2015 anthem sx 27.5 advanced RockShox Revelation fork travel

[alister]

Hi all, it's been a few years between posts but i'm back into it with a new lightweight bike after 4 years on a 2010 Reign sx (amazing bike). I'm finding the 120mm travel a bit restrictive and a bit aggressive in the geometry stakes.

I was wondering if my current forks are adjustable (via spacer or otherwise) to 140mm travel internally (the website states that the 27.5 version is only available in 150/140/130/100mm as per https://www.sram.com/rockshox/products/revelation-rl )

Although giants website says: RockShox Revelation RL w/ 15mm thru-axle, OverDrive steerer, 120mm travel

If not adjustable is there a viable replacement anyone can recommend?

Thanks in advance,
Cheers n beers
Al

does it have a sag marker for longer travel?

if so, the new RockShox forks forks are adjustable via replacement of the air spring rod. these are preset, so a new rod is required for any given travel. (apparently you can cut up to about 10mm off though)

Sounds like you should have got a Trance. Given the SX is already the longer-forked version of the Anthem platform, I'd be wary of putting anything longer in it for risk of compromising the headtube attachment.

Thanks guys, yes it has 2 x tiered sag markers (one gold, one hollow black) that appears to go below the top out point. The difference between the two 30% indicators is only 10mm though. I'm just wondering if this RL is a special OEM setup for giant due the 120 travel.

perhaps a similar setup internally to this? http://forums.mtbr.com/shocks-suspension/rockshox-revelation-rl-140mm-150mm-797952.html

I came across this bike second hand with only 500ks on it and cheaper than a new aluminium specced anthem sx, and with the spec I couldn't really pass it up. May swap out the frame if 100mm travel gets to be too rambunctious!

My bet is that it is a 100-120mm travel OEM fork, given that they spec Revelations on Anthems and SX's. But who knows. They use 140mm Revs on Trances too.

It's a 140mm Rev set to 120mm.

Have a read about this anthem with a 130mm pike on it.

Perhaps your issues could be fixed with an angleset?

Thanks all!

Great read Clint.. that sounds similar to the setup i want.

I've been digging around and the solution seems pretty simple for once! Rockshox Revelations, along with a bunch of the other solo air forks can be altered with the use of an air shaft replacement and changing the "bottomless tokens".

Video how to: https://www.youtube.com/watch?v=7WcCIFguChA

Service manuals and spare parts catalogs to find the right air shaft model no.: https://www.sram.com/service/rockshox/7,107

Bottomless token chart: http://fcdn.mtbr.com/attachments/sh...d1428690248-bottomless-tokens-2013-reba-1.jpg

I've ordered a 150mm air shaft from the US (ebay) $50 posted : part no 11.4018.022.000. And I only have to remove the 3 factory installed bottomless tokens.


Probably going to get spammed for this but i think the change in geometry (120mm to 150mm) should be equivalent to the head angle, bar height and bb height i want.
Will put up a build update once the parts in! Cheers all

It's worth stating that IF you suffer a frame breakage due to the fork travel (particularly due to its effect of slackening the head) exceeding the frame's spec you're unlikely to have warranty support.

FWIW on my Anthem I eventually extended the stock Reba100 to 120 and when the trails I rode even outgrew even that, it was time to get a new bike. Happily on a Trance SX now.

I was considering bigger forks and angleset for my anthem but I reconsidered. Going to go something along the lines of a Banshee Phantom or Kona Process 111 next instead. I don't think the anthem was designed with abuse in mind.

cheers,

Install an angleset

Mate of mine has the same bike and installed an angleset, made a noticeable difference.
Crane Creek angleset not a huge outlay for slacker front end.

Same here; after upping fork to 120 I was then considering angleset but I knew I was going to break the frame if I kept pushing it. It is a lightweight XC bike.
