pix spam (long time no spam)

according to the star today newspaper....max 20 inch can go on board..

There's no saying that only 20 inch foldies are allowed. as long as it's foldable and covered or adhered to the schedule on this piucture, it should be OK. Komuters here from Kamunting/Taiping allows even full normal bikes. RM2 per bike.



See here, no problem for normal bikes as well.

i m talkin about lrt uncle not the komuter...

Lrt yes 🙃
1. Need to be ina bag
2. Off-peak hours only 10am -4pm then 8pm onward...... My gosh still cant take lrt then cycle to work


Nvm forget it....

Sifus,

Need advice on rear derailleur change.
My current setup is altus 8 speed, can I upgrade the following without altering others.

1) Change to Acera 8 speed
2) Upgrade to Alivio 9 speed derailleur, but still using 8 speed set up.

Can I get away without changing other things like shifters, chain and sprockets?..as I only want to get rid of the rather noisy and flimsy altus.

I'm riding a 2015 vitesse 8 speed.

Thx in advance

Yes you can use those RDs that you mention with the same shifter you have. The RD works on the shifting of the cage from nearer to further away from the hub. Therefore, you have the 2 limiting screws (don't mistake it with the lone other screw. The limiting screws are side by side) You just need to set the outer and inner limit the RD needs to travel.

Thx etigge. I'm aware of the functions of the limit screws, as I did set them on my foldie and my mtb. My current model is the altus rd310..with big jockey wheel..is that a long cage model?..So naturally I should be using back a long cage model, right?

Apart from the two options...can I use the 10 speed models like the deore series? Am I pushing my luck?

You can use the 10 speed RDs, no problem but it also depends on your wheel size , is it 406 or 451? 451 can handle up to 34 teeth at the rear and 406 can only take up to 32 teeth before the cage hits the ground. In other words, what cassette combinations are you using. 8 speed means the rear is 32 tooth maximum, so I guess it's OK. Some 10 speed SRAM RDs on the other hand have shorter cages. I would rather advise you to use the roadbike RDs like Sora, Tiagra and 105. Incidently the latter 2 types now comes in longer cages as roadbikes now also have upgraded to 32 teeths cassette. Get the Tiagra or 105. The oldr model 105 are now the same price as the newer Tiagras. But they are good already. Also get new ones as used ones , the spring tension of the RDs are not as sharp anymore, they shift well but not very instant.

Etigge, mine is 406 std dahon wheeler. Chainring 52T, sprocket 11-32T. Road derailleurs...hmm..thought of that but due to the 32T, thus I did not explore those...but will the altus shifter works with the road derailleurs?

Etigge,
Out of curiosity, why the road derailleurs instead of mtb derailleurs..better performance for foldies?

MTB derailleurs are meant for hard knocks and usually in long cages to accommodate 34, 36 and now 40 and 42 teeth. Road derailleurs shifts more smoothly and since your folding bike is more to road rides, why go for MTBs. Shorter cages (yours a medium cage can be used already) allows more precise shifting. I think the Altus shifters can be used with the roadie derailleurs. For road RDs ,Claris is Shimano's 8 speed offering, Sora is 9 speed, Tiagras are now 10 speed and 105 and above are all 11 speed now.

I also like to stress something though, there was an article about priorities when buying with a budget. Most of us cyclist in Malaysia got it the other way round. Supposing we want better shifting, most will retain their shifters but get better RDs. In actual it is the other way round. For eg. They advise you to get Shimano XTR shifters and you can use SLX or XT RDs. This is because the shifting is determined by the shifters and this determine the pull and release of the length of the cable which determines the accuracy of the shifting. Here , I observed, many use Deore shifters but XT RDs. Or SLX shifters with XTR RDs.

In other words, shifters are more important than RDs in shifting accuracy.

PS/ I have mini velos running Ultegra and another Tiagra and also 2 mountain bikes running on full Shimano XTs. Shifting on the roadbikes are way way better than the mountain bike's set. Even the Tiagras shift more accurately than the Shimano XTs. You don't even hear any click clacking when you change gear on road bike setups.

Im on the impression, or i read somewhere, due to the 32t cog...which is typically a mtb cogs...thus we must matched with a mtb derailleur, if not, the short cages from road derailluer can't shift to the larger cogs....guess my understanding is not correct.
It was also due to my bike comes with stock altus..which i thought is mtb set up.

Now that u enlightened me that road derailleur due come in longer cages...that certainly open up my options.

So, in short..i could make it work with my current 8 speed set up..by using a 10 speed tiagra / 105 medium cage, or 9 speed medium cage Sora or 8 speed claris.

Does all this derailleurs use the same hanger?

Roadies are going up nowadays. Shimano 105s and Ultegras now comes with 32 teeth options. Funnily not on the Dura Ace.

When I modded my wife's Dahon Boardwalk a few years ago, it was running on 9 speed. I put in a Tiagra 9 speed RD on it and it was a short caged unit. Tiagras were 9 speed then. You just need to check when the highest cog is engaged, is the top roller's cog is touching the cassette's cog. If it is, adjust the B screw or body screw (this is near the allen bolt where the RD is attached to the hanger). Adjust in so that the screw pushes the whole RD setup further away.

I don't know if this works, but in mountain bikes, they have this modifications where they modify the last cog to 42 teeth. Sometimes in the mod kit, they also includes a longer B screw in case the original one is too short. So, my guess is, it will work as well in roadbike setups. Just a small and longer screw you can buy at specilized nut and bolt shop. In fact change it to allen nut types and it will be easier to adjust than the original straight and philips head.
