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.htmlReview: 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.htmlReview: 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!
