      Sick! Yea i was kinda in the same boat and did an impulse buy and so far it's been okay aside from the button thing and that one hotspot on the shifter for the hydraulic hose but that was pretty easily fixed with some well placed bar tape. Looking forward to hearing your experience!

      @mrpercussive  10 หลายเดือนก่อน +1

      It's started to warm up so i havent had any of the shift button issues come back. That said, they might when winter hits again. I suspect that might be the reason for the updated buttons on the new generation. Aside from that everything is working well and software updates are pretty cool with the latest one having cross chaining protection and such. I did email LTwoo about the buttons a few weeks ago and did not get a response. I just dm'd their IG account today so we'll see if i get one from there

      @@mrpercussive The current sale was too good to pass up for the ER9 (around $331 USD before tax). Even with all the quirks, I think I can work my way around the issues since I don't ride in the cold or rain. Hopefully they'll get back to you in regards to your shift issue. I'll be installing this on my back-up bike, I'll be keeping my main bike mechanical for the foreseeable future! 😁

      ​@@mrpercussive I installed the ER9 groupset a few weeks ago. It took a few rides to really dial it in, but so far it's been riding without a hitch! I also used the opportunity to upgrade to a lightweight 12 speed cassette which helped offset the weight difference with the carbon ERX.
      For more extreme weather/travel/long distance riding, I might stick with mechanical. Though that has less to do with LTwoo and just the nature of electronic shifting in general. Overall I can highly recommend the ER9 for those with experience doing their own bike maintenance.👍

      That's definitely a warranted concern. I had my doubts as well and that's why i waited quite a while before finally pulling the trigger. For the price i was willing to take the plunge and hopefully i had waited long enough, they would have ironed out the kinks and i would hopefully get the latest iteration. Klein Concept just posted an update on his ERX slapping his bike in the shower to test for water ingress and looks like his is doing alright as well. I got my ER9 a little later than his ERX too so I'm probably alright

      You can get after market pads for these calipers. Look for those that are 26 mm wide in total and 30 mm high in total, including the hole for the safety pin. Look for i. E. 'Risk Dust DS-12S'

    Hello! Do you think you could do a video on the fron derailleur first setting? I can't make my chain to stop rubbing the inside of it. I've tried it manually (with the button on the shifter) and the app (this last one tends to disconect), and it seems like it blocked to move the position in or out... like it has reached the limit... I've seen ALL the youtube videos and no one has covered the front derailleur in detail. It would be very helpful 🙏

    • @mrpercussive
      @mrpercussive  5 หลายเดือนก่อน

      Use the app? Set the limit and index in there. Also remember there's the trim function. Shimano has the patent for auto trim so you have to manually trim on the LTwoo just like mechanical groupsets. Click once to shift, click again to trim

    • @mrpercussive
      @mrpercussive  ปีที่แล้ว +1

      No... there are two buttons on each lever. You can however switch the left and right for rear and front derailleurs though and you can do it mid ride in the app so if one of the shifters' battery dies, you're not SOL and can get home.

