apart of the bit hard to find 26" what other disadvantages of the 2sixxer?

do u happen to know where can i rent MTB for a day? i just wanted to try again the MTB before i spend few k...

There is nothing really wrong with 26" Mtb just that it's really out of date. Rim and tires are hard to find. Due to the smaller wheel, it don't roll over rough terrain that well as bigger wheel bike. And it don't look cool at the trail anymore. LolBut then again, a lot of downhill bike still sports 26" wheel. But since you are getting a bike now, just go for the bigger wheel size. If you get a 26" MTB and love mtbiking, it won't be long before you decide you need to buy another more modern MTB.

Btw, you don't really get to know mtbiking on a single ride. MTBiking are categorize into 4 types ie XC, trail, all mountain, and downhill. Most people start from XC, but the fun is really in the downhill.

Don't expect too much from fork that comes with budget MTB below RM5k. A good fork is almost the price of a budget Mtb.

I converted my 2x Shimano SLX to 1x with a Kore 30T chainring. For the cassette, I put a Sunrace 10 speed 11/42. Spend less than RM300 for the conversion and I am really happy with it. Don't see the need for 11x speed so I keep my SLX shifter and dérailleur. The Sunrace cassette offer smooth ratio from 11t up to 42t.

Raceface chester copy?
Ok thanks for the advice. I think i'll buy the shock pump and play around with the setup.

It's just like the raceface Chester. My friend use the Chester in his nomad 3 and one thing different is the length of the spike pin. Chester's spike is really long and look scary. Will do a lot of damage to your skin if you slip and scratch your leg on it.

I have used mine for 6 months already and they are really good.

I am using the ori seasucker for almost 2 years now. It's the best bike mount to me. Hold the bike really firm and fits all types of car. I don't see how the seasucker can come of if properly attracted. Easy to mount on the car and removed in seconds. Real easy to service too.

Only disadvantage is the price. I will make my own if I need another as I have found the vacuum cup which is identical to those of seasucker. Just need to fabricate the plate and the truaxel mount.

This is the original seasucker that I use. It use 4 vacuum cup with one spare cup. The whole thing is actually very simple. It's got a base plate where 3 vacuum cups are screw on to it. Then the axle mount screw to the top. The rear tire vacuum cup is just attach a Velcro into the vacuum cup base.

So Just buy 4 of these vacuum cup. Make the base plate.

And attach a mount

Make sure you buy vacuum cup instead of suction cup. Vacuum cup have much higher holding power.

There are many ways you can mount the seasucker on your car. Below are just 1 eg.

I knew a fact that one of my friend lost his bike due to seasucker - on the highway (couldn't remember he overtook or that lorry overtake him), bike off the roof, ended up with another bus/lorry run over his bike.

Gone case. FUBAR.

Anyway, not to scare you, but it might happen.. and rubber has its wear and tear?

Still the best is in the car, with the car body aerodynamically protect the air resistance on to the bike.. compare to when it is out of your car.. especially on the freeway.. tak kisah if it is in the seasucker or any bike rack..
*
Is he using seasucker or other knockoff?

One very important thing when using seasucker is clean surface before mounting. I always bring a bottle of water to wash the surface clean and wet the rubber of the vacuum cup before mounting for proper seal. And also ensure the every cup is properly vacuum.

There are 3 vacuum cups on the front mount and I found it quite impossible for all the 3 cups to lose seal at once. I mount 2 of then vacuum cups on my front windscreen so I can see the cups while I am driving.

seasucker. yes, he told us the incident with the pictures of the damaged bikes yada yada.. and yes, sorry i don't have the pics to prove you anything..

true that you can have the visibility of the sucker suctions, but it will take you milliseconds for the sucker to pop out right? and a small force to lift the edge and let the air in?

nevertheless, just take extra careful on any of the bike carrier that you guys are using..
p/s: i am seriously considering selling my Thule Archway 3. Price wise +-1k (retail), going to let it go for RM350.  brows.gif  COD only, PM me if interested.

Don't get me wrong. It's not I don't believe you.

