Amazing "Enduro"/ Gravity focused but not DH bike

Rating: Featured Member Review
The Good:

- Devours just about anything when pointed downhill
- Pedals stupid well for 162mm rear + 29er wheels
- Never felt any bottom outs even though the X2 oring said it definitely did. - Don't feel "on top" of the bike like a lot of other 29ers

The Bad:

- Climbing performance on technical climbs hampered by the head angle
- Slow speed switch backs take more tire sliding and body english
- Stock disc spec is too small in diameter for this style of bike

Overall Review:

This is only after a few days on a demo, also the bike I rode had Cushcore installed on the rear, but didn't ride a lower pressure than normal (low 20's).

Rides included:

  • Grubstake Loop inApex Park
  • Lift riding at Trestle Bike Park
  • Morrison Slide loop in Red Rocks

    I weight 160 and 5'11" tall, I rode a large. It felt like the perfect size.

First off this is the first 29er I've gotten on and loved. Having the carbon wheels on it takes away the acceleration lag from super low speeds that is just a part of having larger wheels. I'd be interested to see if having aluminum rims would really change my perception of the bike but having the CushCore insert in there probably brought it a little closer to alum. rim weight.

I've done a lot of bike demos the last month and a half (5) and it's interesting to me how some bikes have upper speed limits (Stumpjumper 29) and some bikes have a lower speed limit before they feel good (Bronson, and full on DH like my Intense M9). On both the Pivot 5.5 and Firebird 29 they felt amazing from creeping down sketchy low speed rocky technical lines to 30+ mph trails. If you find the upper end of the Firebird's speed limit you probably have the suspension set up wrong, or you're a WC racer. Another thing that blew me away is how playful the Firebird felt in comparison to the 5.5 (27.5" @140mm rear) and only a hair less than a Yeti SB5 (27.5" @127mm rear). This is super important to me as I'm definitely not a top speed guy, but if there is any little bump or trail cutting jump I'll take it and play on it. I was expecting this thing to just be a plow but it's SO much more than that. My favorite tech jib of nose tapping box jumps is a breeze on this thing, which scared me on the 29 Stumpy. 

I've long been a fan of DW link bikes and most short linkage parallel rotating suspension designs with air shocks (marin wolf ridge and quake). The mixture of small bump compliance + progression + climbing performance has always won me over. The Firebird 29 is no different. Lines that I had rode the weekend before on my M9 I didn't feel, much if anything at all, slower with 40mm less travel in the rear.

Things I'm not stoked on
The climbing performance on technical punchy stuff is definitely hampered by the head angle, you have to be really careful to put enough weight forward to stop the wheel from getting knocked around but not so much that you unweight your rear wheel. But if you're really worried about clearing low percentile tech climbs you're not looking at Enduro bikes... The wheelbase + HA also makes super tight switchbacks a bit more involved, but I don't know if it'd trade anything for that being better. More of just a spec quibble, but I think the front wheel deserves a 203mm rotor. Right now it really doesn't have the power to come into a corner super hot and slow way down. This IS a bike that is designed to win EWS having the extra leverage of a 29" wheel just makes it harder to stop fast with 180. 


If I didn't already own a dedicated downhill bike I'd really, really, really want one of these to compliment my 5.5. If you are somewhere where you value downhill performance and don't have super technical climbs you could definitely rock this as your only trail bike and hit bike parks no problem.
