset: US$30/set
Shipping cost: US$120
PayPal fee: US$45

The total is US$995.

I would recommend the size 50cm, reach 397mm."

The only thing that is holding me back from pulling the trigger is a lack of information I can find on the frame, e.g. reviews / pictures.

Is Speeder Cycling a reputable brand? And do we have people here that have experience with that particular frame?

Re: Systemsix frame I just preemptively ordered my group set (Ltwoo ER9) and wheels (Elite wheels Pro 55mm). After wrapping up a couple of final questions for Speeder, it seems like I have a beautiful build to do within the next couple of months.

Thank you all for the help. I will surely post pictures of the parts and complete bike.

Re: Systemsix frame I reached out to Justin last week to ask about the shipment. He responded the frame would be ready this week.

Speeder Cycling SC-R49D Hi all, this is a first time build for me, which I just finished building. This will be a first introductory post to describe my experience. After spending numerous hours (including here on Chinertown) I decided on which bike I would build with the following primary parts:

Speeder SC-R49D (because of the aggressive geometry, and the aesthetics of the wheels "cutting" in the frame)
ER9 (as an entry level priced electronic groupset /  12 speed)
Elitewheels Pro 55mm disc (had good experience with rim wheels before / are friendly priced)
105 crankset
+ 105 power meter (comes from previous bike)

Good:
- the bike is exactly what I expected in to be in terms of aesthetics
- seemingly built well (although I will return here after I had plenty of km's on it)
- reasonably priced (1000 USD for frame, handlebar, headset, fork, seatpost and shipping)
- Speeder is OEM for Winspace
- standard position is VERY aggressive (which is exactly what I was looking for)

Medium:
- sticker on the box mentioned the frame in another size (thankfully the actual frame was correct)
- the communication was alright, although he could have been a bit more transparent in terms of producing / shipping times (only mentioned AFTER purchasing the frame: 3 months)

Bad:
- both headset bearings had a lot of play, which stressed me out as I thought I had a faulty frame. Thankfully, after finding one of patliean1 posts on headset play, I reduced it to almost zero with adding a couple of layers of tape in the socket of the bearings.

Open issue:
Now that the bike is fully built, I wanted to take it on a couple of rides. However, I can already feel it pedals very heavy and even backpedaling feels heavy as well. Both wheels spin very freely, and the crank set without chain also somewhat freely (my old bike was better in this regard).  I just tried pedaling back, and it seems like the cassette does not want to spin, as the chain will just lose tension and curl up.

Does anyone know how to resolve this issue? Thanks!

Re: Speeder Cycling SC-R49D It indeed was you Joegal! Thank you for the suggestion.

No, I did not weigh the parts separately. The total build comes down to 7.8 kg (as seen in the picture). And to my calculations, it does mean the parts (as least of a sum from Speeder Cycling) are close / identical to their presented weight.

Re: Speeder Cycling SC-R49D Ltwoo groupset
I just finished my first ride where I did not have issues with the groupset. For anyone with an ERX / ER9 groupset, I suggest you add some ductape between the connectors for both derailleurs. After I did this, the groupset has been incredible, and is a dream to work with. Especially for that price (~500 eur).

The only downside now is how my hands fall into the shifters. This is obviously a personal topic, as the shifters might fit you like a glove, but it feels incredibly awkward, as if my hands are simply too large. I will play around with the shifter position on the handlebar, but if that does not resolve the issue, I might take the route of 3d printing a mold that perfectly fits my hand (on top of the shifter). Has anyone thought about this before?

Speeder frame
This frame is asking for speed, and when getting in the aero hoods position, it is incredible how easy it is able to hold high speeds. 62 kmphs was no problem on an extended piece of flat road.

The frame feels stable and stiff, and regardless of how much power I push through the pedals it remains composed.

Finally, I have had an enormous amount of compliments of people while riding / cleaning the bike, and I have to wholeheartedly agree with them that it looks absolutely stunning.

Re: LTWOO ER9 & ERX - Electronic groepsets I am not trying to add negative publicity, rather add a simple piece of truth, and a way to deal with it. Again, now that I used the tape, the groupset is working like magic.

Re: LTWOO ER9 & ERX - Electronic groepsets
I am having issues with my Erx- randomly working/not working and being slow to respond (it's been very wet here) while working fine with the app but not the brifters (which have new batteries in them and the system is fully charged).  Would you be able to describe in more detail what you did with the duct tape? Did you wrap a small piece around where it plugs into the mech or ?? I'm not quite sure how to follow your suggestion and I would LOVE to have a working set!

Step 1:
Disconnect the cables from both derailleurs
Step 2:
Be absolutely sure there is no moisture in the cable or port on the derailleurs. Thoroughly inspect with a flashlight, and let it dry overnight if you want to be absolutely sure.
Step 3:
Rear derailleur: create a strip of ductape (2cm x 5cm), connect the cable and wrap it around the derailleur + cable to make a tight fit. Press down on the ductape to ensure no moisture will get in. Make sure the tape surpasses the "cup" (poor design) which fits the cable.
Front derailleur: unmount the whole unit so you have better access to the port. And repeat the process for the FD. This one of more finicky, but just try to make sure you have a reasonable connection. The FD is less likely to ingress water as the port is downward facing, whereas the RD is essentially a convex shape, waiting to pick up rain.
Step 4:
Ride!

Re: LTWOO ER9 & ERX - Electronic groepsets My rear derailleur stopped working as of a couple of days ago. I was starting a casual ride, and out of nowhere it stopped shifting. The motor makes a sound but no shifting happens. FD works totally fine.

The template below was shared when talking to customer service.
