Re: Titanium Gravel bike: PYTitans build thread
After 2600km the bike is still going strong. The only modification I am considering is replacing the Zrace RX4 crankset with the Racework N1 carbon crankset. The DUB Bottombracket starts to get noisy again, it took me already some time to get it right when I built the bike. A standard BSA with 24mm spindle may be the better option due to the increased bearing size?   Here some pictures from last week Nova Eroica Switzerland, where the bike was really put to the test on some technical downhill sections. The Juintech F1 Hydromechhanical discs did well, even they were very hot at the end of the descent. BR Chris June 25, 2023, 08:34:55 AM |

Re: Which chains is everyone using?
For me a mix of different manufacturers: Original Shimano 12 speed that came with new 105 Di2 / Set included the Dura Ace chain for some reason... sometimes you get lucky  YBN - So far the best experience also looking at the quick links but can be pricy at times SUMC - For cheaper builds and commuter bikes The Chain is one side of the equation, lube is the other important topic for me: - Changed all bikes to wax based drip solution - Proper removal of factory lube is most important: 1. Clean in white spirit 2. Citrus chain degreaser 3. Rinse with water 4. Dry completely 5. Apply drip wax - Used Squirt first with decent results - Changed lately to Mariposa drip wax which is more resistant and quieter during use: https://www.effettomariposa.eu/products/flowerpower-wax-bicycle-chain-lube To be honest the hot wax method may be better, but too complicated and time consuming...

Re: Velobuild GF-002 Bikepacking build.
Very nice build, thank you for posting! What kind of rear rack do you use, shown on the image? What is the weight? BR Chris July 17, 2023, 02:12:46 AM |

Re: Elitewheels Edge wheelset
My experience with the 45mm Elite Wheels Edge set after roughly 2000km: - Great stability - Very light - Combined with 28mm GP5000 and Ridenow TPU tubes - No issues with the 36T ratchet Freehub I can really recommend the wheel set. BR Chris September 29, 2023, 03:13:36 AM |

Project "Purple Rain"
Just want to share my latest Chinerbike project using a well known clone frame that was on offer during singles day sales in November and of course some other components off AliXpress. I know clone frames are frowned upon but I had a good experience so far, so here we go: - Frameset including seat mast and carbon handlebar - Ltwoo GR9 Hydraulic Gravel Brifters and Rear derailleur - Zrace XG hydraulic calipers - Elite SLR Gravel wheels 45x31mm - Continental GP5000 STR 30mm with Ridenow TPU tubes - ZTTO 11-46 ULT cassette - 105 Crankset with Stone 46T chainring - Mixed 5D Carbon saddle - Wellgo SPD pedals - Weight just below 8kg  I really like the frame geometry, so I decided to build a second bike with the same frame set and 1x11 gearing to be mainly used for indoor cycling on a Tacx trainer. First I tried to combine the GR9 brifters with a Shimano GRX 812 Garbaruk modded derailleur but could not get it to shift properly, therefore reverted to the original GR9 derailleur which works reasonably well. The frame interior looks clean by checking with an endoscope camera and the paint job is OK, but not perfect. The BB is a T47 which installed without any problems. The only thing I do not like on this frame are the plastic head spacer parts which require quite a lot of tension from the head cap to get all the play out in the fork bearings. In case of questions, please let me know. BR Chris February 17, 2024, 08:42:12 AM |

Re: Project "Purple Rain"
im interested in this frame too, which store is it? strangely enough Rocking store is nowhere to be found in Ali I got the frame from "Rocking Cycling" but you are correct, I just checked on Ali and the shop was found only after a second search... Here is the link: https://www.aliexpress.com/store/2189015 I especially love the integrated handlebar, the cables are routed below so really easy for a clean installation.

Re: Elitewheels Edge wheelset
I have the Elite edge 45 wheels with 28mm GP 5000's and the interface between rim and tire is pretty good. Below a picture how it looks on the rim and bike. Still very happy with the wheel set after 2500km.  And on the bike:  BR Chris February 22, 2024, 11:28:06 AM |

Re: LTWOO ER9 & ERX - Electronic groepsets
Thank you for the 51 pages of comments to the eR9 and eRX, very useful and interesting information! During the recent sale I could not resist to get an eR9 without batteries that came in delivered around 300US$. A great price if the thing works... For context, I upgraded my mostly indoor Zwift bike with the eR9 since the shifting performance of the GR9 never was great and the thumb shifter is not my cup of tea after trying it for several months. I think the poor shifting performance may have been due to the tight bends of the shifter cable due to the fully integrated handlebar. Going to wireless electric shifting did the trick for me... I had the GR9 hydraulic levers paired with the Zrace XG calipers, design, weight and color choice were attractive at the time. My experience with the calipers was less than stelar... the back brake did never work, even after several bleeds. The brake feeling was always soft and not very assuring on steep downhill rides. Installed the heavier L-Twoo calipers and breaking feel and performance is now good. I am running the eR9 in a 1x11 speed configuration, due to the existing chain and cassette. I really like the future proof option to upgrade to 1x12 or 2x12 if I want to experiment. Reading about the water ingress on the deraileur, I decided to use a heat shrink tube to slide over the port of the rear derailleur and then shrieked it to seal the cable in place. I expect this to solve the issue for the time being. Getting the L-Two app to work is a bit of an issue since the default language is Chinese... after some online search I figured out how to switch the language. Other than that the App is easy to use and the option to fine tune each gear to the tolerances of your cassette is a great feature. I currently run 46t x 11-36t for my indoor setup, no problem with the B screw to get 36t working even without a deraileur extender. Time will tell how good the system works and if the batteries discharge quickly. Since use the bike mostly indoors it should at least not cause any issues with water ingress.
