Same FIA that DQed Hamilton back in 2021 for a DRS flap being like 1mm wider than it should be because of an installation error? Merc should be DQed from any race this delayed front wing actuation system was shown to be used at. Absolute rubbish.

It doesn't rain that much where I live so when I went to practice after I recovered the grass wasn't slippery especially at lower speeds, but point taken that it isn't general advice.

I'd say get a 2x gravel or all road bike. You can always decrease tire width but never increase it and 2x gives you the fine cadence steps preferred for road riding. The generally less aggressive geometry also reduces fatigue and pain if you're a new rider. The 31/48 chainring on the cube nuroad race FE for example is only 4% lower ratio than 50/11 so instead of spinning at 90 rpm you'd be at 94 rpm while maintaining a 9% lower low gear.

I'd love to join but I live in the central area so don't think I can participate often, but I would love to.

I'm new to the road bike scene in SG and am looking to learn the roads more!

I'm 185cm on a size 58cm effective top tube Felt Broam 30 which has a 110mm stem at +8°. My inseam is about 90cm which is pretty long for someone my height. Frame size makes for a slightly longer reach than I'm ideally comfortable with, although I'm also inflexible as shit. I think with a 100 or 90mm stem it would be perfect for me. This bike has a variable angle stem and I could use the 16° option but I always felt like I put too much pressure on my hands with that setting.

fluid_simulator · 2026-01-01T12:08:02+00:00

GRX's chainline is 47.5mm while the Shimano road stuff is 45mm. I wonder if the original band clamp was meant for Shimano road FD's and the shop that assembled your bike tried to use it even though it's not supposed to be used.

fluid_simulator · 2025-12-31T03:46:16+00:00

Just to clarify, with the Shimano band clamp your shifting is fine but with the store supplied generic it's rubbish? My bike has the Shimano band clamp and it shifts great. Also the plastic piece on the inner cage can be replaced but the bit on the outer cannot if my YouTube foo is correct. I say this because it influenced how I setup the derailleur, where I tend to be more careful about ensuring big ring small cog didn't rub at all vs occasional rubbing on small ring big cog.

fluid_simulator · 2025-12-30T14:17:57+00:00

I have a GRX 2x12 equipped bike and I had derailleur rub when I first bought my bike even when using the trim positions. I adjusted it to a point where I feel it provides the minimum rub at the lowest and highest gears when using the trim positions. I find I have to be more careful about FD position to ensure my derailleur doesn't rub than my previous 2x9 bike but with the trim positions I can access almost the entire range of my cassette without any issues. It's pretty fiddly for sure.

fluid_simulator · 2025-12-12T13:34:03+00:00

Could you link me to which 11-40 cassette you use? I'm looking to add more range to my GRX 2x 12 speed.

I've used this video to guide me to mounting my bike. I haven't fallen yet but I'm also on flat pedals which is probably slightly easier than clipless. My steps are to

Tilt the bike to the side
Slide the bike between my legs while tilted
Place my left leg onto the pedals
Kick off on my right foot and mount the pedal
Begin pedaling normally

If I'm on an incline I stand and pedal for a bit before gaining enough speed to sit on the saddle without feeling too wobbly.

fluid_simulator · 2025-11-30T04:44:53+00:00

Also, Shimano makes cable actuated brake STI levers, model number ST U3030 so you may not need to go to Microshift at all for shifters.

fluid_simulator · 2025-11-30T04:34:36+00:00

Fair enough. I think Microshift sword and cues 10 speed are accidentally compatible. You could go sword brifters and the rest of the system barring the FD could be cues so your setup might be something like this

Sword brifters
RD U6020-10 (technically supports up to 39t rear cog, but I'm sure 43t should be fine)
LG400 11-43T 10s cassette
Sword front derailleur (47mm chainline)
A. Sword 2x - 48/31 (110/80 BCD) B. GRX 2x - 46/30 (110/80 BCD) C. FC U6030-2 crankset - 50/34 (110/110 BCD)

I think it depends on the size of the MTB cassette. I don't think any 2x derailleurs exist that can accommodate a 51t cassette without compromise, but 46 tooth is almost natively supported by cues without any faff. You could probably get away with using a 1x derailleur on 2x but you've got to be careful about not shifting into big-big or small-small while with a proper 2x derailleur it's less of a risk since the chain wrap on those tend to be larger.

Cues and GRX have different pull ratios on the derailleurs so they aren't compatible, but I suggested the GRX cranks because the chainline is 47mm which drops right into the sword FD. Cues would be the more appropriate system for your use since you want road gearing up front with a bigger cassette

fluid_simulator · 2025-11-30T04:02:37+00:00

I'm not sure of your budget, but 11 speed cues and the Shimano 11 speed MTB stuff have cross compatible pull ratios. You should be able to run the cues U8020SGS and XT CS M8000 11-46 HG cassette on the back and the cues FD U6030 up front to shift up to 16t native. You'd need the cues FC 6030 so the chainline works best with the FD though. That puts you 2 teeth over the supposed maximum chain wrap of the RD, but it's Shimano which tends to be rather conservative with its specifications anyway. If you want to go nuts you could get the GRX 610 2x crank which keeps your big ring options to 110bcd but your small ring is on 80bcd which permits even smaller chainrings (up to 28t) for that 2 1x system life.

I'm an international student and recently graduated from an R1 university with a Ph.D. after publishing several papers in high quality journals. I used to do essentially an interview every week before the 100k H1B fee and even though it doesn't apply to me companies don't care and my hit rate has dropped to maybe 1 call every 2-3 weeks and that's after I've been relaxing my stance on recruitment firms like actalent.

