It's quite ironic isn't it! I mean we buy a foldie for it's folding capability so the bike is brought along all the time. Why lock it to a post?

I saw your bike the other day. It can be upgraded to double crank, why not? You just need adapters for the FD. I got a friend who even upgraded his Kalaq to double cranks. Here's another Dahon Eco C7 for sale.

P/S. You have to used FSA cranks specifically. There are Shimano Sora or Tiagra and from Shimano there are even the 2000 series which is even much cheaper. The reason why we upgrade is because we want more range in the gear inches but if you are going to change FSA single for the original, there's no advantage except for the weight which I don't think is important for your Ugo.

It might be a square tapered one and you don't have to change the BB as well. The rest can be used provided that your cranks are not abused. If it was used for too long the chain might need to be changed but this comes only after fitting and see if there's chain slip. Looks like a nice crank and rings too.

From China worr! What happens if arrives here, it is different. It's a good buy if what they describe is as it is. I have look at your Ugo the other day and I am sure the FD can be done but then again it not worth your while to upgrade, might as well get a better buy. Thing is, your prospective future purchase is also an 8 speeder only worr, no double crank.

I think you should check for Hasa Minimax in Bicycle Buy Sell. I think there's still another one, trying to sell for RM1.3K. Maybe you can negotiate for lower. Should be good for you. No need to upgrade and all.

I think earlier than that. It was bought for 2.4K, if I am not mistaken. He has two and moved on to road bikes. He sold the red one, only the blue one left.

There no point going backwards. If speed is what you are aiming for, then change to road bike cogs at the rear. Increasing the cogs in front will increase speed at the expense of harder pedalling. When it comes to uphill rides, you will be without the lower gears!

Adrian,

A friend posted me this photo. a modified Raleigh Ugo weighing only 9 kgs. It belongs to a friend of his.

There are all kinds of riders, rich, poor, strong, weak, but most important is they ride. There are some like our Mr.Samo who is a purist. Means he buys bikes that are have already satisfied his requirements or fancy and once bought it stays that way. Only maintenance, nothing else. There are also riders like CCLEM and myself included. We like to tinker and go round bike shops hunting for parts for modification. Apart from the riding that we love, the upgrading and tinkering is also a hobby inclusive! Apart from filling in the requirements that is needed in our rides it also enriches our skills in repairing which is very important as well in rides, especially long rides. I even carry a spoke wrench in my saddle bag apart from the mini tool and spare tubes.

Just like my Eco C7 which is an entry level Dahon, I have already upgraded to the max already. I feel satisfied with it and a few weeks back, I was actually looking for another bike. Good frames, good components, SUPER expensive! Good frame, mediocre components are also quite expensive and eventually the components are going to be left in a box unused, like my 2 Eco C7 parts. Finally, nothing like my old Eco C7, which is a good frame ( I have bounced on it, went downhilling at 50 km/h with confidence ) and now it's a 27 speed. The nearest that comes near it is the KHS 27 speed which cost over 4K. Dahon MUP27, although 27 speed , I don't like the internal gear.

Upgrading also makes buying a bike to your spec, easy going on your pockets! Just be sure it's a good frame and keep on adding. My total cost for the Eco C7 has already gone beyond 4K already and it took me almost a year. My wife's Eco C7 is 24 speed and my daughters Speed is also 27 speed. Seriously, if you want to follow this path, it's better we learn to do it ourselves! Bike shops has no time to upgrade it for you. The first time I wanted to upgrade to 8 speed from 7 speed,(I don't have tools then) , a bike shop in Bdr. Mahkota Cheras adamantly told me that it cannot be done. Now my bike is 27 speed! See how good some bike mechanics are!!! There's another one even worse in Damai Perdana. Once I bent my V-brake post and he told me it cannot be sourced and ask me to change bike

Another point to consider is warranty. Most bikes won't retain the warranty once modified.

There are 2 screws side by side on the FD, for that matter also on the RD. They are the limiter screws for maximum internal and external travel of the FD. You need to limit the travel so the chain won't fall off the chain rings.

Very seldom used! Just want the option to be there when my butt is painful and just want to pedal lightly.

Just walk into a bike shop and ask around. Then you buy one that you fancy and join your friends to ride. After a few rides, you will get the idea and also will come to an opinion yourself and then on you will know the answer. I say this because, IRONICALLY, when someone ask, we answer but the advise is never followed. Hahaha! When they walk into the bike shop, let's say, we advise, buy a Dahon or a Tern, which are a good choice, reputable and dependable. In the end they come out with XDSlah..... Trinkslah....etc...etc. Why? For one this bikes gives a better return for the shop and also the shop can easily convince you because of the higher specs in components. I mean, let's say, entry level a Tern cost RM1.3K for a 7 speed but for an XDS the same price can get a 16 speed Shimano gear!

