Chiang Mai 2014

Don't ask me why but I always wanted to do the homeless grunge shot....
What's suppose to be a trip in Nov got delayed till now... better late than never. My annual pilgrimage to the mountains in Chiang Mai. Right now is probably the driest couple months of the year but nothing really prepared me from the diff of the cooler Nov-Dec period of previous trips...
By the way Apr-Sep would be rainy season
Being a little different this year with a bigger group... more tech and mech failures along the way was to be expected . I was nursing a badly setup fork on day 1 and started running into brake issues. Changed too many parts and gears before the trip... First time I'm using a dual crown here and popped an angleset in just before the trip. Day 1 handling is best described as a FUBAR ride. Thinking back... in the enthused state of riding here again, Dumbass Me totally forgotten to check suspension settings on the first day! SShhhhhhhh.......

Also.... Lesson learned. Stick with what works from before. Yes full length knee-shin guards be it they are on the dorky-robocop side of fashion appeal. Even if its not for the knocks & spills... the dry lashing vegetation on the shins during high speed runs makes a BDSM scene looks like a Disney fairy tale.

CW from top left: Yours truly f@#ked up rear brake. Broken spoke from Tinny's long should-be-trashed wheels
Someone's broke a chain, Ivan's clean snapped rail bolts. Plus my new abstract mountain leg-art. Thankfully I took all the brunt.. fork and bike escaped unscathed.
Reflecting on all the boo boo of the previous day...
and hoping that everything was sorted out before reaching the summit


Gotta love the classical "WTF-happened" look on Ivan's face when the moment of truth dawned on him that he either has to go the next 1500ft  all trial-sy without  post+seat or start nurturing a close proctological relationship with his seatpost going down those 45 degree rutted rocky lines.

Ok Note, our guide to the rescue-- gave Ivan his seat post and gone sans seat and post. Can still jump and whip on the way down! Some Madmonkey indeed!
Note and Ivan: And we can all see the budding relationship in those few days
All thanks to 2 cleaned sheared off bolts ;)

I always bring spare rear dee and hanger but never occurred in the past to bring spare brake levers... maybe it was something in my subconscious says.. and luckily I did...

Thankfully by Day 2.  I was back in my element. Suspension adjusted and got used to the new riding positions as dictated by all the changes on the bike... I have been going back to Chiang Mai yearly and each time my fork got a little bigger or beefier... this year was the ultimate.. cramping the RV-1 DH fork on a non DH fork and working all sorts of magic to make things workable...I totally understand why people do stick with these big forks when the going gets ..well Big. It is truly worth it and judging from the performance I see -- frankly I will stick with RV-1.. Nah no FoX or Rochshox for me still.

Spare XT lever.. Whew!

Uplift: The most understated but critical piece of equipment from our guide. Without which there will be no gungho posing ride shots if we have to drag bollocks pushing the bikes up each time in this dusty heat.

Ok -- let's get to some riding pics Plucked from various cameras... in no particular sequence to the days we were there

Go Pro Good arh!

"Mai Tu Liao...chiong arh"

Group shots.. .can there ever be a trip without one?

No CM trip, repeat, NONE is ever complete without a cuppa 3000ft up in the cool mountain air.
One of our guide has to take up babysitting role while ma hand grind aged beans and prep the brew for us
city-bumpkin-tourist-bikers that keeps coming back yearly for the novelty. But seriously... its really good good kaffee.
"Camera Front!" Quick lah.. Pose Pose Pose.. Hip sway, Eyes front, Heels down. Look the part damnit!


Our mystery rider-- Look Ma, no hands! This has got to be another "WTF-Happened" moment....and the entire sequence? Here
Virgin-no-more-Smurf-Merv: Ok he deserve his own shot with the peak after surviving not only the rides but all the sh!t we were trying to scare him with :) Should have a calloused perineum that he can wear like some paratrooper's wing back home now.  Chilcotin ho arh!

Doi Inthanon: Not particularly exciting on the way I must say and we travelled 80+km to get there... But hey at least its bragging rights back home that we been to the highest mountain in Thailand that's part of the Himalayan range eh!

ahhh.. this trip's most verbally abused rider want his portrait shot with the peak too. Yea rite... over all our salt laden hairy ass... Permission not granted Tinny!



Ernie-the-Detonator did it again... another dust bomb from him.... All lovingly captured for posterity by cam-whore Dave.





Seeing fk-all : Just gotta have faith in the guy in front of you not to fall...






