Ask a Bicycle Question - Part 5

[Sadisticnoob]

Actually, its the ratio of the front chain ring to the rear sprocket.. that is, the gear ratio, that confuses you.

Not all rear sprocket is the same. On a standard cassette, the smallest is normally 11T. In some extreme cases, the smallest sprocket is 9T (shimano capreo).

Simple maths... 53/11, 58/14 or 53/9 biggest? I am simplifying things.. for most cyclists (me included) can never use the largest gear with reasonable cadence.

I have personally seen 53/9 on 406 wheels charging down changi coastal. That sight, to me, is one of the most unforgettable scene in my cycling history. He overtook two road bike pelotons before disappearing from my sight. The rider is a hardcore cyclist who always ride road bikes on long distances so that's why he can sustain such incredibly high gearing.



Birdy is indeed very fast and comfortable. I know.. cuz i cycled with birdy cyclists before and i also know the birdy admin.

i never use the last 5 gears on my mini velo too roads here too flat

Hi, need your kind advice here. I'm planning to purchase a bicycle for my 15 year old younger brother for his birthday in Feb. Not too sure about the different bicycle terms here. He uses his bicycle quite often, from going to school, playing soccer and going to shops and on occasion riding at Park connectors with his peers. The bicycle he is currently using is some cheapo giant bicycle that is more than 5 years old. I guess this would be a practical gift to him. Budget not more than $300, the lesser the cost the better hahaha

maybe go with him to buy, buy what he likes as thats what teenagers are

Having 9t at the back is almost 1x faster! I understand the ratio. Big front crank drive small cog = Speed.

If the rider you mention rides a 58/9 wouldnt he be flying. :O


Maybe I will get this http://www.togoparts.com/marketplace/ad-details/876053/birdy-2015-new-model-standard-9-speed-disc

And then if I feel lacking. I upgrade to capreo hubs.

dont upgrade to capero hubs, just change to a bigger chain ring. i dont believe in using propietary technology

That is.. provided you have the strength to pedal and maintain cadence at this gear ratio 58/9. It all depends on whether the person's engine can take it.

My friend's Birdie with capreo is already cruising at 32-34kmh while his heart beat barely enters zone 4.

The bad thing about capreo cassette is that the gear jumps are quite crazy. Very hard to keep spinning consistently.

I will stick to 23-12 ten speed cassette. I am a weak rider. 53/14 on 451 wheels is already quite tough for me to handle.



One thing about capreo hub is that the tooling is different. Not many bike shops have the necessary cassette removal tool.

with training can hit 34kph comfortably, i dont ride ooften now maybe once in 2 weeks but still can ride at 40kph in slipstream if i need to . just wear heart rate montior and train. the faster you ride, the faster you get home to sleep

Thnx. So any mountain bike will do? Or?? Hmmm

you have 2 options, a mtb or a mini velo. mini velo its quite small can park inside3 house

should confront him..

now i am wondering if i should just go soft and ask what he is unhappy with?

or launch my arty which may spiral out of control.

 

[Sadisticnoob]

ask him whats his ******* problem. tell him, about wanting to go back with family and be safe I am poor no money take transport this is my transport bla bla bla.


no point being aggro

yeah, except that he may be aggro against me. I duno izzit my riding sucks, he fugging hates cyclist or maybe i stole his coy business or what

if i launch arty most likely he wun be able to make sense what/who just hit him

yesterday i knocked politely on the side window he just ignore. any tips to make him talk?

 

[Sadisticnoob]

finally my bike 24 stuff shipped yesterday ! with that I will finally be able to upgrade my raleigh mini velo!

it came from a flat bar min velo to a drop-bar kind mini velo, going to take it one step further to upgrade to current 10 speed bikes and carbon handlebars since my sweat tends to corrode aluminium handlebars.

its been a blast riding this bike, riding 2-3 round islands with road bikers, its heavy and stable, but the wheels are seriously a let down

will be chopping off the 4cm or so from the steerer tube for the confirmed position and hopefully clean up the cabling to make it neater.

full upgrade list, hopefully it will be done after CNY so that I can proceed on to my next project (project 6.8kg road bike)

make him get out of the car and talk lor. next time need gpgt put video camera on bike liao.

this kind of drivers quite common, they dare to be aggro with you but when stop and confront they go back to being a ****y and scary cat

You power rider. I am still hovering about 30kmh, with the occasional sprint at about 32kmh.

Normal will be about 26-28kmh (smell flower ride).

Ya...I am for putting cameras on bikes too. The more the drivers are aware that there might be recorded evidence, the better. But till now, I am still finding cameras with battery that can last at least 4 hours or longer.

hmm, i thought about it use a camera that can record under external power then use a powerbank, put it under the saddle or something.

just ride hard, can become faster and faster. it helps that I had 2 coaches who taught me to ride better.

my coach always tell me you wanna ride fast have to keep riding at that speed, if you ride at 40kph you always think those riding at 50kph is fast and so on.

I've got 2 cameras, one front one rear. But both the batteries can only last ard 2hr currently, noted during my ride couple weeks back. Now trying to find out if can replace the rear fly6's battery as it is built-in internally. It's been used for a couple of years already.