Frankly speaking, all bikes can be ridden. It's just a matter of how long can one use it. Some are made to last while some are made just for the moment and this means a few years. I rode to Fraser's Hill on my Dahon but at the same time also I see other rides up with a Kalaq or XDS. Both can reach. What I am saying here is.......... just buy anything you fancy. Most serious bikers don't stick to one bike, they form an opinion by themselves when they join rides and see other riders' bikes.

I think you can find 48T (but alot of 44T though) mountain bike cranks and they are cheaper too if you are not choosy about level. Off course if you want Deore or higher it's more expensive. You just need to take out the other 2 rings. Also many are upgrading and you find a lot of used ones in Bicycle Buy Sell. There are a few riders in this forum that organizes bike rides. Just keep a look out in this thread.

If you already have the crank, just hunt around for the chainring. Shouldn't be hard to find. Just make sure you buy the ring with the same PCB.

Actually a foldie is more comfortable to ride than a mountain bike. You can actually ride seating yourself upright. Wheels are smaller so less resistance, easy to upkeep but slower lah! Anyway we are not racing anywhere. I am hovering between 98 kg to 103 kg and I have been riding my Dahon Eco C7 for the past year! No problems whatsoever.

If you are using a 20 inch bike, you probably can use the XTR RD but the cage is too long for a 16 inch wheeler. The XTR crank can be used but you will have to pedal faster (which is more tiring than riding hard) because of the lesser number of cogs on the crank. A 16 inch usually needs a 53 to 55 teeth on the crank but MTB cranks maximum is 44 cogs only. You already have an 8 speed setup, changing to the XTR will only increase another extra speed Or maybe I don't fully understand your question. Are you changing the whole groupset? Or just the crank and RD. What's wrong with the Sora anyway? If they are road bike cogs, changing to MTB cogs will also gives you the same ratio without changing to 9 speed except that you will lose the a high gear ratio. Or if you are using MTB cogs like 11T to 32T (usual for MTB 8 speed) , changing it to 12T to 34T will also gives you a one step advantageous low gear but loose a high gear. There are also 11T to 34T cogs but hard to find and this will make you loose a ration in between the highs and lows.

Too bad you are using a 16 inch foldie, else if you are riding a 20 inch, . A foldie with XTR components, wahlao eh! I don't know which bike you are using but I am sure if you install the XTR long cage rear derailleur, the cage will hit the ground. Other than that most components can be used. The cranks though will be a wee too small. So, the shifter can be used but it will be a waste if you have an XTR shifter but other components are different. I also have to know what bike you are using as some folding bikes have 34.9 mm seat tube which can accommodate a front derailleur (largest non braze on FD) and many like Dahons have 40.9mm which will require you to get an adapter which acts as the braze on bracket for the FD.

You can install a 20 speed or a 18 speed groupset onto your foldie. First you have to check the hub if the frewheel is the newer or the old type. The newer ones will acommodate a 10 speed but can only accept 9 speed for the older versions but then again for a 16 inch wheel, 18 speed is more, more than enough for any elevation! The only components needed are the compatible shifter (left and right) , RD, FD with braze on adapter , cassette, compatible chain, crank (preferably 55T/39T) but a normal 53T/39 will do fine. Also the cabling housing and cables. For a folding bike a Sora 9 speed is good enough, couple it with a MTB cassette, it's more than enough. If you have more budget, you can opt for a Tiagra groupset. I think it will be an overkill to use anything higher than that but there are mini velos running on Shimano 105s. The cheapest components that is acceptable is Microshift.

To get a clearer picture, I will post photos of my bike later.

P/S also you have to get a wider bottom bracket, at least 118mm and also compatible to the crank choosen.

Wah! sudah rugi liao. The other day Rodalink's sale. Front is RM212 and back is RM416. Total less 20 percent is RM502 but both shodded with Schwalbe Big Apple. If you sell the tires for RM120, that's RM382 only for the pair of rims. But you can still get them at all Rodalinks outlet for RM628.

If the cranking feels soft to you, it means that you need really big cranks, like 60T or 58T. It can be found but I am not sure how to get them. Either that or get a larger wheel folding bike. The smaller the wheel, the easier it is to crank but at the expense of distance covered.

I think he is looking for the rims and not selling!

It is the same design as Dahon Formula S18 which is sold in American market.
