I did see news of the exact same type of situation in SG before about a year ago. a girl went into a spin class and had the same problems.

As long as we understand n listen to our body...
Know whn to stop when it is too much to handle...

We will be good...

Normally ppl who wana proof something will push themselves to a zone which beyond comfortable...

well, cycling on the open road does force us to be a lot more careful on a lot of things...

where a spin class indoors with a/c on and music blasting is kinda different. this is likely when they got pushed beyond what's safe for them without even realising it.

but like the similar case in SG previously, I do have some questions on how exactly this happened.

I would have thought that the person would have bonked out before they managed to get their muscles into such a state. or at least black out the moment their HR drops when they get off the bike.

possible that the instructor push them too hard.
not know they are already at the peak.

i join these ride class before, so i have first hand experience also.

Saw this while riding in klia today

owh?! you were there also?
didn't know the owner then just managed to took the photo from behind then chow

Dafuq aerobar like that?? Lol


Nice megabike customs

I was at mcd when I saw this...
Haiya... Next time go klia we should ride together...
I normally start riding at 7AM

Ikr, wonder how does it felt to ride like tat...

modern tt bar, wanna look at the road need to look in between forearms haha. but its aero for many types of riders, so it works lol. hands close together with elbows open chest more space to breathe also I guess. old bike had traditional tt bars, wasnt the easiest to breathe, needed shorter crank arms so my knees dont go all the way up to stomach lol.

anyone got ride plans tomorrow or wednesday?

Yeah when my knee touch my tummy, always reminds me why I m cycling at the first place... Haiz...

Need to keep my weight down so can ride 30km/hr...

Hanging bike til wed

Hi guys….. what tyre would you rate as good.
GP5000? P-Zero?

Goodyear F1 pretty crappy right ?

Looking for a change

I used to have Conti GP5000; very fast tire with lower resistance but very harsh at high pressure. Excellent for racing.

Now i use Pirelli P-Zero for commuting to work; not as fast as GP5000 but still faster than than normal Conti Grand Prix or peformanced VITTORIA tires. The reason i uze P-Zero because its very comfy pillowish feeling on 100psi air like riding on smooth road and very grippy during cornering even on sandy patch. No road buzz. Feels more confident handling my bike with this tire in slippery traffic at high speed especially in heavy rain or green mossy patch of roads.

Both almost same priced but if you wanted to win a race go for GP5000 but if you want comfort with grip and performance in wet condition go for P-ZERO. Have not use Good Year F1 yet so no comment on that.

Thanks for the comprehensive tips.
GP5000 seems very soft and quick wear off right.

Me not going into race, but do appreciate a little bit less resistance in ride to save me a few watts.

How about Swahlbe?

As for better balanced tyre for more comfort and puncture resistance- wat would u recommend ?

Both GP5000 and P-Zero worn out quite fast. I've change a pair once a year because thinning of rubber and the lining already show some cracks since i ride a lot under the sun 4x time a week in a year.

I can't say much about Schwalbe on road bike tires but i have an experience using it on Mountain bike. They are very grippy tire but the worn out twice faster than the other two as long it carry that 'race' or 'racing' labels. However they also made the toughest puncture resistance road bike tire the 'Schwalbe Marathon' popular among daily commuter but slow and heavy.

But in malaysia market the best tire for well balance both comfort, performance and puncture resistance is Pirellli P-ZERO Velo 4S. A bit heavy than normal P-Zero but beefy...good for rear tire setup.
Just stay away from MAXXIS brand, my 15 years of puncture, skids and crash on this tire....but they are cheap.


Here's my summary experience about puncture during my commute to work on road bike (700x 25c):
---------------------------------------------------------------------------------------------------------
CONTI GP5000 = 1x puncture in 1 month (Glass, thorn and sharp metal puncture)
PIRELLI P-ZERO VELO = 1 puncture in 3 months (only sharp metal puncture)
MAXXIS RE-FUSE and other models = 5x puncture in 1 month (Snake bite rim, glass, thorn and sharp metal puncture)
VITTORIA RUBINO = 2x puncture in 1 month (Glass, thorn and sharp metal puncture)
---------------------------------------------------------------------------------------------------------



Note: Here's my Schwalbe tubeless ADDIX tire with steel nail stabbed inside keep riding like this for 3 weeks.

I personally find that Schwalbes tend to wear out faster then GP5000. And not as puncture resistant too.

But having said that, there's also ppl who swear that they never puncture on a Schwalbe before. I guess it depends on the individual's luck too.

used schwalbe one (not pro one) before, quite durable and reliable, not the smoothest and wet traction also not the best, but overall satisfied. have yet to try gp5k, dont really like conti ever since my gp4ksii had a cut that expanded until tube poked out, pretty weak casing I think. used pirelli p zero velo, michelin power competition, vittoria corsa g+ 2.0, would recommend either of those too. I dont ride much so most last about a year lol

hi sorry new account due to i unable to login with my old id somehow, dont know what happened to lowyat net.

i looking to buy a road bike, but i found that almost all the bike are out of stock, giant bmc trek very limited model and size to choose, merida specialized totally no stock at all.

also, i found that the price had increased significantly, about 15-25%.

i m not really keen on polygon and china brand, so i start look for used bike.

then i noticed some strange thing in fb used bike group, carosell and bicyclebuynsell.

there are quite a number of branded bike like bianchi, specialized selling quite cheap, 105 groupset selling at 4-5k, seller said that condition very good 95% like new hardly used n lots of reason.

then i ask where u bought it, most of them said bought from friend or sell on behalf of someone don’t know where the bike came from.

i ask for receipt or proof of purchase, and out of almost 20 sellers, not a single one can provide the receipt.

is that normal? cyclist in malaysia don’t keep the receipt at all?

or is that something fissy there?

I m closed to the bike shop tat I dun keep the receipt.

105 gs... 4-5k consider not bad for second hand...

Best u see the bike with ur eyes before purchasing...
For any defects...

If ur concern is oem bike then u better snap pics and show to the world to help verify...

if merida/giant/java/twitter I wouldnt mind, not many counterfeiters bother making those brands. if pinarello bianchi cervelo specialized trek bmc colnago rm4-5k I would ask for receipts.

pinarello pricing damn crazy nowadays, the 2nd tier prince full bike already rm30k+ lol.

i owned 3 Cervelo..
aim for their off season bikes from the retail shop, it drops quite significant.

30k bike can ride 30km/hr anot ?
