Re: Speeder SC-R48 I exchanges emails with Longteng bikes about their superlight LTK036. The weight of size 50cm is 780+/-30g in carbon finish . And each larger size will be about 30g heavier. The price of the frame is $420 usd/set (Frame+Fork) in carbon clear coat or matte finish .  I will add pictures. This is the weight for a size 55.

Re: Speeder SC-R48 Okay, so some interesting new discoveries:

There's this fully integrated SLC 2.0 using the Winspace Zero cockpit and this other example, both with the external brake holes still in place. I'm unsure if a hole had to be punched in the fork steerer or if the stock fork comes with provisions for external and internal routing to begin with.

Looking back at that fully integrated Adris Soar, the cockpit looked more like the Speeder SC-RH02 than the Winspace Zero. Where it gets interesting is that there may be more players in the Speeder/Winspace/Gotobike circle than I originally thought. The SC-RH02 cockpit looks the same as the Adapt AHD-01 and Edge Design HB-20 while the SC-R49D frame looks the same as the Adapt FM49-DB and Edge Design Aeolus.

Adapt also has frames that I couldn't find anywhere else like the AT-B01. They seem like a legit OEM supplier too as the Olympia Leader seems to be a rebrand of the FM08-DB frame.

And since Adapt states that the AHD-01 accepts fully integrated mechanical groupsets, the Speeder SC-R49D & SC-RH02 combo should be compatible too. All we need now is for Speeder to update the SC-R48D to work with that cockpit and we should be good.

Why wouldn't the manufacturer have pictures of their own bikes?

Possibly because they never expected a group of cheap bike nerds to convene online for the sole purpose of figuring out who the OEM of a specific frame is  ;D

Re: Speeder SC-R48 So I've finally completed the build of the frame I bought from @trilobites

I'm switching from a Factor o2 2018 RB with 8050 Di2 and so far after a few hundred k's the main difference is the stiffness in between both frame's rear triangle has the o2 was much more lively and felt alive when climbing out of the saddle however it looks like the power delivery is a bit better on the speeder.

I will report back after a month or two on the bike for a clear review.

Re: Speeder Cycling SC-R55D Just about ready to take on a maiden (outside) voyage!  Still playing with painting the bottle cages the same as the frame. There’s some small things to add still, but it’s currently 16.0 lbs, or something.something kg.

Re: Speeder Cycling SC-R55D I only did a quick ride around the block with it, but it feels damn good. Can't wait to do a real ride with it.

Speeder did the paint job.

Re: Leese carbon crankset The instructions that come with these cranks are pretty poor.

Cybrei’s instructions, on the other hand, are excellent. They advise using vernier calipers to measure your bottom bracket shell width, provide a detailed list of bottom bracket standards, and show the corresponding spacers or shims required. Since many of these cranks look very similar, clear and specific instructions like these are really helpful — and they’re readily available on the Cybrei website in English. The attached Cybrei PDF in Chinese has the BB spacing table.
https://www.cybrei.com/wp-content/uploads/2024/05/%E6%9B%B2%E6%9F%84%E7%94%A8%E6%88%B7%E6%89%8B%E5%86%8C.pdf

I’ll also measure from the centre of the bottle cage boss to the inside of each crank arm to ensure the distances are equal. This can help identify alignment issues in some cases.

I’m using the DFS carbon crank, and they basically told me to follow Cybrei’s instructions, since they don’t supply their own as the have not managed to put on together yet!. I also contacted Passquest/Sprill, and they just sent me their standard instruction sheet again.

Peter's are for sure. I was in contact with him a month ago after I bought a frame from him and some wheels. I asked him to message me when they are available. I want to use a 1x with the R01 I bought.

165mm both 29mm DUB aluminum spindle and 24mm titanium spindle options would be available in May, orders accepted for now. And the chainrings too.
Chainrings spec.
Double rings:50-34/52-36/53-39/54-40
Single ring: 46/48/50/52/54/56/58

Next sizes would be 170mm and 155mm cranksets. We are making carbon sprider as well.
