Ask a Bicycle Question - Part 5

rolling resistance lor. actually anything that rolls properly, weight doesnt matter much.

Weight will kill me when I accelerate from 0 and also when upslope, right?

But how about in terms of long rides of 40km n above? Weight will be a great disadvantage but can easily overcome by better rolling resistance?

My long ride usually on pavement with human traffic and also many traffic light stops.

Need to strengthen your legs at the gym and do some long distance running. cycling alone is not enough

You should be able to get it for about $65.

For most local guys, you should get the GP3-S, not the GP3-L. Remember to check which type to get depending on whether you are using grip or trigger shifters.



Only Brompton will have a problem folding with GP3 and above (GP4/5). More specifically, Ergon GP3 and above fitted onto M/H/P bars will scrap the ground during folding. S bars are ok. I am using GP3 on my S bar.

If required, you will have to ask the bike mechanic to cut the griips for you if those are too long.

GP2 to GP5 difference is the length of the flaps, or the wing piece as we call it.

The wing piece is useful when cruising or climbing hills, and provides numerous palm rest positions. I personally recommend at least GP3 and above. I haven't wear gloves after installing Ergon grips. In fact, I was the only one who didn't wear gloves during round island rides cuz I installed Ergon grips.

What is amazing is that even with sweaty palms, or when its raining, the grip is still firm enough and won't slip off.

As for size, its simple. Unless you wear thick gloves during winter (which is non-existent here), just stick to S instead of L. e.g. GP3-S, GP4-S, GP5-S.

And if your bike uses trigger shifters, just use the longer version. If you use grip shifters, you will need to check which side is shorter. Or if you are adventurous enough, just cut the grip and then use a lighter to burn away the burrs.

I always tell people who first buy folding bikes to change their saddle and grips if they are feeling uncomfortable. Everyone who has tried my Tern and Brompton bicycles have all changed to Rido saddle and Ergon grips.

The ergon nexus and gripshift cannot be found here. Have to order online. Correct me of I'm wrong.

Thanks for the info guys. Browsed some lbs sites and seems that they do not carry the GP3 BioKork version that is listed in Ergon's site. Is it even available in SG

Your wheels are heavier because these are MTB wheels and tyres. That's why you need a lot of strength because of higher inertia. If i were you, i will down gear accordingly by anticipating the traffic flow and then increase cadence once the obstruction is cleared. Only after reaching a high cadence will i shift to higher gear.

Otherwise you will need to stand up and pedal if you do e stop on a high gear.

The roads and terrain you describe are actually considered normal urban cycling. I dunno why you choose mtb over mini velo. Small wheels accelerate much faster when you do frequent stopping and accelerating. Easier to maneuver tight confines.

is it worth it to directly import a bicycle from taiwan? if yes please recommend a hobbyist a taiwanese bike/ MITaiwan around 800 -1K SGD

 

[Broadwalk]

I think get from SD shop, mybikeshop, or BRU will be better.

Why you want the biokork version?

i always choose performance over weight, becos, the heaviest mass is always the rider.

500gram = 2 mc spicy lolx

I don't think you should view slopes as something dreadful. You should aim to cycle up the slopes as a form of training. It really improves your cardio. And for every up slope, there will always be a down slope. Since yours is a MTB, you should have more than sufficient gearing to climb up.

Not to demoralize you, but during my Brompton round island ride, there's a lady in her late thirties who rode a three speed Brompton. During the slopes at mandai, she reached an average speed of 22. On normal flat roads like west coast highway, changi coastal and seletar link, she cruised at about 30-32 kmh on her 16 inch wheels three speed Brompton.

I was already struggling to catch up with her. I was cycling on my Brompton 5th gear and reaching 27 kmh... To maintain such speed on a Brompton, i used more than twice the amount of energy needed to go such speed on my tern.

But then she runs marathon, cycles thrice weekly, and always go for sports events. I think some ppl may know who i am referring to if they cycle seletar often. But then she has tyrell and road bike as well.

So it's all about training, mindset and mentality. Distance is just a number when you are enjoying yourself on your bike.

Most importantly, ride safe and ride fun!

here's my bike, still thinking what blue things i need to get.

why no use cleats

 

[Cryogenist]

My 700c tires is 600g each. Pretty heavy comparing to race tires.

But, rolling resistance, puncture resistance, durability are a few notch higher.

Don't really need to worry anything much for the tires.

wah those pedals..... nightmares of getting cut pops up in moi head

 

[Jay Bee]

sian raining again

 

[Sadisticnoob]

I changed tires to better rolling resistance but per wheel becomes 200g heavier than before. Which would u prefer? Weight vs rolling resistance.

the one that doesnt punctures

i really kind of scare. i see my friend with broken hand after falling.........

gotta try, trust me you will go faster within a few months

last time got syntace offer on bike 24, can customize rims color but now no more liao

no thanks, i rather go slow

Looks better to me

Should I get the Rido R2 to keep first? It's at 30% off.

I would like to pretty much get a feel on how much I like the current saddle before deciding if I should change. But the Rido R2 is at a discount due to the GSS which is ending in a few days.
