totally agree wif u...

lets get lost for more milage!

Haha...

Hi guys, new to foldie. Just got my Tern B7 during haji long weekend. Nice service from Rodalink bangsar. So after few days of riding and commuting, I'm thinking to change my crankset. Either a tiagra or litepro double chainring. Is it possible to do this without changing the RD? As I'm totally fine with 7 speed RD now and changing the whole system will be op costly for me.

Thanks a lot!

Absolutely possible. But then , this entails getting a new set of shifters, right? If you are getting a new set of shifters ( you need the left hand side shifter now ), for the possiblility of upgrading the rear in future, HOW ? My advice, get 8 speed shifters, left and right and then source for 8 speed freewheel cogs ( so, only 1 item more, the RD should be able to handle it ) Then plus the front , you are all set and no need to further do any changes unless off course, you want to.

hi sifu etigge,

is it advisable to get java fit/pro 451, 8 speed version and modified to 10 speed?
or better get the dual chain ring become 20 speed?
or don't bother to modify, save money get better bike?
how about cheaper bike like trinx 7 spd?
Compatible of original wheel (7/8 speed) to 10 speed cassette how to check?

If modify, road system or mtb system better for foldie?

Thanks sifu!

Yes a left shifter.

My cheap solution is look for a used left side shifter only or get at decathlon(Not sure how good is the shifter but i think should handle the job since it's only 2 speed).

So here come a new question,
Is it a must for 8 speed freewheel cog for 8 speed shifter? Can i use 8 speed shifter with 7 speed cog and skip the last speed?
Also the chain, can i remain the 7 speed chain since as what i reaserch 6,7,8 speed share the same chain.

No, you can't use different shifter for different specs. 8 for 8 and 7 for 7. Oh, yes, forgot about the chain. You need to change that also. I don't know about yourself but I am a stickler for perfection. When I have this on the right, I need the same on the left but if you are not , it's should be OK. In fact if you visit GW Cycle in Kota Kemuning, they sell only the left as well if you are using SRAM's grip shift.

Java is one brand that uses bike specs to promote their bikes. So, my guess is to get their best specs that you can afford. We as consumer can never get OEM components as the manufacturers can. Drawback is, for us, we know what the good components are and usually good components are those popular ones and Shimano or SRAM never sells them cheaply either unless they are the older models and they are trying to clear them, not to say they are not good. You just need to find out what's good and what's not so good.

I ususally like to start from the core. The frame ! From then on I start to assemble what components I like. USually the outlay is higher but it's cheaper in the end compared to getting one with the same specs from the branded manufacturer. Anyway, most bikers are not that well versed in the specifics of biking in the early stages so they are not as critical. If you are serious rider, you will find out later, there's no short cut either unless you are those rich wallet fellas who wants the best but under utilise the capability of the components. Happens a lot in mountain biking.

I would suggest using roadbike components on folding bikes.

Thanks for the reply. From your opinion, Java frame good enough? Or any good but still not too expensive frame to start with? Dahon?
Java latest FIT is 18 speed, which cost around 1750. Can i build one, 10/20 speed with similar budget?

PS: no rich wallet, poor man here.

Hi..

im a newbie here. just bought a TRS Victor last saturday. equipped with shimano gears, 16 speeds (2 front, 8 rear)..

but since yesterday, the chain seems to be coming off frequently, especially when I shift to lower gears..sometimes i suspect that the chain wasnt properly fitted on those gears since i hear a weird sounds everytime before the chains is coming off from it's track..sometimes it's pretty annoying..is there something wrong with shimano claris system? or are there any other places that i should look at to eliminate the problem?

help sifuss!

So in my case it should be find if i remain 7 speed RD, shifter, chain and only change my crankset and BB, add a left shifter and good to go right?
I don mind if it's different and don have any mind to upgrade further in future. This will be like my commute bike, combination of bicycle and lrt is good enough.
Just not happy with the stock crank, too much power loss and since wanted to upgrade i will just make it double chairing.

There is a frame made by Litepro and named Crius. Also there's a model made exactly like the Tern Verge. The importer brought in 3 units and today I met the guy in Ipoh and he said, it took him ages to sell the bikes. Funnily, this brand sells like hotcakes in Singapore and Thailand. If you talk to Jimmy of Kimbell Jaya Bikes, he can order the frame and maybe a complete bike with 9 speed. Don't know exactly the cost but from what I heard from the importer, the whole 18 speed bike is sub 10 kgs. Maybe keep this in mind as an option. In regards to whether it can be within 1750 for 18 speed, you can talk to Jimmy and check it out.

Also Crius also has a frame that looks like Dahon Speed which should be cheaper than the Verge version.

Too much power loss from the stock crank? Don't think that can be easily felt, maybe you meant that it is more flexy?

Anyway, a lot of these mods are done to feel good rather than any measured efficiency. Good fun regardless.

Big thanks!!!! I will look into it.
So much info from this group! Appreciate a lot!

If I would have known more when I started on folding bike, I would have just save a couple hundred more to like rm2500, and get a dahon 10 speed or 18 speed..like the MU model..and I am pretty sure it will be a better bike then the javas

is this the dahon MU you talk about? Looks good
http://bicyclebuysell.com/item/352499/daho...16-folding-bike

Initially i thought to get a cheaper foldie, to cycle to work, as RB too big to store.
Seems like better invest a bit more in better bike.
Dahon Dash, good? I like the look of dash, minivelo-like which can fold

Dahon Dash used to be a popular and a good in between folding bike but our models here are getting ridiculous! First they came our with disc brakes then reverted back to V-brakes and added a funny looking rear carrier and even worse, the importer here brought in just the 'S' size and many riders looks funny riding the small bike. Anyway it is a good bike, me being one of the former user of it but the earlier model. It folds bigger though. The MU is also a good proven bike, the dolphin shaped frame which is copied by most brands nowadays. Started off as the 16 inch Dahon Curve then to the MU 20 incher and now comes with better specs and paired with 451 wheelsets.

Now is the time to go check out Kimbell Jaya as they are having warehouse sale.

Yes more flexy and i actually can tell the different and it's quite obvious.
Compare to my ultegra or even old Shimano 600 EX crankset.
it come really obvious when climb hills/flyover.

Of course also to make it looks good la, who don like beautiful stuff right??

Hi i just bought a used dahon speed p8 yesterday.
It came with so many aftermarket part.

I just want to confirm the handlepost type from each generation of p8.mine is t-bar non telescopic.i suspect previous owner change the handlepost as well because i never seen p8 with fixed handlepost height.

Anyone can confirm?
