its the size of the connector at each end of the cable that is the issue. The L-Twoo I used one is _very_ slightly wider than a Shimano Di2 connector (maybe 5-6mm diameter). I had to grease up the connector and really jank it though (attached to a routing kit), which was a little un-nerving! I knew it would fit as I could get a brake cable through with the head (which is one of my internal routing go-to's), but it was a close-run thing!

I'm proud to say this exact bike got a "Super Nice" on GCN Tech's Bike Vault. I'm really happy with how it finished up, both in terms of performance and looks.

Not that specific iteration however I've done a build on the GT30 (previous model, as far as I can see the only difference is the mech hanger type now being UDH).

Generally, really like the frame. Only specific problem I had with it was running a power wire to the rear mech through the drive-side rear-stay, as it's _really_ narrow just behind the bottom bracket. If you're running a fully wireless setup you wouldn't have that issue.

The aim was to get something similar in style to a Canyon Grizl. I wanted lots of tyre clearance, and with significant difference to a road bike. For style I wanted something striking, and I like to be able to refer to my bikes by the colour (I already have predominately green (commuter), white (race), blue (winter) and red (old race) bikes. This one will most definitely be known as "Yellow"). It will be used for hitting local gravel and offroad paths, and potentially bike-packing at a future date.

I'm not the most experienced at ordered from China, so kept to AliExpress, and generally brands/shops that had a good number of orders, or where online recommendations exist. I've got previous experience with L-Twoo groupsets (Blue is on eR9). I try to build with some level of ease-of-maintainence in mind, so I tend to avoid fully-integrated headsets, and will always go for screw-in bottom brackets.

Issues during build;
1) The drive-side stay on the frame is very narrow, and internal routing of cables/wires is very hard. Getting the power wire to the rear mech ultimately required me to grease the head of it up (the L-Twoo cables have a very slightly larger head than comparable Di2) and drag it through attached to a brake cable.

2) The L-Twoo brake calipers refused to bleed. I suspect the bleed port nipples were not sealing (there is no o-ring that I can see, it's just a metal grub screw, and I definitely caught one leaking at least twice). I ultimately swapped to the ZRACE XG, which were far nicer to work with, and bled first time. Also slightly lighter!

3) Most stuff arrived (to the UK) within a couple of weeks of order. The Elite Wheels took 6 weeks from order to arrival. Still well within delivery expectations, but slightly frustrating as the final build was waiting on them. I have ridden this multiple times on a diferent wheelset, but today I finished the final build as shown. I've spent this afternoon setting them up on tubeless (along with a fair amount of swearing, obviously)

4) Not an issue, but a note in L-Twoo installation. Most issues I've heard of seem to be around water ingress on the mech power cables. I pre-emptively add extra protection here with liquid electrical tape ( https://www.amazon.co.uk/Liquid-Electrical-Tape-Insulating-Black-125ml/dp/B0CX58Y6VF ). This has served well on the eR9-equipped Blue bike (which has done several hundred miles in Yorkshire rain), and I have confidence that the same process will work here.

Really happy with how it looks, and handles. The final fit is based on my road bikes, with a bit more height at the front. Final weight (with pedals, bottle cages, Garmin mount and sealant) is 9.2kg, and a lot of that is the tyres (705g each as listed weight). Clearances on the frame are fine with these tyres, though I doubt I could size up to 2.1/2.2 on the rear, the limit being the clearances on the rear stays near the bottom bracket. It's done about 250km of mixed terrain on the other wheelset, with no issues. I much prefer the feel of the eGr shifters compared to the eR9...they have a far more tactile feel to the shift buttons, and the hoods are slightly chunkier (I find eR9 hoods a little too narrow). I went with a 46T max on the rear as that is the max stated capacity of the eGr. I _think_ it could take something bigger, but I don't really feel a need for it...42-46 is a far more generous gear than I'm used to.

