if u have queries about DH/FR or about biking in general... lay it down here...

Normal questions.

Does using 2.1,2.3 tubes on 2.5,2.7 tires will cause problems?

What kind of tire pressures for wet condtion, dry condition, mild condition?

Through my experience- it's OKAY. but bear in mind that the extra layer around the valve section is less elastic, thus, doesn't inflate all the way like the rest of the tube, so 2.1 in 2.7 is strongly discouraged. What is okay for long term use are: 2.1 tubes in 2.3 tires, 2.3 tubes in 2.5 tires, and 2.5 tubes in 2.7 up tires.
But that said, it's obviously still best to fit tubes that fit snugly into your tires.
Also avoid going the other way round and fitting bigger tubes into smaller tires. Now that, wouldn't work almost at all.

i use 1.9 xc tubes paired with 2.5 tires

really? i use 1.5 xc tubes in 2.35 tires.. works really fine (maybe i ride like an infant)

i use the Intense superlight 1.9xc version.

hahaha... so far so good! only flats if there is not enough pressure.

what are the drawbacks of putting triple crown fork (i.e 888) to light freeride frame (i.e norco 6 3)?
crack? bend?
any experience?
thank you~

hmm... where do we start?

biggest concern is the stress in the headtube intersection. thats where its going to go POP.

experience no, but each bike is designed with a recommended fork axle-crown length. too long (or too short) will result in geometry alter - 'non-friendly' weight distribution, poor handling and others. not to mention some headtube is designed for a singe crown fork (its not strong enough to take stress from lower and upper crown)

well im not the perfect guy to talk bout tech, but im a hardcore single crown fan that's why i replied

but its all up to you la how you want your bike to look like

thank you for the reply guys!

here's my sharing conclusion after swaping my 66 to 888 and couple of rides..
(from my point of view, my riding style and my little experience in downhill)

1) when im taking jumps, it feels like my front tyre are slightly heavier.. comparing from single crown weight distribution mybe?

2)my tendency of my foot leaving pedal is higher while airborne <-- mybe this is bcoz of my lack in skill.. LOL

3) my handling become worse..

thinking of changing it back to single crown... but i wont be back until 27th and JB is coming!!

owh, the front is heavier because of the fork weight itself, weight distribution is more of your body weight.

and you do feel handling and riding is more sluggish on 888 compared to 66.. not to mention sprinting.
one more thing, your cornering must be worse right? hehehe

set your bike right guys! dont go for the looks.

or maybe... just maybe i can set at 7 inches of travel.. maybe then it won't screw my geo and go crazy~

see how it goes first.. then considering change frame or swap to SC back.. thanks~

problem solve.. change new frame..
heavy but bomb proof.. i like

which frame?

lol.. just some old school frame
enough to make me smile during last jb race
