i've read Dahon Jifo 16 parts upgrades since this was quite similar with what i'm planning, and a lot of the questions i have were answered. but i'm still thinking of going through with the changes on the bike not unless from this thread i'm convinced otherwise. i thought it would be better to just make a new thread so here it goes...
i bought the jifo new but i haven't seen it personally since it's back home in the philippines. i'm working abroad but will be going on vacation sometime this june. i've about 30 days tops so i'm just gonna squeeze the bikeshop time and DIYs in my busy schedule with my boyz. after that, it'll be packed along with my other stuff when i fly back to dubai.
anyhow, most on my wishlist are for lightening the bike, but i am also changing the front caliper if there is a better one. i only wish i can upgrade to a 2-speed or better drivetrain but from what i've been reading the frame's 76mm OLD just makes this close to impossible.
the stock caliper looks like a side pull; it doesn't look like a dual-pivot as what's said on dahon's US site. from the pictures my friend sent me it looks like a long reach bmx brake but i can't really be certain. reason i want to change it is because i'm more comfy with vbrakes which sadly dahon only saw fit to mount on the back end of the bike. so i'm probably left with changing it to a dual-pivot granting it will perform better than stock. i will be considering changing the stock pads if it helps. so... can anyone tell me what reach dual-pivot brakes should i be looking for? tektro r559s perhaps? i wish i can mount road tiagras but clearance might be a problem.
on the crank, i'm thinking swapping in a crank with an integrated bb. cost is an issue so i'm looking for some used ones back home. i'm thinking i maybe able to shave off some weight from the stock square-tapered bb since from what i know integrated bb's are much lighter. trouble is i can't find info on what size bb shell the jifo has. the chainline if possible, too. i can't mount a chainring bigger than 39T cause my friend said there is very limited clearance for the chain to accomodate a bigger one. pedals will have to be replaced if i change the crank.
what size chain does the jifo use? can i use lightweight chains that looks like kmc's x9sl?
on tires not so sure cause this is gonna cause more weight on the setup. my jifo came with kendas 16 x 1 3/8s. i like the looks of schwalbe kojaks but i think big apples would be better for me. trouble is will it fit the frame and fork? this would be my first time to ride a 16in folding bike... and i don't really know what to expect. i had a chance on a used curve d3 but the weight and folded size made me decide on the jifo instead. it hardly rains here, and i have no plans of riding in the rain either so the stock fenders are going off first thing i get my hands on the bike... not unless my friend already beat me to it.
seatpost... i'm not clear whether it has a 30.0mm seatpost based on the global site cause thor's listed it as 30.4. i will be checking the weight of course so if the difference isn't worth it then i'll just keep it stock.
what's the clamp size on the handlebar? no bullbars or such... just straight same as the stock bars but i'm looking at carbon options.
hopefully, the big apples if it fits will add just the right amount of weight i'm able to shave off from the other parts.
i don't need a fast bike, but weight is a major issue for me. whenever possible i'll be wheeling it along via the saddle when folded... but i will be carrying it at times no doubt.
folded size is too since space here comes at a premium to someone like me who works here in dubai. i'm limited to walking short distances and no heavy lifting. i love cycling so much but for reasons too many to mention my options are few. there are folding bicycles here i can afford but those are just not worth the money imho so i thought it best to bring my own rig from back home.
hope to hear from you guys.
safe riding. tia.
