Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
I already use some Stone chainrings on my 1x Gravel bike. My plan was to create a light crankset with a Sigeyi PM and 50-34 Stone chainrings. Following combinations: Zrace RX4 - Sigeyi PM - Stone 50-34 chainrings: 859g Racework N1 Carbon - Sigeyi PM - Stone 50-34 chainrings: 632g Original 105 Di2 with Stages PM: 777g The problem I discovered on my new Roadbike project is that the Sigeyi PM inner diameter on the drive side does rub against the T47 BB area of the frame... so had to go back to the original Shimano 105 crankset combined with my old Stages PM. So 145g heavier than with the carbon crankset. I have installed the Zrace N1 Carbon crankset with a single 44T chainring on my Gravel bike for testing. So far I could not see the weakness on the non drive side that Jonathan reported... Will take a while until I have a chance to ride the bike outside to test if the crank is stable or not... Here some pictures of the three crankset combinations with weight. Shimano 105 / Di2  Racework N1 Carbon with Sigeyi PM  Zrace RX4 with Sigeyi PM  BR Chris January 15, 2023, 02:32:50 PM |

Re: Advice on fake frames
Well I was unsure if I should post anything regarding my new racebike project since it is a copy of a well known brand... I was curious enough to place an order and build up the bike after checking the inside of the frame with a camera and all looked good. Seller was the mentioned Rocking cycling store, I ordered the frame on October 19th and it arrived just before Christmas. The paint quality leaves room for improvement but the rest of the frame, seat mast and handlebar look good. Only the break areas and the handlebar spacers needed some manual work with file and sandpaper... Here a picture of the finished bike with 105 Di2, Elite Edge wheels GP5000 28mm: Total weight 7.6kg. First ride was excellent, the bike accelerates fast and holds speed well. Position on the bike is comfortable.  Honestly speaking, if I would have found a similar frame design from a Chinese manufacturer like Seraph or Winspace I would chosen one of their frames instead. But I always liked the design of this particular frame so took the risk to give it a try... if it does not work out it will end up as my indoor bike  BR Chris January 15, 2023, 03:01:49 PM |

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
Received RXL SL handlebar from Amazon today and quickly got to install it. First off, the internal cabling is a joke - you get to hide all off about 8 inches or less cable coverage and the holes are rough. I had to file every inlet/outlet before I could put cables thru. But that's not the major issue, after installing I found that these are overly flexible. The ones that came with my VB frame are exponentially better. There is not even a contest. These go for $45-50 on Amazon and & $40 on A-ex. These look copies of a Toseek model on A-ex. Wonder if Toseek would have been a better choice. Any how, You have been warned.

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
I have been wanting some accents on otherwise plain looking bike of me. Not Ali-ex but I found these tiny flag stickers on etsy - https://www.etsy.com/listing/623422788/american-flag-united-states-flag-usa They have all other flags too. January 17, 2023, 03:46:43 PM |

Re: Gravel Bars (Carbon vs Alloy) (Flared vs Regular)
I might add, I've been a die hard roady for 45+ years. Never in my life would I have thought that I might use any bar other than a regular drop bar. Unfortunately pain is a motivator to try something new, otherwise I would still be using regular drop bars. From my perspective, I have found that flared bars give a wider, more stable position in the drops, which comes in handy on rough terrain and when descending. On my 29er hardtail, with flared drop bars, I have been able to coast at full speed down 8+% grade, very rough/washboarded forest roads. (Over time I rode these descents on flat bars, regular drop bars, full rigid bikes, full suspension bike, with flat bars.) My fastest descent times are on my 29er hardtail with flared dropper bars. My FS ride with flat bars is the next fastest. In the past, my buddies used to be significantly faster than me on these descents. Last year, they were asking how I had become so much faster. I believe that is is the stability of the flared bars and being able to tuck on the drops in a more wider more comfortable aero position than either flat bars or regular drop bars.

Re: Onirii carbon cranks
Yeah they look, spin and feel great when pedaling..... Thanks for the info, strangely my Rival 1 crankset is a 24mm spindle, so these should fit perfectly but I will dble check. My Rival 1 crank with chainset is 920g, so this'd be a big weight saving. AUD $200 to save 500g seems like a worthy investment. Interesting on the Shimano crank arm, I just sold a DA stages PM and moved to speedplay PM.... Almost a shame I can't get this raceworks crank with a PM built in..... but then I'd need a bigger spending budget. Thanks again. January 23, 2023, 01:06:00 PM |

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
I got the light in the mail yesterday. 11 days! Seems pretty nice for $35! It is obnoxiously bright. Definitely isn't 5200Lumens, but its way brighter than the pair of 1000s (labeled) i've been using for MTB night riding. The LED reflectors focus the beam nicely. There is a center spot focus reflector/LED and 2 reflectors/LEDs on either side that seem more flood oriented. You can run it with just the center LED, only the outer 4 LEDs or all of them on. There is also a flashing mode that uses all the LEDs, which is probably so intense that it could cause an epileptic seizure. The mounts seem pretty sturdy and I like that they are fold away clamps so mounting the light is a 2 minute job. You can slide them across so they'll work with tons of options. I haven't had a chance to do an extended ride with it to test battery life. It supposedly will run 2.5 hours on the highest setting and 10hours on the lowest. If it poops out mid ride, an hour in, I will update on that. Here's a photo of the light mounted. January 25, 2023, 12:50:24 PM |

2023 VeloBuild CX-002 Cyclocross Frame
This should probably go under the Gravel/CX section, but the road bike section is more active. And I suppose you could use this frame for all-road versatility. Size 54/M Matte Black Includes rubber seatpost dust cover and, to my surprise, some sort of 3M chrome chainstay protector to prevent scuffs. I suppose the assumption with cyclocross is there is a higher chance of dropped chains. Pretty thoughtful. The frame is pretty chunky. Weight includes hangers, bottle cage bolts, and plastic grommets. BB area, headtube, and caliper mounts look good. Gonna run SRAM eTap plus a separate bar/stem combo via FSA no69 headset system...per usual. January 27, 2023, 06:04:38 PM |