From what I see, the fail rate is very low. Sometimes it can be the fault if the user as they do not mount it properly eg dirty surface, not fully vacuum etc.

I just find it hard to believe that all the 4 vacuum cups can pop off at once. That possibility is almost zero unless you hit something. I tried before in my house where I mount the seasucker on file floor tiles. Try to remove it by pulling it off but that thing just won't go. A single vacuum cup can hold 200lbs. Even if one loose pressure, the other is still more than enough to hold the bike.

But you're right. There is still a slight possibility that it can go wrong. But after using it for 2 years, i have very good confidence in the seasucker.

Permanent roof rack will increase fuel consumption by at least 15%.

Get this. I have tried a few led and this one is really bright and price reasonable.

It has 4 pcs XM-L T6 LED which is very bright and evenly distributed. The power consumption is great as I have juice left after 2 hrs ride. The size is not too big too.

Solarstorm

Its not what I use is the best. I have tried a few types. Those chinese LED light with single led is just not bright enough. The may be good for riding on the road, or in the park, but if you want to go into trails at night, you really want something that is really bright.

I have wasted a lot of money on lights and in the end I find the Solarstorm solution as the one I would use. My friends use Rm500 Magicshine which is really awesome but I won't go that route.

But then again, bright is a relative term. To some its bright but to others it might not be bright enough. My night ride group are mostly using Cateye or Magicshine which are some of the most expensive led light and I know what bright is.

End of the day, this forum is about sharing and I am sharing my experiences.

This is the lighting I use for my night MTBiking.
I got a light mounted on the handlebar

And a Pouch for the battery pack just beside the light

The Battery Pack is DIY with 4 pieces of Panasonic NCR18650B Super Max 3.7V 3400mAh Rechargeable Li-ion.
Last night ride about 1 hrs 30 mins riding and still 3/3 bar left when I reach our parking are. Only then it drop to 2/3 bar
when I was chating with friends in the car park.

Another on the helmet using 18650 battery too.

This is how bright the handlebar light looks on the trail. Very good light distribution giving me about 10ft wide from 5-20ft out front of evenly bright light.

Hi, just started cycling about 2 weeks ago. Noob rider. Silent reader too. But experienced light builder.

About the light you all discussing. About those (I love diy light stuff)cree t6 smd(or u guys call it led) is rated 5v 5watt smd, depend on manufacturer, you can overdrive(overpower) it to 6/7watt(usually used for strobing) or some underdrive(underpower) to 4watt to reduce heat.

Their 10watt rate is around 400lm. Measured 10cm away from bare bulb (no reflector or lens).

What you see in the ground luminated from the light is not the measurement of the lumens. Depeending on the reflector/lens build for the t6, it affect how the light is concentrated or spread wide... Spread light always is softer than concentrated (those of you have zoomable Torchlight would understand) so lumens doesn't determine your illumination, reflector and lens plays a major factor too. That why branded like topeak, lynnze and cateye even at lower rated lumens seems brighter is due to the lens/reflector designs

The usb mini light someone posted few page back, the dual t6 is fired around 8watt(4 watt each) at 5v consuming 1.6A... yes, 5V 1.6A for several reasons, pumping 10watt will consume 2A from your power bank running for 15min will kill your powerbank circuit . If your power bank doesn't support 2A(or it's 1A PB) it might instantly turn off or work at lower wattage. I would say the is mini light fires about 700-800 actual lumens.

My personal advise, Get a good long life light that last min 3hrs, low power last 5hrs . Lumens is not really a big deal if you ride on well lit road, the light is for ppl to see you. And avoid dark roads at all times. You don't want to get robbed of your bike.
*
I agree with you, the lens is a major factor. It will make a big impact on how the light is distributed on the path. Some poorly design light have the light concentrated on a small spot. They can be very bright and can shoot out 100-200ft but this kind of light is useless for night MTBiking. A good light for MTBiking is one that is gives you evenly disperse light from 5-30ft in front of where you are going.

Road biking at night are different from riding MTB at completely dark trail. Road bike can get away with decent light as the road is not so dark and are flat and smooth. MTBiking at trails with technical downhill requires really good and bright light.
