Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc! tbh many of the cranks I see on Aliexpress would scare the crap out of me. They look like bad accidents waiting to happen.

Re: Lightest FSA ACR-Compatible 2-Piece 36/38 Aero Cockpit i just ordered Mosso ST08 + kocevlo sl 150g 380mm

im building a bike off tt-x38, n am looking for alu stem so i can mount my controltech falcon mini stem-mount ver.

upon scouring aliEx, i narrowed down to 2 stems:
- mosso st08
- kocevlo <no model num> https://a.aliexpress.com/_oENMzN9

Re: LEXON Road Carbon Crankset I finally managed to fix the chain line issue on my setup. My BB is 90.5mm (BBRight). As others have pointed out with chainring issues, the same problem exists with the spider. The machining quality is poor - some tabs on the spider are 3.4mm thick, while others are 3.6mm. The spacers included are also the cheapest imaginable, and their thickness is inconsistent (not 1.5mm but 1.4mm or 1.6mm instead). I think the chain line problem comes from the spider’s incorrect depth.

I’m using Ultegra 11-speed, and to resolve the chain line issue, I had to add 3mm spacers to the drive side. However, this left no room for preload adjustment, and tightening the crank bolt added extra stress on the bearings. Additionally, with the 3mm spacers, the crank arms were no longer centered relative to the rear wheel. I figured that if I used 1.5mm spacers on the non-drive side and adjusted the preload ring by ~1.5mm, I could center the crank arms. While this helped, the chain line worsened, as the spider was pushing the chain too far in, causing it to rub against the inner plate of the front derailleur.

Here I realized the spider itself was the issue. After searching online, I found a replacement spider from Stone with similar dimensions but slightly less depth. I decided to take a chance and ordered it, and thankfully, it worked. The new spider had a ~1.5mm shallower depth, reducing the need for 3mm spacers to just 1.5mm, and I could finally use the preload ring. The chainring tabs on the Stone spider were also properly machined, with a uniform thickness of 3.5mm, similar to Shimano’s. I slightly adjusted front derailleur and everything looks okay for now, however I haven’t been able to properly test it outside yet, as it’s winter here.

Initially, I wanted to return the crankset. The seller contacted me, begging not to return it through AliExpress, as he’d lose money and the crankset would just be recycled somewhere at AliExpress's warehouse. He promised to cover all costs if I shipped it directly back to China. I asked him if he can provide any solutions and decided to give him a chance, but after two weeks of vague promises and no real solutions, I found my own fix and asked him to compensate me for the replacement spider. At first, he claimed it was too expensive and suggested splitting the cost 50/50, but eventually, he agreed to cover the full amount. However, it’s been nearly two weeks since then, and I still haven’t received any refund. Now I'm being simply ignored.

So, I DO NOT RECOMMEND buying this crankset unless you’re confident you can handle the issues yourself. The crank arms and spindle look good, the rest is bad, and if anything breaks, don’t expect much in terms of support. While I’ll probably keep the crankset, I’m still unsure about its reliability since I haven't tested it outside.

Re: LEXON Road Carbon Crankset Interesting. One thing I don’t quite understand yet fully: if the elilee spindle is the same length or even longer: why aren’t there any complaints? (At least as far as I can tell from regular visits to the weightweenie thread).

Re: LEXON Road Carbon Crankset Yeah I know. 105 vs GRX is 5 mm total, so 2.5 mm each side

Re: LEXON Road Carbon Crankset PSA: Check your NDS crank bolt torque

I took my newly rebuilt bike out for the first proper shakedown ride today, previously I had only done a few laps of the block and a fit session on the trainer.

After some sprint efforts, I noticed what at first felt like a loose cleat - the left shoe somehow felt like it had too much float. But I could unclip and clip in again just fine, so I continued. When I got home I realized that the NDS crank arm was coming loose from the spindle! Had I continued much further, the crank arm would likely have come off completely.

I have the 29mm aluminium spindle version with the black crank arms (no big Lexon graphic), and the NDS crank arm came attached to the spindle out of the box. I torqued the DS crank arm properly when I installed the crankset, but I naively assumed that the factory would have attached the NDS crank arm to spec, and so I didn't verify that during assembly.

I have now torqued both sides properly, and I will do a few more shakedown rides before I take on anything serious. I'll report back here if anything else happens.

For reference, my bike uses a T47 bottom bracket with internal bearings. On the initial installation I used a 3mm spacers on the DS (as per the SRAM DUB spec for non-wide road crankset), but I replaced this with a 2mm this time, mainly because the crank arms seemed to extend a touch further out on the DS compared to the NDS (by the inaccurate method of judging distance to the chainstays).

Re: Xiamen Carbon Speed 10 years anniversary special promotion
Im saying this because I've run cfd simulations on various rim shapes with various tyre sizes. 105 just has no meaning

That great that you disproved a BS 25yo wind tunnel test with an even more BS CFD analysis.


I actually skip wind tunnel testing and CFD analysis, I acquire a rim profile in a .jpg file format and scanning with my eyes I am able to calculate the aero performance of a particular tire-rim transition with a 100% margin of error
