With the EX8, the 2009 model are designed to accomodate 130 but for 2010 they went back to 120.

63-67k ata at lifecycles.

in my opinion, though, it could accomodate a longer travel fork than it was intended to(up to 20mm) without changing the handling so much since part of this extra travel (.7 inches) would still be used to take up sag, thus leaving you with less than half an inch of extra travel, slackening your tube angle by only 1-2degrees. . . not much in my opinion. mas precise(slower) pa steering, negating the need to change to wider bars. . . correct me if im wrong gurus.

Default Re: Maximum fork travel for Trek EX5

In my opinion, you can increase travel by up to 20mm - as long as you're ready to compensate with the slight change in handling. Kung di talaga puede mag increase travel then indi dapat gamitin mga U-turn and TALAS forks.

I also emailed Trek regarding increasing the travel of my fork from 100 to 120mm and got the same response as Leonard. I use the 120mm now but I just compensate with the sag. I run 30% sag so that when I'm on the bike the geometry is almost the same and I get a plusher ride. One of my Lbs mechanics said that the increased travel of my fork shouldn't be too much of a problem since I'm a heavy guy to begin with so the extra travel would be put to good use. I would presume that a 20mm increase wouldn't be too much of a change, but if you want to be really sure then maybe a 130mm fork or an adjustable travel fork would be best just to be on the safe side.

great point there sir acmi re travel adjustable forks. . . One thing remains constant though. . . It's gonna void your warranty, in case things go bad

Default Re: Maximum fork travel for Trek EX5

Thank you for the kind words - he he he. Warranty oriented talaga ang Amerikano. I don't like pushing my luck though so I wouldn't stray so far from the recommendations. I put my 120 fork side by side with a 100mm fork kase before installation and the overall difference looked very minute. Pag may sag na nga parang 100mm na siya. But if given a choice I wouldn't experiment too much. Mahirap na ma disgrasya.

Default Re: Maximum fork travel for Trek EX5

When they match a frame to a fork, or a shock for that matter, they also account for sag. 20mm isn't a big difference however it will change the way your bike will ride. For better or for worse? It depends. There are, frames designed for a wide variety of fork travels. IHMO, its better to increase travel rather than reduce travel recommended by manufacturers.

OT: I had a problem with my shock rp23, had a spare rp3. My shock is 7.5 x 2, the replacement is 7.75x2.25. You'd think 0.25 wouldn't affect the ride much. Yet it did. I had to adjust the fork (it was a TALAS) but I couldn't get that magic feeling, the bike felt wrong. Eventually I got the rp23 back and was never happier to return it to the frame.

If you like the way your bike rides, don't mess with it too much. You may end up with a lemon. =)

I agree on this one, since that .25 difference is actually more than an inch taking into consideration the leverage between the shock travel and the wheel travel, thus affecting the bike's handling characteristics

Default Re: TREK BIKE need to consult

well...you've bought it so we can't say pretty much anything about it. is it bnew? it's still sporting a 21 speed drivetrain with a compact crank. you pretty much paid for the Trek brand but not the components.

as for change....try to ride it first and know what works.

IMO, you might want to change your drivetrain to 9 or 10 speed later on. ride it for now then save up for the drivetrain upgrade. reason being is...it will be really difficult to find replacement for the drivetrain parts.

good shop by your mom. you should tag her along everytime! (works when you're own personal money can't cope with the wants)

my suggestion. upgrade when the parts become broken, decimated and unusuable. my 4 peso thought.

do not upgrade kasi you want it. that is the waste of all things.

use until it breaks. then upgrade. para maapreciate mo ang pagkabasag ng parts mo.

@iJeff17- Agree ako with anthrax76 on his question kung brandnew ba yan? Kung bnew, you may want to hold on to upgrades muna and save muna for future "needed" upgrades. Gaya nga ng sabi dito sa forum, laspagin mo muna ung bike and then ikaw mismo ang makakapagsabi kung ano ang gusto mong unang iupgrade.

Default Re: TREK BIKE need to consult

Sir iJeff - Yes, Trek is a good brand (I ahve my old school 4300 that still serves me well)
And as sir Anthrax said, for the price (and with the drive train), your mom pretty much paid for the brand.

Upgrades? Before anything else, get a helmet that fits you right and a water bottle for hydration. If you are a newbie (I'm guessing you are), no need to replace anything meantime. As long as it works and can bring you places, get out and ride! Ride the road to get acquainted with your baby... I had a 21 speed drive train for the longest time and just got to change it when it got busted (yes, 7 spd parts are very hard to come by nowadays). But these parts don't go out easy, it can take years of abuse before they break down.

I hope you can upload a picture so that we may have a look see...

Ride safe...

@anthrax76 yes sir it's brandnew when my mom bought it. So it means Trek is a good brand but the components is not that great? Hehe..

In the near future i will do that to change my drivetrain.

Thanks sir for your giving me an idea.

Do you happen to know Lance Armstrong? He rides Trek road bikes :) google him to find out.

I'm not saying the components are not great. what i'm saying is...the current trend in MTB drivetrains are already at 10 speed (11 speed is coming in real fast btw). your mtb is sporting a 7 speed drivetrain which is mostly found on mall bikes. they're kinda dated already. heck it's already difficult to find 8 speed components now. 9 speed is also getting harder to find.