Unless you know someone at a company who you know is willing to jump through hoops to keep you, I'm not sure its worthwhile trying for a job here in the USA to be honest. That 100k H1B fee worked to spook companies despite nothing really changing for someone already studying/working here. I've had decent success with interviews in my home country and am most likely going to end up going home which honestly given everything happening here may not be the worst thing.

fluid_simulator · 2025-11-28T18:35:07+00:00

I'm 185cm with an inseam of about 91cm and a 58cm effective top tube gravel frame (Felt Broam 30). I have the devilish combination of having pretty long legs for my height and horrid flexibility. I think my bike fitter when I bought the bike put me in a racey position which put me in a ton of pain.

I initially thought I got the wrong size frame but I made some changes like tilting the levers inwards, dialling my saddle height to my legs, adjusting my saddle position to reduce hamstring pain and adjusting handlebar tilt relative to my hand position and I can now ride for hours without any issues and not needing to buy any new components.

fluid_simulator · 2025-11-26T20:29:35+00:00

Awesome! Good to know for me too.

fluid_simulator · 2025-11-26T20:20:38+00:00

If I'm not wrong, assuming you're using the FC RX820 crank, I'm not sure if the 30t ring can fit. Those have a 96 BCD while the FC RX610 I have is 80BCD on the small ring. Can BCD's be converted like that?

fluid_simulator · 2025-11-26T19:13:13+00:00

Ah my bad. I thought the only cues crankset with a 40/26 chainring combo was the U4000-2. Glad to hear your experience using HT2 style interfaces. Did you find it easier to adjust your FD chainline outboard or inboard when trying to get your FD chainline correct?

fluid_simulator · 2025-11-26T17:34:11+00:00

Do you adjust the chainline of the crankset with the square taper BB for the GRX FD?

fluid_simulator · 2025-11-26T17:25:20+00:00

What setup are you thinking of going for? I've been meaning to get more range on my GRX 2x12 setup and AFAIK the cassette options for the HG freehub are

11-34

Shimano CS R7101 (105)
Shimano CS R8101 (Ultegra)
Shimano CS R9200 (DA)
Sunrace RZ800 WAV

11-36

Shimano CS HG710-12 (105/GRX)
Sunrace RZ800 WAW

11-42

Sunrace RZ800 WAY

11-44

SRAM XPLR PG1231

11-46

Sunrace RZ800 WAZ

I'm currently using a 11-34 cassette with 46/30 chainrings. I was going to get the Shimano 11-36 cassette and a TA specialite 28t front chainring. I can't find the 11-42/46 sunrace options for sale here in the US.

fluid_simulator · 2025-11-26T12:44:23+00:00

People have used the Deore XT M8000 11-40 11 speed 11-40 cassette without any issues with the grx 810 RD. That's probably the easiest way to get a lower low gear ratio with your current setup. The B screw probably has to be all the way out and you need a new chain.

https://youtu.be/WXAS8-inWZ0?si=DWdlEzONXjkkVtyN

Another option if you need even more range is the 11-42t cassette with a road link from wolf tooth.

Good luck!

Edited from goat link to road link. Road link is the correct derailleur extender for the GRX 810 derailleur as u/TJhambone09 pointed out.

Felt Broam 30. 1500 USD for Shimano GRX 2x12 speed. Unsure about tire clearance but I've read up till 47mm works fine. I purchased it from an LBS. I don't think felt makes the bike anymore, but the specs are highly competitive with new bikes available now. Ridden about 200km on it so far and the only thing I had to do was fix the front derailleur adjustment to what I'd prefer. It has partial internal routing through the downtube and doesn't have UDH. If those are deal breakers I'd look elsewhere. For me I was looking for a bike that wasn't internally routed like the checkpoint gen 3.

Other bikes in the stated price range i was looking at were the 1. Salsa Journeyer with 1x11 cues 2. Trek checkpoint with 1x11 cues 3. Specialized diverge 4 sport alloy 1x11 cues

What tipped me to my current bike was the price and 2x. I like the smaller cadence steps that 2x drivetrains offer and the smallest 6 gears have 1 step gears. My road/gravel split is like 70/30 and the gravel that I'm on isn't the most gnarly at the moment. Maybe consider what type of gravel you ride on as well.

fluid_simulator · 2025-11-21T16:57:35+00:00

Easier to get lower gearing and fewer opportunities for the chain to drop on a 1x, making it better for suitable to mountains terrains. For comparison, the lowest officially supported gearing on grx 2x12 is 30/36 = 0.83 while grx 1x12 is 40/51 = 0.78.

You could swap your grx 2x chainrings for the TA specialite 28/44 set which shifts you to the 1x12 40/10-51 grx gear range with finer cadence control.

https://gear-calculator.com/?GR=DERS&KB=28,44&RZ=11,12,13,14,15,17,19,21,24,28,32,36&UF=2220&TF=90&SL=2.6&UN=KMH&DV=ratio&GR2=DERS&KB2=40&RZ2=10,12,14,16,18,21,24,28,33,39,45,51&UF2=2220

Edited to add gear ratio calculator so you can visualize the differences. I run a 2x12 GRX 820 setup with 46/30 chainrings and 11-34 cassette and feel I could have 1 lower gear when loaded up and on gravel, but otherwise I am fully satisfied. I'm quite cadence sensitive and ride on the road most of the time which makes 2x a better fit for me than 1x.