The dusty aftermath of Doi Inthanon... actually back in the rest
of the usual trails twas' pretty much the same in this dry season



whenever there are streams and falls in my ride-- old habits die hard.
Hot Hot Hot: Me icy skullcap creation to make sure I don't have to haul
some heat-collapsed bag of old bones I've known since the Jurassic Age
(1) Ernie- "wait wait wait, don't take yet... I'm not ready" (3)No one beats Sit-Down-Dave. Camera or not, his ischial callosite stays glued to the seat- all day,all trails ;) (2) & (4) Kim and Les definitely saw the camera ... all that body English.... PoSeR TiMe! (5) And we were still wondering if Tinny was trying to do a TT aero position when the shot caught him.  (6) Ivan's damping-less fork for the day.


Mid Trail Arm Pump Relieving Break: Excited Merv relating dunno what
experience he has up there. Note and Andrew lending big sympathetic ears :)

Videos to follow-- Too many cameras, too much to edit now...


Riding is just a part of CM trips. Food glorious food, gorge till you drop, great local stuff to things we will pay a king's ransom to feast on back home....

From nice chic restaurant to donnowachacallit-point-your-finger-and-order goodies...


Of course there's the default touristy thing to do... More pachyderm art in the house now...



and city-Indiana Jones certainly needs a moped to get around as always...

2nd trip for the missus to CM. Looks like they are enforcing
the helmet rule more in the last year since we were there.
Were told it's a 500 Baht fine if the coppers decide to stop you...

Ok one parting ass-shot oops I mean group shot. Yup, just about everyone got their personalized Madmonkey jersey.



Conclusion: Think I'll be back end of the year again if no other big trip materialize in between. A new DH bike? Nah... the EG is really versatile and good enuf for me... Just gonna keep all my different forks and shocks to Plug 'n' Play as necessary. With  no WC DH courses around the region nor me having the guts to pile some 30ft air anyway.. a full on DH would be just overkill.

But rough "FR"ish terrains for some of the trails here sure can use a DH pogostick if the frame can fit. For which the EG certainly is up to the task with the RV1 plonked on it. In retrospect, back then I wasn't really thinking so much about pure DH rigs but veered in the direction of things like the TR250 or Morewood Kalula. Bikes that are comfortable and catered to switch around with a big single or dual crown....

There's no wrong or right but often with all the marketing hypes we all tend to fall into the "more is better" trap. Been there done that too... not that I have always been all that wise on things mtb. But with a much better sense of knowing one's own capability and terrains to match, its a lot easier to settle on what's really necessary and functional.

The single biggest change wasn't so much as having the bigger fork in there this year.. It was the head angle change with the Workscomponent set. Never thought it would be so radical but it did necessitate quite a fair bit of changes in my riding positions to accommodate the differences from before. A lot more forward but which was still a lot more stable It also meant having to watch out for front hoop washouts and do the leg kickout routines more often into high speed turns..  a la MX style.

With increasing speed each year, I can see the limits of me XT brakes... time to swipe that plastic for a pair of Saints now... Definitely a proven piece of component as seen on the other guys' bikes on this trip.

Adjustable seatposts? Duh-- learned my lesson from past 2 trips. Much as I'm an advocate for one on any trail bike but for these kinda  riding and the possible cartwheeling spills, an adj post is like trying to carry a porcelain vase on a ride. No more, not for klutz me at least.

XFusion RV1 - Smoke Chrome and new proto shock

Production is catching up... yup the Smoke Chrome RV1s are now available....

Some shots of last night's arrival... Shweet Creamy Schmoked Shilver...







And yup.. .that mystery prototype shock pop up in the fork packaging too...
Apart from asking for a 8.5 x. 2.5 to be sent over to me for testing- I have absozerolutely no info at this point of time and can only infer certain things based on the outward differences to other non-piggy air shock. Expecting a much firmer damping-- a solution to all those mid stroke wallow or segmented "telescopic" feel plaguing many of the other options in the market now? But like most other air shock in the non piggy class.. If this feels anything like the Vector HLR @ 30% sag but with the dial to firm up control on the climb,then its the final ticket for me on EG-lite.  Will see after mounting this weekend...

Good beefy feel and  not too much of a ho in my book @ 315...

Side by side with a Monarch RT3 for a size comparison. Both are 8.5 x. 2.5
Go figure why and what this new shock would be good for... ;)


Alright .... the sphincter contracting suspense got to be really killing by now..... .. so to spare further agony....

