Ask a Bicycle Question - Part 6

[Nemesismaster]

I stay cck. short rides usually go to lck thru the old lck rd home team academy there then lck road then u turn at the end of the road runway. weekends usually mandai to yishun dam to punggol park. if more on will go to ecp then barrage, gbtb then west coast road to woodlands road back.

Oh I see u going reversed route of mine. May I ask after the fire fighting center , at the Bukit Batok junction there's no right turn to LCK correct? How ? U ride further up or u use the pedestrian traffic?

Use the pedestrian path would be a lot faster to turn right. Else if u want to stay on the road turn left to bukit batok side then u turn lor.. slower vehicles that way

Apparently, these have "raceguard protection belt" as indicated in the schwalbe website but can't even withstand a 3mm glass shard.

I believe that that's among their lowest level of protection. LOL!

You need to read the product description more closely.

406 wheels expert pls advise.

I am looking to further reduce the weight of my foldie by changing the tyres.

I am now using kenda ksmart 20 x 1.25 which i cannot find the weight online.

At the moment i am only comfortable with 1.25 width. Any narrower will be a tough decision for me. As far as possible i do not wish to use kojak since i don't always ride on road and sometimes riding on patches of water.

Do let me know if there's any lightweight options. Thanks

I would suggest Duranos but these are lightweight, high mileage tires.

No point reducing weight of yr tyre, not gg to give u much savings. For weight lost, ppl normally target to wheelset, handlebars, seat post, saddle, pedals and etc.. Reducing on accessories also help too

If I went from my current Marathon Pluses (700+ gram each) to Duranos (190 grams each), I would save almost a kilogram in weight.

TS dont wish to reduce the tyre width

 

[Sadisticnoob]

its a size 48S, top tube is 52cm. Nope to the bike fit, want to do a test ride before I decide whether a fit is required. no plans to sell my tyrell and brompton, although someone is interested in my tyrell.

Spend so much money should do bike fit ma,

Haha okay Lah..I 63-65kg only..One thing I concerned also is durability..maybe need erwinrommel comment about kinlin. Haha

I think okay to use

But one thing I don't like about lightweight hub is that they use small bearings

My litepro s42 cmi very disappointed for that price, had to redo the valve hole so that the inner tube can fit

Actually 1.1 vs 1.25 got much difference in safety n comfort?

after fire station turn right to bricklands rd then all the way up to old lck rd home team academy there. I usually cycle on road one.

yup... narrower = faster

 

[DigDub]

not necessary. nowadays cyclists prefer to use wider tires as it has shown to have lower rolling resistance. but the rim also needs to be wider to make wider tires effective.

General believe narrow tyre have lesser surface hence reduce the rolling resistance, the psi also play a part to the resistance but compromise comfort. Comfortability is of cos everyone's preference.

Chorus used to be the best value buy from Campy.

most cycling websites that test rolling resistance generally find wider tires roll faster, for eg the very popular continental gp4000s II tires.

it's explained quite well on Schwalbe's website:
http://www.schwalbe.com/en/rollwiderstand.html

but the rims have to be wider to take advantage of the wider width of the tires to make it effective.

nowadays most bicycle manufacturers and wheel makers are coming up with equipment that can take up to 28mm tires.

 

[azz909]

My current wheels are 23mm wide and I use 25mm tires, because of the wider rim I roughly guess the tire width are about 28mm now. And I can say I don't see any difference in speed compare to my previous more aero wheels with 23mm tires. In fact going down slope its even faster And on some rough roads it absorbed the harshness well. Quite happy with the wider is better approach

Fatter tyres heavier and slightly more prone to wind resistance?

actually 25mm is equivalent to 1 inch.. so it isn't as wide. Before I got my road bike, I thght these tyre are wider, only to find out, they are the same as those 406 and narrower. The thinnest tyre I had on my Tyrell was the Ultremo/ One series at 0.9 inch. Compare to the Durano at 1.1", should be a 28c on the roadie.

for small wheel tires I think the wind resistance penalty not as bad as bigger wheels. and tbh, I think most of us are not that fast enough that wind resistance on wider tires becomes an issue.

I'm using schwalbe one on both my foldie (0.9) and road bike (25mm). I think the road bike tire is wider by a bit. but anyway, I think rolling resistance is just a small part of pedalling efficiency. most important is to enjoy the ride.
