The other one is Polygon but I rarely see them these days, even in Rodalinks but you can try to find out
Polygons used to be really value for money, until they decided to raise their prices. For the current price, most people will prefer to look at other brands.

Some of you probably seen this before. Quite an old frame, but components replaced since the last time I posted this bike

been using campy from the start?

First incarnation was actually Ultegra, taken from my previous Polygon frame. Switched to Chorus, then finally SR 2 years ago when the 11speeds was on clearance sale.

so shimano vs campy, mana u syiok?

I actually prefer campy, but having said that, I'll likely only buy campy if got clearance sale lor.

Even when comparing DA9000 with Chorus, Chorus has better precision, and tuning hardly ever goes off. Although DA is lighter and smoother to shift compared to Campy.

never have i destroyed tyres as quick as the contis.
my gatorskin koyak after 100km
brand new gp4k sidewall koyak on its first ride, the first 10km
its price was the most expensive back then
u can google about contis infamous sidewall
dare i say, even more fragile than jbcoders hati tisu

Continentals does have this problem previously. I remembered a stone flying from the ground because somebody rolled over it hitting somebody else's sidewall and cutting the GP4000 sidewall. I recalled you mentioned that this happened to you before too.

But I started using them again from the GP4000S2 and now the GP5000, never had any issues with the sidewalls anymore

Yeah. never happened to me, but I've seen it happen to others on a few rides before. but Continental fixed the problem with the GP4000S2 and after.

Vittoria Corsa Graphene? I remember the early batches of these had manufacturing issues. Seen a few cases where you get a nice clean up to 1 inch split on the sidewall, especially after hitting a pothole. Later batches had this fixed though.

On the topic of the cycling computers, does anybody use the Garmin speed sensor? As in the one that attaches to your hub? Do you get problems with frequent disconnections? Tried on both front and back hubs, also the same problem

Used the cadence sensor (attach to crank), and the 2 in one speed+cadence sensor (attach to chain stay) before, and never had this problem with these 2

I tried with magene speed sensor to Wahoo head unit.. there are some intermittent disconnection too where my speed being shown as 0.. after that attempt i never use speed sensor anymore, GPS is good enough for most of the time..

Never had this problem with speed sensors that goes onto your chainstay and a magnet on your spokes before, so this is kind of annoying. Looks like I'll go and dig out my old speed/cadence sensor and use that instead, although it don't look as tidy.

maybe i been chanting HTFU for so long ady until my hands become badass dy
or i ride too santai and avoid rough surfaces haha

whatever it is, i've used diff types of bartapes. from thick to thin. cork/foam to gel types.
these days even bartapes are priced ludicrously expensive. i'd choose something less than rm100.
*
I find that proper fitting gloves makes more of a difference than bar tape. 2XU and Rudy Project gloves fits best on my hands (skinny fingers), but they also both now discontinued their gloves sad.gif

otherwise other gloves I tried I do notice my hands can still slide inside the gloves, and its that abrasion that causes the problems.

I honestly do not fancy custom built wheels as I have heard of many tales of spokes breaking but it can happen to any wheelsets, even ENVE so I am just not comfortable myself.
It mainly comes down to how well the spoke is tensions when the wheel's built. Went through 3 pairs of custom wheels so far, only one of them had a spoke break, and that's due to it the tension being too high.

Chris King hubs + spokes

Im not 100% sure what is the real retail price but 3-4k is the ballpark figure based on what I know

ah ok, I remember the hubs without spokes are roughly 2.8k the last I checked

try it. lower from 110 to 80 & go for a ride to kundang. you'll be shocked!

the theory is supposed to be that narrow super high pressure tires causes a lot of bumping around when you're on the actual road itself, and this contributes a lot to power loss.

I reduced to 90 PSI from 100 on a 25c (my rims are 21, so the tires actually look like 28), and noticed that there's less effort to maintain speed

Good as in better rolling resistant? At lower pressure ?

I would thought pump to 100 psi is stiffer. Stiffer not so comfy but suppose to roll better eh?
*
That's what I used to think too, pumping up to higher pressure means rolls better, but apparently it isn't that simple.

I tried a lower pressure (93 psi @ 25c on a 21mm rim) and to my surprise, I actually find it easier to maintain higher speeds. Went to google more about this, apparently the explanation is that power loss occurs whenever you are bumping around when using tires with too high pressure too. It can depend a lot on the road conditions. If you're riding on a surface as smooth as an indoor track, then probably won't get the same bumpiness as you would for normal road riding.

Definitely do not want a too low PSI, but also don't want to just pump all the way to the max too.
