Re: Groupset News
Here is some news about eGR: Currently, eGR has started small-scale tests in the pre-production and final stages, and it is expected to be available for sale in early next year (after the 2024 Chinese New Year). I have some pictures of eGR from friends who have received the kit. https://photos.app.goo.gl/Cc4wmfB5XBxMcgTw7 The main focus is on comparing the weight with the GRT Mechanical Carbon Fiber Hydraulic Kit: The eGR rear derailleur is 65g heavier than the GRT rear derailleur. The new version of the clamp has a more refined appearance and is 45g lighter per pair. The eGR shifter no longer has a gear mechanism, making it 52g lighter per pair. However, due to the additional weight of batteries and cables compared to the mechanical kit, it adds approximately 78g. Therefore, the eGR weighs about 50g more than the GRT carbon fiber overall, excluding the battery mount plug. The eGR brake lever and rear derailleur housing are made of carbon fiber, while the rear derailleur guide plate is made of aluminum alloy. Compared to eR9/eRX, the shape of the eGR brake lever is less outwardly extended, the button shape is larger, and the button travel has increased, resulting in a better feel. Apart from these changes, there are no significant differences. Although the eGR left-hand side has buttons, it has been confirmed that it cannot control the same rear derailleur with two hands like SRAM. The buttons on the left side may be designed for electronic seat post adjustment (I'm not sure if this is accurate). The eGR features a newly designed integrated clamp that is lighter in weight. However, due to Shimano's patents, there have been no improvements in the bleeding method. October 16, 2023, 08:28:41 PM |

Re: LTWOO ER9 & ERX - Electronic groepsets
What 11 speed 11-32t cassette would you recommend with ER9? Nothing crazy like DA/Red, I was thinking about trying SLR2 sold by Lexon store or Sunshine ultegra October 18, 2023, 12:11:12 PM |

Re: LTWOO ER9 & ERX - Electronic groepsets
You guys are really buying this stuff even when youtubers known for loving Chinese stuff gave it a red card? Well, they are only youtubers....they seems to forget how hard sram failed when starting with their electronic groupsets..i remember a race, where 5 people were sitting at the side of the road not being able to change gears with their sram, sebastian kienle had failures on racing hawaii with sram.. So, why not give LTWOO the time to get stuff done... We are currently planning to sell these units, even with aliexpress selling it lower than we buy directly, but customers are in the market for budget custom gravel builds....and it is great for the market....we need to show shimano, that their pricing needs to be adjusted. the low prices on the shimano di2 sets are made by the dealer ships, shimano has still their high price attitude and in europe, margins are not there....a normal bike shop buys shimano stuff cheaper online at some outlets, than referring to the official distributor...

Re: LTWOO ER9 & ERX - Electronic groepsets
Battery level is now accurate within the app. Seems like it needed the first charge/discharge cycle to calibrate itself. Also, the sleep and wake up functionality works fine. Once the bike sits for a while, nothing happens when you click the shifter. But the slightest vibration wakes the RD back up and it shifts. So here's to hoping that the groupset doesn't fall asleep when riding on super smooth roads  Luckily I don't have many of those where I live. October 20, 2023, 03:27:41 AM |

Re: Wiggle/Chain Reaction Filing For Bankruptcy? - Sale On Everything
Serves them right for refusing to sell Shimano and SRAM components to the US. You're right, they deserve to go bankrupt for honouring their agreement with sram and shimano. October 20, 2023, 11:39:10 PM |

Re: LTWOO ER9 & ERX - Electronic groepsets
It's like a quarter of a mm of play, tho it shifts pretty nice now but I want to know if other guys are experiencing this so I can report this to LTwoo I can move the FD cage by that amount if I try. But the motor or some sort of spring tension is acting against it. So there’s not really any play. I’ve done 100k so far on er9. It works great. I wish there was a bit more tactile feedback from the shift buttons. It’s a bit hard to tell whether or not I actually pushed the button. Apart from that all is good. October 29, 2023, 08:21:06 AM |

Re: LTWOO ER9 & ERX - Electronic groepsets
I fixed it now and it shifts as expected. It seems to be a combination of things. My TanTan TT-X38 has the FD hanger sitting very far inboard. I’m using a SRAM Wide Axle BB30 crank which has the big ring sitting at 49mm. So particularly far outboard. And I think the er9 FD is a little bit more limited in movement compared to other FDs - mechanical ones for example. I had it at the outermost extreme setting with the high limit all the way outboard at 99 and it still wouldn’t shift well enough for my taste. But I spacered the bolt on FD hanger about 3mm further outboard and now I’m able to set it up so it shifts super smooth. So it’s more the frames fault than the groupset‘s IMO.
