Component Deals & Selection / Re: New Ltwoo shifters... availability?
« on: December 28, 2025, 11:35:41 AM »
I used it for a while. Not reliable compared to sensah. The mechanism metal is possible to meet slip. This shifters after-sales rate is approximately 6%.

Component Deals & Selection / Best Choice of Shimano 2X12s di2 Components
« on: December 16, 2025, 01:04:59 PM »
Shifter: GRX825
Why not R9270 R8170 R7170: The top part of this lever is very sharp and it directly touches the controller's wire, it may break wire after many times of braking. GRX shifters design are good and also have high pivot points.


Front Derailleur: FD-R8150, FD-R9270
Why not GRX825 R7170: The inner side plastic of the front derailleur is very fragile. It is easily crushed.  But the GRX's issue is not serious compared to the 105's.


Rear Derailleur: RD-RX825, RD-R9250＞RD-R8150
Why not R7170: The plate body of this derailleur is made of thin glass fiber plastic. Very fragile. It also happened in RD-R8150. But the UT's issue is not serious compared to the 105's. DA's surface finishing is excellent.


Crankset: FC-R7100
Why not FC-R8100, FC-R9200: Glued Crankset. Still have many issues.


Caliper: R9270, Wheeltop One-Piece 7800 Caliper
Why not R8170 R7170: Many report about those caliper's rust. But the UT's issue is not serious compared to the 105's.


Chain: CN-M9100
Why not other: Full protective coating from inside to outside. If you do not always ride along the sea. Others are also ok.

Maintenance, Mechanics, & Tools / Difference Between Hyperglide Hyperglide+ Linkglide
« on: December 12, 2025, 11:32:22 PM »
Hyperglide：Smooth for small cog to big cog，but big cog to small cog still a bit shockness.
Linkglide：2-way shifting guides. It offers Upshifting and downshifting smoothness.
Hyperglide+: You can regard it as other 2-way shifting guides. It also offers Upshifting and downshifting smoothness in different ways.

Similarity for HG+ and LG: When shifting, the chain will engage with the two cogs and prevent relative slippage.
Difference for HG+ and LG: LG shifting delay is more compared to HG+.

Cassette Durability：LG＞HG＞HG+
Chain Noise：HG=HG+＞LG
Cassette Weight：LG＞HG=HG+
Small Cog to Big Cog Smoothness(11T→13T)：HG+=HG＞LG
Small Cog to Big Cog Delay(11T→13T)：LG＞HG+=HG
Big Cog to Small Cog Smoothness(13T→11T)：HG+＞LG＞HG
Big Cog to Small Cog Delay(13T→11T)：LG＞HG+＞HG

Road Bike Frames, Wheels & Components / Shimano CUES dropbar shifter weight
« on: May 16, 2025, 02:16:53 PM »

Suitable for CUES 10/11s(Inside it has a convert kit).
Actually if you connect it with Shimano 11s MTB Shifter M9000/M8000 etc, it is compatible with old 10s cassette.

Component Deals & Selection / 9, 10, 11 speed system's future - CUES or Old Standard?
« on: February 21, 2025, 05:31:35 AM »
Now Shimano release CUES drop bar system. Which is not compatible with old 9-11 cassette, rd, fd, and shifter.
Other brands still make 9-11 speed groupset.
Microshift - old standard.But new Advent, Advent X and Sword rear derailleur pull ratio is similar to cues.
Sunrace - old standard and CUES both. RS/RX/R9/MS/M9 for old standard, UX/US/U9 for CUES.
Sensah/Ltwoo Mechanical - old standard.
Sensah/Ltwoo/Magene/Wheeltop Electronic Groupset - Due to their rear derailleur can adjust cog pitch, they are compatible both.
TRP/TEKTRO - old standard(Not sure TRP HYWIRE)

Choose CUES
Bad - Heavy Weight, Delay shifting when upshift(big cog to small cog), Less Comptibility to Old Standard, Less choice for gear ratio.
Good - Durability, Encourages Strong Pedaling to Change Gears.

Choose Old Standard
Bad - Less durable compare to CUES.
Good - Compatiblity, Less weight for cassette.

If you want to build a new bike, which system will you choose in the future? CUES or Old Standard?

Road Bike Frames, Wheels & Components / Re: All Third-Party Brands Road Electronic Disc Small Groupset Weight and Other Info
« on: January 30, 2025, 02:43:17 AM »
I will upload later in GOOGLE DOCS.
ER9 small gruopset weighs 1321g(1x 1181g), R7170 small groupset 1216g(1x 1074g), R8170 small groupset 1123g(1x 1012g)
You can see new ltwoo caliper here:

https://www.ltwoo.com/en/productDetails?typeId=82&id=453

New caliper made in one-piece. But it still have a similar outlook comparing to old caliper. So it also has an old adapter. It is made in Ltwoo itself.
Zrace caliper is the similar version of Sensah HRD's. These two calipers(Zrace and Sensah)are all made by iiipro.
But ltwoo's brake power is better than iiipro.

Road Bike Frames, Wheels & Components / All Third-Party Brands Road Electronic Disc Small Groupset Weight and Other Info
« on: January 30, 2025, 12:40:56 AM »

These are All Third-Party Brands Road Electronic Disc Small Groupset Weight and Other Information.
1* Measured by Gravel Cyclist.
2* Measured by Josh Ross.
3* No 1x Support means you cannot remove Front Derailleur when you use single chainring. But you can still use 1x chainring after Front Derailleur installation.
4* TM to TM = terminal male to terminal male. If you don't want to buy original wire, you have to bespoke these wire from some headphone experts because there is no MMCX TM to TM wire at present.
5* So far, their reliability are not so good when compared to Shimano/Sram. If you just want to try something different or have very limited budget you can buy it.
6* Only list MSRP in China.

Road Bike Frames, Wheels & Components / Re: Lists of Frames who use Open Mold Carbonda/Flybike 696 707 686 etc

With so many branded 696s out there, it's surprising no one makes a direct mount derailleur hanger for this frame.

Great list
1 Quick Bike sells its direct mount hanger in taobao, it is compatible with some old Scott Spark Scale and Fuji Jari Direct Hanger.
2 Now new 696 is upgrade with UDH hanger, so you can just buy UDH Shimano Version direct mount hanger.

Don't know if you're still looking for this info but I just received my Sensah HRD G12 group set. 
Width is 35.1mm (measured 1.383")
Circumference on the grip is 14.8cm. 
So they are a little bigger.

Thanks a lot. Now I am sure it is not suitble my small finger ::)

Road Bike Frames, Wheels & Components / Has anyone measure the grip of Sensah HRD Shifter？
« on: October 23, 2023, 03:15:08 PM »
For 105 7020 Shifter. Its width on grips is 33.25mm and perimeter on grip is 13.5cm.
Has anyone measure these parameter on Sensah HRD Shifter？ I need to make comparsion between them.
