wow... even it is correct but too straight not good. LOL

Should encourage normal ride and not aim for speed for MTB.

This kind of bike only 1 size. So it is totally depend on the height of the rider.

Ride in resident area use cheapo cheapo chaoyang tire also not bad la. bang of buck already. Hihihi.

I think the issue he's having is going up slopes. He's flat is ok.

Yes. But as you can see. The seatpost is at its minimum height. Unless the rider is a kid.

I took a closer look, looks like as other said, the seatpost is too low

unless he height is <150cm

Yeah... noticed like you said b4 the saddle height looks a bit too low... but I'm guessing he could benefit having variable ratio if he's doing mixed terrains on this bike.

If you observe.
Many cyclist adjust the seatpost heightso that when they stop. Their feet can touch the ground when seated. When they cycle, their leg won't be pedalling efficiently.

I had tried telling a few cyclist in my taman about this. But they still don't get it.

Why suddenly got 12 speeds component flood in the market ?

Good to go?

I have SLX 12 speed. If your ride is mainly consist of steep technical terrain it is worth the 50~52 tooth.
But if your ride is mainly flat, not so steep, I think it is useless.

Since you have 12x drive train, need to ask you that switching from big cog to small cog in 12x system is that slower than HG-X ?

In term of gear change speed, I feel no difference to be honest.
Just as quick as 11 speed.
But I feel the gear change is snapier. Maybe because the hyperglide+ effect as this time I use full shimano 12s groupset (RD,Shifter,Cassette,Crank, Chain).

Thanks for sharing. Because now I need a groupset and suddenly saw a lot 1x12 Deore in the market now. Price seem ok.

I think 12 speed drive train all still made in Japan. Below 12 got Indo and china made.

If you want to save a couple of gram, you can opt for Deore M5100 11 speed with 11-51T. Still have pretty much the same range as 12 speed and still made in Japan.
Bonus is, you dont have to change freehub as this M5100 cassette still using the good old HG freehub.
12s shimano cassette use MicroSpline freehub.

Haha... correct. But 4 and 5 series Deore made in Indon now. Can not find any 4/5 series made in japan in the market now.

12 speeds RD and shifter now almost same price with 11 speed (46T) and cheaper than 11 speeds (50T). Hub I not yet build, so only will buy freehub (HG/MS) after I pick the gear(10/11/12) first.

Some more dono want to use shimano cassette or sunrace cassette since sunrace last 2 cogs are aluminum.

Short answer is cost. Shimano and SRAM both have entry level 12spd groupsets that bike manufacturers can spec for the cheapest bikes. It's more attractive to customers looking to buy a new bike because 12spd is the latest tech. Similarly, anyone can now upgrade to the latest 12spd groupos for the same price as the previous 11spd groupos. Just very normal marketing and sales tactics to get people to buy/upgrade.

I see. No wonder suddenly so many 12 speeds spare parts out there with attractive price some more.

The whole industry has moved to 1x now. 2x/3x groupsets is almost obsolete. Even the XC bikes are all 1x. Because of the big 50t/52t cassette, range is not a problem anymore even for flats. Just need to get a bigger/smaller chainring to suit your usage. Makes it a lot easier for beginners to learn how to shift as well since there is only one shifter to deal with.

actually for me, from 3x to 1x system is manufacture cut cost and reduce the material they use but keep selling the same or higher price. Some more can eliminate the old bike and force people buy new. They do like what electronic culture do. With no backward compatible anymore. This very significant when shimano introduce the MS hub.

Oh really? Maybe the early batch only made in Japan.
If you dont have the hub yet, just go 12s lah.
Yeah, for sure the sunrace cassette is lighter.
Shimano cassette all steel, heavier but more durable I guess.
I have SLX M7000 RD with sunrace 46T cassette on my XC bike. So far no problem.
Sunrace quality is good. Specialized use them on their bike.

Yup, Simple to maintain summore.
1x all the way!
