why not just get the pikes 3x3 ? no need mod here and there.

Actually, im considering new bike as well, just out of budget. 

either targeting new trifolds, > RM2.5,  or used bike RM1.5 or below. cant decide.

Hi, anyone using Nsk VV BB ?

Any comments ?

Thank you

hi Sir, actually m considering an used Oyama trifold with 3 speed internal hub. haven pull the trigger yet. in dilemma due to 'limited' speed, afraid it will be 'backward' from my XDS AFB320 (16 speed). 
If i ever pulled the trigger and in future discover difficulties to 'climbing hill', add the crankset, adding to double will make it 3 x 2 speed, just like the pikes (6 speeds) rite?

Cheers.

thanks for all input. really appreciate it and learning at the same time.

Any user's feedback on Trinx Flybird 2.0? 2x8 speed, same as my XDS, but light weight around 10kg+-. Used unit at RM1k.

...2 (42T & 52T) x 8 (11T-25T) speed consider more than enough for leisure ride rite? if wanna improve the 'climbing', change cog to higher eg 32T? or to gain better speed, change to higher chainring eg 56T? Sorry for the noob questions.

if a bike is standard specs, what are main and immediate 'upgrades' to consider; wheelset (rim & hub), crankset, tyre, and follow by light weight accessories eg seatpost, handle, pedals,...

i dont know flybird using 406 or 451 wheelset. too my folding bike in the market nowdays.
but
consider it as 406, maybe u wont get enough gearing on really tough hill like mayor/tunku with that gear ratio.

my advise,
change ur 2nd chainring to 39t
or
change ur casette to 11-32
both will do
for e, that setup is enough.

wanna go fast?
how fast?

speed for less than 30kmh (maintain)
learn how to cadence, 52t are enough

speed for less than 40kmh (maintain)
extra cadence or up to 54t

speed for less than 50kmh (maintain)
extra cadence or up to 58t

and the biggest upgrade for ur bike, is the thing that rolling the bike!

Flybird 2.0 is 451 wheelset. So, to have good gearing for climbing, change the cassette to 11-32. i think the existing is 11-25.

i dont really want to go fast. just for my understanding and knowledge.

Thanks for your input.

get 406 bike better, more tyres choice

happy upgrading! 😆
since he got 451 bike using disc brake, why not buy another wheelset size 406? cheaper than buying a new bike

i only ride one one month once these days, is it normal to find the tires super soft and in need of air refill?

Guess what, just bought the flybird yesterday evening. 

condition is very new, all seems to be fine. wheelset is 451, cassette 11-25T, will ride first and see if need to upgrade the cassette and others. Happy for now.

my XDS AFB320 wheelset (stock, with Quandro sealed hub) is 406. cassette is 11T-28T. May can swap some items...

besides more tyre options, why 406 is preferred? better in which area?

comfort depends on personal preference. good tyre give u good rolling. and all tyre need to fill with air
both tyre can swap anytime if the disc are the same dimension.

the 406 wheel give u many tyre option from maxxis, continental, vittoria and even schwalbe besides easy to find tubes.

the 451 in other term give u better rolling, much faster feel

but yeah.. i just feel like mine lose air very fast

For 1X single chainring setup, how to achieve both close ratio and wide range gearing?

the easiest way of course is to adopt 11-speed setup like 11-32T, then you will have 11-12-13-15-17-19-21-23-25-28-32T.

but what if you are in 9-speed setup?

if you use 11-32T, then your ratio would be 11-13-15-17-19-21-24-28-32T, then you are missing 12 and 14T.

1T difference in small cog makes bigger speed difference than 1T difference in big cog above 19T. not to mention your cadence higher on flat and that will make the speed gap larger and cadence lower on climb and that will make the speed gap smaller.

let me show you the calculations based on 349 wheelset on 54T chainring and 406 wheelset on 48T chainring:



at 80rpm cadence, 12T jump to 11T there will be 2.55km/h difference while 13T jump to 11T there will be 4.71km/h difference.

at 80rpm cadence, 14T jump to 13T there will be 1.85km/h difference while 15T jump to 13T there will be 3.46km/h difference.

any gap larger than 4km/h will be very noticeable.

then how to fill in this 12T gap while you still want to use 11-32T 9-speed setup?

you can learn from bro azam that combine 2 set of cassette.

in 9-speed 11-32T, 28T is kinda optional if you always rely on 32T for climbing.

at 80rpm cadence, 28T jump to 24T there will be 2km/h difference while 32T jump to 24T there will be 3.51km/h difference.

at 80rpm cadence, 24T jump to 21T there will be 2km/h difference while 24T jump to 19T there will be 3.69km/h difference.

you can combine 11-32T with 11-23T and form 11-12-13-15-17-19-21-24-32T or 11-12-13-14-15-17-19-24-32T or 11-12-13-14-15-17-21-24-32T.

if you want larger 34T, you can combine 11-34T with 11-23T too and form 11-12-13-15-17-19-21-24-34T or 11-12-13-14-15-17-19-24-34T or 11-12-13-14-15-17-21-24-34T.

this is same theory like how shimano introduce their megarange freewheel/cassette during 7 and 8 speed.

this is how 11-12-13-14-15-17-19-24-32T looks like:


p/s: not all brand cassette are combine-able, some you might need to drill the rivet screw off or break the spacer to have space to dremel the rivet screw.
