Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
It's great to see 48-32 options coming to ali. When I needed gravel rings last year there wasn't a single 48-32 on there, it went straight from compact to 46-30

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: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
i just joined the community and this is my first post. i've found this forum helpful in finding gravel bike parts on Aliexpress, and wanted to share my thoughts on a couple of items I've bought recently. Paul Components "Boxcar" stem - Purchased from "Shop1102602987" but can't find them now. URL: https://www.aliexpress.us/item/3256805641142650.html Review: 0/10. Junk. Do not buy. Details: I bought both the 90mm / 0 deg and 90mm 15 deg versions. When installing the 0 degree version, using a torque wrench set to Paul Comp's recommended setting, the clamp bolts all stripped out suddenly. I reported this to Aliexpress and they refunded my money in full. I haven't tried to install the 15 deg version and won't be; I think the aluminum used for this stem is poor quality, and I don't want to take the risk that the clamp could fail suddenly while riding. Redshift "Shockstop" stem URL: https://www.aliexpress.com/item/3256805944907424.html Review: 4/10. Arrived damaged. Details: The stem arrived with obvious damage/deformation to the pivot bolt consistent with someone ham-fisting an allen key tool. I complained to Aliexpress and they refunded half of the purchase price. It came with the elastomer inserts (with two installed). I reached out to Redshift for a replacement pivot bolt and they explained that they can't replace this bolt as it should never be removed from the stem or adjusted, and damage to it will wreck the stem. As a result, I'm not sure if I will try it on my bike or not. Ingrid RD-1 Derailleur - Bought from the F1Z BIKE SHOP store; it's saved on my mobile app but can't be found on their website. URL:  Review: 8/10 good stuff. Would recommend. Details: I bought two of these, one in long cage and one in short. I mounted the long cage on my gravel bike, with an 11-42 cassette and Sensah SRX shifting. It worked great right out of the box. Shifts accurately and cleanly across the cassette with no issues. I'm really happy with it and have been putting in miles on it. Hopefully it continues to function well into the future. Along with it, I also bought extra cages, pulleys, and different shifting system adapters. Just in case something breaks or I want to change it up. Ingrid Road Crankset CRS-R2 - Bought from the F1Z BIKE SHOP store; it's saved on my mobile app but can't be found on their website. URL: Review: 6/10. Very difficult install, but once installed, working well. Details: The spindle was out of spec; it's supposed to be 30mm but was closer to 30.5mm. It wouldn't fit into the appropriate BB30 cups. I had to spend hours carefully sanding the spindle down to get it to the correct diameter. The Q-factor of these cranks is very low, so I also struggled to get the spacing right and not have the crank arms hit the chain stays. There's very little room to mess with the spacing since you have to ensure the crank arms engage fully and tightly with the spindle. I ended up taking it to a bike shop, who added an additional .5mm spacer on each side, and now it clears. On one hand, I'd be leery of recommending this crankset to anyone given the spindle issues. On the other, once installed, it's working well and looks great with the matching rear derailleur. Make sure you buy the 110bcd adapter spider; the only chainring size available on Aliexpress is the 48T that comes with this crank. If you want any other size, you'll need to buy it from Ingrid at around $150 each; the spider allows you to use normal 110 bcd / 5-bolt chainrings that cost much less. All-in-all, I would not recommend this crankset unless someone really wants the look and is ready to deal with potentially very difficult install process. that's all for now. I have more items to review, including the Paul Comp seatpost knockoff, POC helmet, various lights, and other bits. hope this is helpful! December 05, 2023, 10:19:56 AM |

Re: TFSA JH-15 and JH-10 - lightweight and aero disc frames
The JH-15 is really nice, except for that super low stack: 540 in size 54. That is just too damn aggressive for the average Fred (i.e. Me). My custom titanium has 60 mm taller stack than that

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
The Temai choice store which I believe is probably stocked by the Sensah official store is now offering Team Pro shifters with a Shimano 105 R7000 RD and Empire FD. I wonder if Sensah just gave up on doing a Shimano compatible RD? December 08, 2023, 12:39:00 AM |

Re: LTWOO ER9 & ERX - Electronic groepsets
When I saw that tracevelo was having was having water ingress issues with the gravel groupset I lost all faith in them fixing this. If wheeltop group is good I'll buy that, they say it's rated for ip67.

Re: Onirii One
I took the plunge and ordered the fully integrated Onirii One frameset. I'm guessing it will not arrive until the new year but I'll do my best to share pictures/info/weights when I receive it! Hoping to build it up into something nice by the end of january

Re: LTWOO ER9 & ERX - Electronic groepsets
Step 1: Can't you use some dielectric grease? It amazes me how people keep defending Ltwoo and these groupsets with all these problems... It's not like we're talking about a 125USD Sensah mechanical groupset... It's like buying a frame, seeing it has a crack when it arrives and saying: "I'll just put some epoxy on there and ride it, it's the cost of being an early-adopter" December 12, 2023, 05:47:54 AM |

Re: Another Seaboard GR02
My frame arrived yesterday - exactly one month to California. It looks great - I love the orange, especially in the sun. The paint is really good, only a couple of very minor blemished (a couple flecks of dust, a little bit light on the inside of the dropouts) but overall very smooth and even. The welds look nice too. My XL/56 frame weighs 1976 g, including the headset, axle, and bottle cage bolts. The fork is 501 g including the axle. This is only about 320 g heavier than my Carbonda CFR707, although that included bolts for all of the mount holes. (The Seaboard only has bolts in the two bottle cage mounts on the inside of the triangle.) It will take me a while to build it up given all that's going on this time of year but I will post pictures when I do. It's a budget build with parts I had and cheap eBay and AliExpress finds.
