Sea Otter : Fox Racing Shox Upgrades

April 19, 2009

It looks like Fox Shox are revamping their line a little bit.  Originally brought to you by Cyclingnews.com

The FIT (Fox Isolated Technology) cartridge-style dampers previously introduced on the 36 and 40 platforms are now littered throughout the 32 range for 2010 from the racer-oriented F-Series all the way through the coil-sprung Vanilla.

By separating the damping oil from air, the new floating piston designs reduce the chance of oil cavitation – and the loss of damping performance that results – relative to the existing open-bath models while the reduced oil volume also helps shed 71g, too. Additional massages to F-Series chassis shave even more weight, now making the top-end cross-country forks truly competitive weight-wise at 1.43kg (3.15lb) for the lightest models.

Smaller diameter damper shafts afford lower-friction seals, too, while an expanding rubber bladder at the top of the cartridge accommodates internal volume changes without any extra o-rings, thus maintaining comparably low levels of friction as on the open bath models.

Another feature Fox brought us their “ProTune”  to compete with the several suspensiong tuning companies out there.  Some companies, like Push, even revalve the suspension to make it ride as you need.

Xtracycle Build : 10 Step Build Process

March 28, 2009

This has been a long time coming but a few snafu’s in the second week of riding the bike caused the Xtracycle to get “hung up” until I could have someone fabricate a metal bridge for me.  Without further excuses :

Step One
: Remove your rear wheel, derailleur, chain and brakes from the bike.  Put these to the side as you will need them shortly.

Step Two
:  Attach the carpet material to the Front Attachment Plate (FAP) and then gather these parts: French Nut (2), Spacer Washer (2) (if you have a 130mm rear end) 32mm bolts (2), FAP Bolt, FAP, washer and nut

Step Three : Thread 32mm bolts through Free Radical and into your French Nut and Spacer Washer (if needed.) Do not tighten as now you are going to sit the drops out of your bike in between Spacer Washer and French Nut.

Step Four :  Align and hold with left hand your Free Radical so it is sitting FAP above chainstay bridge (if you have a chainstay.)  I attached my FAP bolt through the tongue of the Free Radical, behind my chainstay bridge, through the FAP and finally into the washer bolt. Do not tighten should be only hand tight.

Step Five : Tighten FAP bolt securely. Making sure drop outs are pressed against French Bolt, tighten 32mm bolt, you may need an adjustable or cone wrench to hold the French Bolt into place.

Step Six : Reinstall Rear Wheel, I needed to purchase a larger rear rotor (203mm) as this is what the Xtracycle is set up with for more stopping power and heat displacement.

Step Seven :Reinstall Rear Derailleur and Brake with extra long cables and housing provided by Xtracycle.   I needed even more brake housing with this than Xtracycle provided as I run full length housing down my bike to my disc brake.

Step Eight : Add the chain links to your old chain, reinstall chain.  Please make sure to check the life of your chain/cassette before doing this.  If you they are worn it will cause the new segment of chain to slip. Click here if you need help adjusting your derailleur.

Step Nine : Check everything over, refer to Xtracycle and your owners manual for specific questions.

Step Ten : Go ride already!

Notes: Please grease all threads and bolts.  If there is interest of specific directions on parts please let me know.  This is a brief run down to show that building an Xtracycle is not as difficult or daunting if you have some bike mechanic skills!

Xtracycle Build Up : Parts Bag

March 28, 2009

Arleigh is building, documenting and writing out her build up of a Salsa Ala Carte mountain bike with 650b wheels and a Xtracycle Free Radical Kit.

One thing that is a bit daunting if you aren’t mechanically inclined is the huge parts bag that comes with the Xtracycle box.  There’s bit pieces and things that simply don’t make sense.  This requires reading directions and diagrams which, let’s be honest, most folks don’t.
First I seperated all the goodies into seperate piles to make sure I had everything I needed. There’s a couple stray chainring bolts that didn’t make it to their right pile but you get the idea.

Kickstand plate, and soft, durable fabric to save your frame from being scratched.

Chainring bolts used in with screws to attach the freeloader bags to the Xtracycle frame.  This is a new design to keep the bags from having to be tied to the frame.

Avid Rollamajig. Used to help ease the bend of the derailleur cable into the derailleur.  Mostly used if the cable stop is too close to derailleur, or for older style Shimano derailleurs. (I didn’t use mine.)

French Nut. These are the parts that your frame rear dropouts sit on.  They tighten through the drop out to bolts on the outside of the Xtracycle frame.

End Caps & Spacers. These seem to have many purposes (spacers, plugs, etc), I’m still researching all the possibilities for them.

V-Rack Spacers.  Used with the above to space out your top deck.

FAP Bolt.  Used to connect Xtracycle at the FAP tab near the chainstay/bottom bracket area.

4 Shorter Bolts.  Goes with chain ring bolts to attach Freeloaders.

Washers. Big washers are used to space out 130mm frame for Xtracycle.  Small washers are used with bolts.

I’m sure that there will be more parts along the way, and uses but we will document as we go.

Thanks for visiting

We are excited of the upcoming venture and what the next years will bring to the cycling industry!
