ugo much better la... the wheelset & build quality.. n QR

just lucky lah they all active in community,just join lah together we unite

anyway,
if upgrading ur gear set few setup might consider if upgrading to 9speed and above casette
wheelset hub
since u said previously ur bike is 6speed,its a must to change ur hub or got bigger budget better switch whole wheelset

since u said u wanna get 8speed,
the budget is not that much coz casette for 6 to 8 speed are lock type (1whole casette system) and 8 to 11 speed are casette type and can change the ratio

few items to consider to change if ur bike only 6speed.this is maybe the lowest tight budget for upgrading
but if ur on more tight budget,
i suggest u change the crank only lah.shifter and fd no need lah,coz u can manually stand ur bike and pick the chain and drop to what size u want.like my dahon vybe,im using shimano sora 50/34 but with no fd.incase i need to use 34t,just manually drop lah

fb page takde,tp dia create group,.

oh,
u already into fb ipoh foldies.didnt notice that,sorry my bad .
shah alam also can maa,..just start 1st then the crowd will come later.we all start in a small group 1st,then people will notice until now

btw,
the best and effective upgrade is ur crank.from 6speed u can get 12speed or 18speed only from crank.but if u upgrade only the casette,u only get from 6 to 10 max...so why bother to get the casette?

the link above sell crank for only rm70.u can get 18speed with the crank.for me its worth it lah event without fd,its not a big matter to me.i already using shimano sora 50/34 on my vybe without fd.already achieve to climb bukit berapit (up north and down south) without "sorong" the bike with those cranks (on the way to taiping with 50-32 and on the way back cannot tahan already with gear setup 34-21)

p/s :- sorry,i didnt mean for show off,but its a good & true fact when upgrading ur crank will give u better gearings

now pepatah melayu always said
tepuk dada
tnya selera

got money then go the upgrades u want.no problemo! bydaway, u can get new 6speed alluminium folding with those budget also depends on ur valuable and memorable bike lah
couldnt agree more on you bro!  

i will upgrade the crank 1st and later with cassette if i were u radiohead... if u got crank size 30t why bother want the casette size 34t?want to climb a coconut tree ka

Hand itchy. So bought Amis Folding Bike - 21speed