Final cost is about £1500 + import tax. The import tax is a little tricky to determine, as some stuff came with other items not directly related to the build, and the entire package was taxed. If they had come separately, I probably would not have been charged! I didn't do amazingly well at the AliExpress price game (for example, if I was ordered now there are some better deals on that I got). On top of this I also ordered some spare parts (mech hangers, bar tape, some inner tubes for get-home emergencies) and some accessories (like a bar bag).

I suspect Brexit has mucked up shipping to the UK royally :-( A lot of items seem to come via the Netherlands now, which tends to add 2-3 days. Nearly everything else arrived in 7-14 days from order (the next slowest being a parcel of multiple items that was grouped, and that took a few days extra to ship). The other "large" item (which was my frame, from CWind) was ordered on the 1st June, shipped on the 12th and arrived on the 26th. That was routed via the Netherlands, and had a 48 hour delay for a customs fee.

My main worry is that the parcel had gone AWOL somewhere, and that doesn't seem to be the case, so that's a relief. I've got everything in a big spreadsheet, so next time I do a bike build I can look at the shipping speeds for various methods and have a better idea of when stuff will arrive!

I have had the tracking update that they'll arrived in the Netherlands. 24 Days of radio silence.

As far as I can work out "Heavy Line Parcel" is shipped via sea, whereas everything else is via airmail...and of all the sellers I ordered from, only Elite uses this shipping method (UK, so don't get that much choice in shipping, unlike EU).

The frustration for me is/was that I've taken some wheels off another bike to get the new bike built up, but don't want them tubeless (and different tyres/axles)...so right now the workshop has 2 half-built bikes :-D Once these wheels arrive I can get all components on the right bikes, and have a less cluttered workspace!

That is taken into account...shipping was 6th June. Took 6 days to clear Chinese Customs, then Country Departure Notification on 18th June.

For everything else, arrival-at-destination  country notification was 2-3 days later. These have gone silent.

I ordered the parts for a gravel build beginning of June. All the parts (from multiple sellers on AliExpress) arrived within a couple of weeks (to the UK). The slowest bits came via the Netherlands (inclunding the frame, the other "big" part).

The wheels (ordered from EliteWheels), however, are still showing as in transit from China to the Netherlands, and have been since 18th June. I've contacted Elite via message a couple of times, and they say it's "normal" for 25 to 35 days shipping time.

Do EliteWheels use a remarkably different shipping method to anyone else on AliExpress? it's notable that their order does not have a Delivery Guarentee, just a shipping one. Ironaically I thought they were the going to be the most reliable seller, as they are one of the bigger names I was buying from.

I've ordered all the parts, and currently waiting on arrival (everything is shipped apart from the frame). I'm planning to use an 11-46 12x cassette initially...I can then see if there is any scope for expansion once it's built-up.

I've been running eR9 on my winter bike for about a month (in summer it's used for wet riding), and it's been flawless. The only thing I've done is apply liquid electrical tape on the power cable connections into the mechs to improve water-proofing, so got a fair amount of confidence that the eGr will be fine.

Seemingly like everyone else, I'm planning to build a gravel bike in the next couple of months. Currently in the process of rebuilding a commuter with some L-Twoo eR9 and parts, and then will get going.

My plan is to build something similar in capability to a Canyon Grizl...50mm+ tyre clearance (ideally MTB wheels), and (assuming I get on with the eR9) I'll probably plump for the eGR 1x12 (which I believe limits me to a 46-tooth rear). A screw-in BB (BSA or T47) is a must, due to previous experences with pressfit BB's. THis would be my first prmiarily chinese build...I've used wheels and occasional components before, but never a full build.

The LightCarbon LCG071S-D looks promising
https://www.lightcarbon.com/new-carbon-gravel-frameset-with-integrated-stem-system_p171.html

...however I'm only used to ordering off AliExpress, and I cannot find a LightCarbon presence on there, so struggling to get an idea of cost. Do you have to contact the company directly?

I've also found this
https://www.aliexpress.com/item/1005005678330464.html

Which looks good, but for this struggling to find any reviews or opinions.

Finally, I see a lot of notes on vouchers and discount codes...is there anywhere to find these?