Initial Thoughts: X Fusion RV1 -ing the EG



RV1 - dual crown
EG -  6" frame

Can already hear the crescendo of "Noooo" in the background.... Yup, generally it wouldn't be wise to push frames this way but it this wouldn't be the first dual crowned EG.

Have to say it's totally unnecessary, having absolutely no complain with the Vengeance Coil so far. But its just tempting to see how it feels like (and maybe just maybe... to "justify a FR/DH frame in the months to come ;).

Probably not very useful for most folks but let's see what can be be discovered from X Fusion latest offering anyway.


Before launching into what's done for those that might be entertaining similar thoughts...

.... Most of the features have been covered to death by the various usual bike sites- Pinkbike, BikeRadar, Bikerumor and Vitalmtb and more..

Spec weight on official website is  2767gm which probably does not include the carbon lower guards and the axle. Bikeradar stated the claim weight by XFusion was 2902gm.

Mine came in @ 2988gm all in, uncut steerer. Minus the guard, bolts and axle its still 2833gm.

155 gm diff!  Spec weight doesn't include steerer? ... well whatever, still pretty impressive grammage for a coil dual crown.

Clockwise from top left: All in weight, carbon guards and screws
Weight with guards and axle. axle weight.
Stealth matte black with what look like an anodized finish. To be honest I just wasn't sure cause Mg anodizing certainly isn't common with parts used in the mtb industry. With the guards removed that should appeal to the no-frill camp.. But having been bashed on their earlier years graphics (remember the eagle on the gen one Vengeance?) I have to say their graphics department has come a long way. As much as an anti-carbon person.. I'm keeping those guards on if only just for the design on it.



Before & After: First thing first... getting all those numbers down

The RV1 is internally adjustable to 180 but if there is one XF fork that ran counter to the trend of  their lineup axle-to-crown measurement- the RV1 seemed to be on the short side (all others in my experience-- Vengeance, Slant and Velvet had been longer). Well of course A-C in DH fork can be adjusted somewhat by moving the lower crown, it came in with factory installed setting of 205mm, just 5mm over the full travel length.
Double method measurement for better A-C accuracy.
Vengeance 565mm. RV1 ~571mm (mfr spec @ 569mm). Diff = 6mm
Line of sight + caliper method = 6.5mm difference
I did wished for one little thing on the Vengeance Coil 170mm, just a smite more in the A-C department, with a corresponding increase in the bb center to front axle while trying to make various arm and torso reach remain the say,  or at least can be adjusted to be. Everything looks just "perfect" at least on paper without having to change travel or move the lower crown for now.

Old measurements on the Veng:
Bar Height,
BBH with Minion DHf 2.5,
Crown-stem,
BB center-front axle
Have no way to really get the HTA and STA changes accurately beyond those crude apps on the phone... so gonna leave it at that for now. Certainly the front was raking out a little more during rides. The change is perceptible each time with each A-C increment from 36Talas - Veng Air - Veng Coil and now finally the RV1.

While there is always the second lighter EG for general trailing purposes but if there are things that can be pedaled on this tank wherever its taken to... I'll rather crank it out than to push, hence the tolerance and range of the few crucial measurements are rather tight for me as to how much I can slack it out


Can only measure so much before taking the bike out and actually ride it...

Yup, made it on all the dirty loose rocky switch back ups on pedal power..

Still have to test out the various dials and coordinate with the rear shock. All I can say now is the compression and rebound damping circuits are very different from any single crown fork I ever had.
To keep the front end from running out away from me.. rebound speed is a lot slower than norm...

Screwed up shoulder says no airtime for now but the speed drops taken is a lot more confidence inspiring on this fork.

Since it was still ok getting up-- just playing with the idea of slacking it out with an angleset another 1-2 deg so as not to slacken the STA and increase bar height...


Just for comparison


And the overall weight now? Its just a number.........

More to come later.

26 Oct
After today, I'm really contemplating an angleset on this setup, if only I can be sure to keep the RV1  the EG for a while... cos the climbing was really no different from the Vengeance Coil 170mm.. pretty much is pedal power all the way on the ups. Restrictive movement of dual crown takes a little getting used to but any would have been the same.

The one thing to keep the front and rear boinks in sync was to down my rear spring now to a 350lb instead of the usual 400 that has been on the bike for the last 3 years. Still the rear is tying hard to catch up to the front that simply butter out entire root stretches and on rock gardens. But I guess a poor man DH rig like this will have to live with a little less than optimal performance. Still trying to find a sweet spot in the rebound but have a feeling I'll have to dial in the rebound on different trails more often now...
