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.
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

BBH with Minion DHf 2.5,
BB center-front axle
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.
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...