    @qwertyazerty2137 ปีที่แล้ว

    I just installed my ltwoo R9 hydraulic groupset and I am disappointed. The shifting resistance is appauling. I used ltwoo's supplied cable and a jagwire housing. The cable looks good quality. Copper-colored so maybe it's coated with something. It's definitely polished and smooth so maybe it's the cheap housing or the fact that I routed it on the front side of the handlebar where the horizontal bent is bigger forcing the housing to bent more. The levers have another groove to route the housing on the back side of the handle bar for a less bent of the housing so I must give it a try.
    But the worst thing is that the left lever bleed port screw is tightened so hard that it won't budge. I stripped and rounded its head trying to loosen it and now it's stuck forever. Suprisingly I was able to bleed the system using just one syringe plugged into the caliper so from top to bottom. But anyway I am waiting for the seller's response and his solution becasue this lever qualifies for a replacement.
    Other drawbacks:
    1. Rubber of the hoods is slippery although it has a matte feel to it and has a texture. Shimano's hoods are way more grippy.
    2. To save manufacturing costs, for the left lever they use a lever from a 2x groupset (maybe rx) because it has guiding groves for the shifter housing under the hood. They simply just don't put the cable ratchet pulley and shifitng paddle and trigger. That's ok but without this ratchert, there's a gaping hole underneath the lever where all the gunk and dust may build up. Also while on the hoods having your index and middle fingers wrapped around the hood, you can feel that hole and it's edges under the fingers tips which is uncomfortable. Especially when you grasp firmly while pedalling hard out of the saddle uphill. How much would it cost them to desing a simple plate cover with an i.e. elastic latch similar to those of battery compartments in tv remote controllers?
    3. Downshift trigger is in awkward position. Its position and overall lever shape is heavily inspired by Campagnolo Ekar levers which apparently have the same problem which Paul from Mapdec Cycles reported in one of his reels. On the hoods to reach it you have to sort of lift your hand and twist it inwards. also when pressing down the trigger, if you have your fingers wrapped underneath the lever, they are right under the trigger and obstruct its downward travel so you also have to move them away. I would expect the trigger to be place more towards the front of the lever just like it is in ltwoo's mechanical road levers like r9, r7, r5... Also, it offers up to 3-4 downshift with single push. I think this is unnecessary, because it causes excessive unwanted downshifts. It could be justified in the road RX groupset in finish line sprint situations, but this is a gravel groupset so I think it's pointless and useless. On the plus side, the trigger is ergonomic and right were you'd look for it while on the drops.
    4. Lever instllation is troublesome. The bolt clamp is located in the center of the lever body so the vertical part with the master cylinder obstructs access to it to an extent. Also, the bolt is very hard to reach becuse the rubber of the hood is very tight and does not peel off enough to expose the bolt. You need to have an extended hex wrench with a ball-head end and prefferably with an attachable handle. With a standard-sized wrench it will be very hard to reach the bolt. For comparison, in Shimano levers the bolt is on the outer side of the lever body and it only takes to slide the wrench under the hood to reach it.
    5. The rear derailleur isa bit too big. I've installed it on an Accent Furious Pro frame and noticed that if I loosen the b-tention screw too much, the front of the derailleur where the clutch is located touches the chainstay and wedges on it preventing normal operation. Also, the part of the derailleur with this clutch is visibally made out of some kind of composite material, probably based on nylon. It's definitely not metal. The rest of the parts, like the pantograph, pulley cage are indeed metal. Unless you buy a version with a carbon pulley cage of course.
    Pros:
    1. Overall quality is good. The logo imprints are good. They are thick and have a nice sort of brushed aluminum texture.
    2. The shape of the hoods and lever blades is ergonomic. They feel good under the fingers both on the hoods and on the drops.
    A this point I honestly do not recommend GR9. It's not worth the risk. I can recommend R5 because I have had these levers for two years now and they have not failed so far although the shifting resistance is also quite strong but not as strong as with these GR9 eventough I have the shifting cable routed along the front of the handlebar as well . The overall build quality and shifting is comparable to Shimano Sora.

      @qwertyazerty2137 ปีที่แล้ว

      ​@@mrpercussive I know, still I wanted to give this opinion because in terms of the ergonomics, the potential problems with the bleed port, one may experience this with any other hydraulic groupset from ltwoo. All the more in none of the reviews of these groupsets that I found on yt, including GR9 (which are not that much and all of them are russian), somehow none of the reviewrs reported these issues. I fell kind of a duped, especially considering ltwoo comolete lack od technical support.

      @@qwertyazerty2137 Fosho... yea I had mentioned my issues with the ergonomics on mine like the hotspot on where the hydraulic hose pops out. Bleed port on mine is pretty interesting with the dual ports. I've pretty much done a full bleed once and then have also done the lazy man half bleed like how i've done Shimano and it's been pretty solid. It's been pretty solid overall minus a few quirks here and there. Seems like they're constantly updating the groupsets even after official release so I can only see improvements being exponential with ever new release

      ​​@@mrpercussivetoo bad that in order to get these Improvements you will have to cash out for a new entire groupset or conponent. This is like rushing to roll out an unfinished product and from the earnings funding its final finish.
      By the way, I bought mine from the same seller - 80 Designer Store - who now claims that I damaged the bolt by using improper tools and he offers only a replacement bolt. I was afraid that warranty for anything from ali is fictional. I hope your set will not turn out to be faulty forcing you to deal with this seller. I concated ltwoo directly, but I suppose it's a fool's errand...

Just two screws if i remember correctly and stretched out the spring. Funny is that same thing happened to my buddy's di2 105 so it's not just L-Twoo. However I did have some water ingress issues. Got caught in some real heavy rain and my battery wouldn't hold charge for longer than a day. It got warrantied though and a new one was sent out and i'm all good again.
