Re: Best TPU tube brand
No, I have not. Are these the latest iteration? I noticed they released „allroad“ tubes at around 45g for tires up to 34mm or bigger I think? But those still have plastic valve stems. I believe it but I am not sure. There is also Geoid brand. August 02, 2024, 06:55:40 AM |

Re: Spcycle New Mold SP-R088 Carbon Road Frame
This build has taken me a bit longer mainly due to fit issues with the ER9 battery, but I finally solved the issue! I was almost about to give up and just build this bike mechanical or save up and get a Wheeltop EDS TX, but all my ideas pop-up in my head when I wake up in the morning!  Disregard anything I've written previously, these are the definitive steps to use the ER9/X on the r088 and possibly other sl8 clones! After examining the whole assembly, I found the full ER9 battery holder (with cover) can snugly fit into the seat tube, but in order to get it out, I tied 2 pieces of ribbon string to both ends of the battery holder. You can then easily pull it out for maintenance and/or battery replacement. The seat post will still need be cut, but no drilling is necessary for the Di2 clamp holder and you won't need to use it (only for the ER9/X). Though make sure to not lose it, replacement Di2 holders on AliEx are like $20 USD! The ER9 battery holder diameter is just wide enough that it won't shake around the seat tube. Though the fit is so tight there's no way to wrap it in either bubble wrap or even thin plastic wrap. For both ER9 and Di2, I would definitely install the battery cabling first before installing the bottom bracket. I opted not to use the hole behind the FD cover. Routing the battery cable that way makes it extremely difficult (though not impossible) to get the excess cabling into the seat tube or else it will get in the way of the battery holder (the fit is very tight). You want to get all the excess cabling below the FD hanger mount in the seat tube. For ease of installation, I instead used the lower hole that could be used for mechanical. This is an option that I'm only aware of with the R088 and might not be available on the other SL8 clones/copies. Anyways, this frame design really seems like a big f**k you to Shimano. Also the way the RD hole exits through the lower chain stay seems more like an afterthought. I definitely think this frame was build with full wireless in mind. Hopefully I can complete this build soon, since I was able to figure out this problem! January 06, 2025, 11:36:14 AM |

Re: Spcycle New Mold SP-R088 Carbon Road Frame
After solving the ER9 battery fit issue, the overall build is going smoothly. I still need to swap over the ER9 shifters from my other frameset. I'll probably run a few stem spacers until I get used to the fit, though I'll most likely slam the stem. I put a rubber seat post gasket to show where the seat post would be without an ER9 or Di2 battery installed. On a full wireless or regular mechanical setup, it will go down all the way. If running SRAM AXS or Wheeltop, you can definitely skip the seat post cutting and positioning of the battery cables. I included shots of the chain stay and fork tire spacing. 32c tires look like they'll fit, but will definitely be snug in the rear. January 06, 2025, 03:07:04 PM |

Re: Spcycle New Mold SP-R088 Carbon Road Frame
R088 is done. 7.2kg on my heavier 45mm depth carbon wheelset and 6.9kg on my 1100g 30mm depth climbing wheelset. This is with pedals, power meter, bottle cages and built-in computer mount with 34cm drop bars. Unfortunately I can't ride it due to multiple fires in the Los Angeles, USA area. The air quality right now is s**t...smells like a smokey camp fire. I'll post photos tomorrow. I had to clear out my yard of debris and ash! FYI - I'm about 173cm and I went with a 52cm frameset.

Re: Spcycle New Mold SP-R088 Carbon Road Frame
Photos of the build! As I mentioned previously, I can't ride the bike right now due to major fires in my area, so I can't comment on ride quality until things clear up. I've included close-ups of the UD glossy raw finish. In-person it looks like black marbling, similar to a bowling ball with similar finish! Also I pre-applied clear protection decals to certain areas of the frame. Some of the straight lines in the finish are from the protection decaling. January 09, 2025, 01:25:24 PM |

Re: Spcycle New Mold SP-R088 Carbon Road Frame
Did you have any problems while setting up the electronic shifters? Some people talked about the problem of poor moisture protection in er9, maybe it has been fixed now, what do you think? I have 2 ER9 groupsets and 1 EGR groupset. No problems with water ingress, but I rarely ride in the rain and I apply liquid tape/rubber cement and dielectric grease to all the battery ports.

Re: Spcycle New Mold SP-R088 Carbon Road Frame
Quick ride feedback. I only did a local neighborhood run to fine tune the electronic shifting and to bed the brake pads. The air quality in my area has slightly cleared up from the Los Angeles fires, but I don't see myself doing a hard ride just yet! Overall the frame feels stable. It holds power well, I didn't feel like it was a struggle climbing with the frame. If anything, the bike can be pushed and respond well to the rider. My heavier wheelset didn't even feel heavy, I'm guessing my climbing wheels will feel great on the R088. I've yet to push it through the fast flats, but I think it'll be fine. Also running 34cm drop bars on this bike feels good. Didn't feel narrow and steering was precise. Oh yeah, last night I re-did the brake lines and swapped out the bar tape (old tape), I think I had the cable orientation set the wrong way. I fixed it and had just enough brake hose to fit the bars. Any more adjustments will require a new rear brake cable! January 10, 2025, 03:22:18 PM |

Re: Spcycle New Mold SP-R088 Carbon Road Frame
Today I ordered this frame in matte color for 520 usd. They wrote that it will be sent on January 18, probably it will come to me next month. Most my frames are 49cm to 52cm, so I don't really notice that softness taller riders might experience. Though in regards to power transfer, my aero frame can put down more power to the pedals, though with a weight penalty. The R088 definitely seems to falls somewhere in the middle.

Re: Spcycle New Mold SP-R088 Carbon Road Frame
I was finally able to stretch the legs of the R088 and did an early morning ride before the pollution levels of the Los Angeles fires became worst as the sun came out. I took it on both some long flat stretches and my local climb areas. It's relatively lightweight and I felt like there was good power transfer. On the flats, it accelerated smoothly while holding speed easily. On the climbs, I could go out of saddle and the frame responded well to rocking the bike back-n-forth. Handling is very good as well, I didn't even notice any toe overlap and steering felt precise without being overly twitchy. My only issue is that my other wheelset with 25c tires looks a bit awkward. For climbing I tend to prefer narrower tires. Aesthetically it looks best with a 28c tire or bigger. Overall it's a very well-balanced frameset. I think I could comfortably recommend it.

Re: Spcycle New Mold SP-R088 Carbon Road Frame
it's a clear finish, not a paint job. They usually let you choose between glossy or matte. the glossy one lets you see all the grain of the carbon. the matte one hides it a bit January 18, 2025, 01:52:51 AM |
