Re: JH017 grevil/gravel frame set? I don't have any real info to add, just that I went through the same thing when I was researching gravel bikes, I just think the Grevil is so cool.  I ended up deciding that there were no brands that are well-loved by ChinerTown that make it, there's no real reviews on the frame, and it's often a bad idea to buy frame that are direct copy of another (because they may not have done Engineering, just copy the outer geometry and thickness, they may not know the actual layup schedule and material spec).  Too much risk for me, so I went for a Carbonda.

Edit to ask, which carbonda frame you've got?
I went with the CFR707, got some pics and writeup in the thread here

Re: Spcycle New Mold G056 Carbon Gravel Frame

More bike brands need to offer this...

Opening holes in the frame down tube requires modifying the frame mold. This is cumbersome. We designed this headset cover. So the frame can achieve semi-internal cable routing.

Tsunami Seaboard GR02 Budget Gravel Build I haven't seen much discussion about this affordable aluminum gravel frameset, so I decided to buy one and assemble a really budget focused build (ignoring the wheels which I already had on hand). I bought nearly everything on Aliexpress and the total build cost (ignoring wheels) came to just a bit over 1000 CAD including shipping.

Everything eventually arrived in good shape, and the frame itself was very well packed. The frame is really decent quality and definitely exceeded my expectations, the fork is also reasonably nice, with no obvious defects. It is a bit strange that the fork required the disc adapter set to 140 mm even though I am using 160 mm rotors, perhaps you could use 180 mm rotors if you wanted?

It was a bit confusing to figure out how to route the shift cables and ultimately decided that crossing them inside the downtube performed the best. It was also necessary to use anti vibration foam on the rear brake cable housing to keep it from rattling.

I used Kalloy UNO stem and handlebars, which are unbeatable price/performance, and used the L-TWOO RX 12 speed groupset, which also exceeded my expectations. The shifting is nice and crisp with the front shifting being a bit worse than my other bike equipped with Shimano 105 R7020, but overall very comparable. I did have to swap out both cable pinch bolts on the front and rear deraillieurs but other than that no major problems so far.

The brakes are Zrace BR-005 and Zrace 160mm rotors and they perform very well, comparable to my R7020 hydraulic brakes using 140 mm rotors on my road bike. I am using Jagwire compressionless housing front and rear.

The wheels (which I already owned) are Light Bicycle AR46 laced to DT350 hubs, and are wearing Continental Terra Speed 700x40 tires.

Total weight without pedals is a very respectable 8.8 kg.

For reference the frame is size 53 (L) and I am 179 cm tall, it fits perfectly.

After 100km so far my experience has been overwhelmingly positive! I had to tighten the headset after the first ride, I'm sure that was just the crown race settling a bit and since then it has remained tight with no play.

Re: Groupset News I have finished my budget gravel bike build using the L-TWOO RX groupset, so far I am really impressed by it! Ignoring the obvious downside of thumb shifter positioning it is performing really well so far. I had to replace both front and rear cable pinch bolts which both sheared apart at ~4 NM, fortunately they just used a removable nut so it was an easy fix. I also am really impressed by the Zrace BR-005 brakes, they are easily comparable to my road bike which has 105 R7020 hydraulics albeit using 140 mm rotors (I am using 160 mm with the BR-005).

Re: Groupset News Totally unsourced part 2: Decathlon is rumoured to be considering speccing their Triban bikes with L-TWOO hydraulic...

L-TWOO are already present in some Genesis bikes retailed by Walmart, but scoring Decathlon as an OEM customer would really catapult the brand into the next echelon of component supplier

Re: Chasing wind-GT20 OR Airwolf YFR045 carbon Gravel frames , any experience ? After my own build I was asked by a friend to build him one in matching size 52 and color of choice. This time using a full Shimano GRX groupset with Garbaruk cage for an extended gearing of 11-46.

The complete build came in at 9kg with 32mm tires and heavy steel casette and chain. The new owner is very happy with the result both in price and quality.

Here some pictures:

Re: Xoss/iGPSport, other computer companies? I've had my iGPSPORT i50S for a few months now and am generally impressed. It's a fairly basic GPS/Beidou computer that can interface to a heart rate monitor, cadence sensor, and wheel speed sensor, but not a power monitor. The screen is a simple LCD display with no maps or navigation. I ordered a package that included the heart rate, cadence, and wheel speed sensors as well as a mount.


The good:
  • Garmin-style mounts are cheap and easy to find.
  • Speed, distance, and elevation calculations are all fairly close to what I've calculated with other means.
  • It was easy to pair the device with the sensors, and the connectivity has generally been good.
  • Battery life seems pretty good. It could easily last an entire day of riding.
  • It's durable. I left it on the roof of my car and it fell off when I went around a corner. I found it a couple days later, lying in the gutter. There's just a minor scratch or two.
  • iGPSPORT has good tech support. I've emailed them twice with questions and got useful answers within 24 hours in both cases.


The not as good:
  • It seems to lose GPS reception easily when riding in forested areas. I've had a couple rides where the reception drops out and recovers a few seconds later, and it happens repeatedly. The beep when this happens gets annoying, although the total distance still seemed accurate. (I did not have the wheel speed sensor on the bike at this time. There aren't many trees where I usually ride, so this isn't a big issue for me.)
  • When I first got it, it reset itself periodically during a ride. I emailed iGPSPORT and they suggested a software update, which fixed the issue.
  • The app is a bit unpolished. Some of the screens are awkward to use, and there are some issues working in miles.
  • The "odometer" on the computer is not adjustable, and there is no support for multiple bikes on the computer itself. However, you can download the recorded rids with the app and then assign them to different bikes. The app will then show the cumulative distance for each bike.
Overall, I'd happily buy it again. The wheel speed sensor isn't essential, but it does allow it to detect motion and start recording more quickly than when on GPS alone. It should also help when there are satellite reception issues.

Re: Groupset News RX 2x12 carbon hydraulic left brifter weight


A L-TWOO employee recently posted a thread sharing some anecdotes on the company's hydraulic development process. It's too long and technical for me to properly translate but you can get a basic idea with machine translation. The gist is that L-TWOO faced some pretty significant patent barriers which limited their design direction. They eventually settled on a Campy style design for reasons practical and legal: the vertical master cylinder layout performed the best and also left the most room for the shifting mechanism. But most importantly, Campy didn't patent their hydraulic implementation!
