So... I got my 2010 Q620 a while ago... Creeping up on a year now, I guess. I rode it in complete stock form (minus the swap of SPD pedals) since its purchase date. As with any avid rider, the bug to upgrade nailed me hard!

So I went to the LBS (I'm a loyal, local buyer most of the time) and we put together a list of stuff! Some of it has been purchased elsewhere, but most (and the labor) was done locally.

So far we've done:

Mavic Crosstrail wheelset (setup tubeless)
Devox TAR 2.1 120tpi
Shimano SLX Front Derailleur
Shimano SLX Rear Derailleur
Shimano SLX Shifters
SRAM PG980 Cassette
SDG Fly I-Beam saddle and post.
Alligator Wind-Cutter Ti-Ni Rotors

Good stuff. Before the various parts were installed, the bike was around 35 pounds. ...yes, heavy. I had the thick slime tubes because I was destroying regular tubes. After the swap out, the bike is right at 28 pounds. The shifting is amazingly smooth by comparison to the Alivio/Deore parts I had.

I still have plans to get a new crankset and BB (I imagine I'll shave some more weight there, and get an even smoother "ride", in the context of drivetrain). I also am searching for a new fork. Some of the ones I'm looking at are around 2 pounds (or more) lighter than my stock fork. I'd love to have my bike in the 25 pound range.

Finally, I think I'm going to swap my front tire out for a WierWolf... I get a bit more front tire slide than I'd care to have (after swapping to the 120tpi tires).

...it's awesome, and it sucks, because I don't want to be poor, but I love putting new bits on my rig. :D Does anyone have any positive opinions on the WeirWolfs?

An update:

I have since upgraded my fork to a RockShox Tora 302 Trail (Solo Air). Good stuff. Hopefully I'll get to hit it some this weekend. I have to get a shock pump first though. :D

Heh, I'm having the same dilemma. I have a handful of brakes that I'm tossing around.

I'll post up when I eventually choose one.

I have the same Q620... I am newer to biking and can say I nearly fell outta my chair when you said you went from 35 to 28 lbs... holy moly.

Although I thought stock weight was around 31.5 lbs ( i will have to weigh mine when I get it back from the bike shop).

time to start pricing upgrades

Well you're actually correct. Stock weight was claimed (by Felt) at 31.5 pounds. I think (as with all manufacturers) that that might be a little optimistic. Call it 32 pounds. Mine was so heavy because I put the super thick Slime tubes in it. While at my LBS, we weighed them, and each tube was something stupid like almost 2 pounds.

From its heaviest (~35 pounds) to it's lightest (now sub 28 pounds) is how I outlined it. :)

Here is my bike, as it stands now:

Frame: Felt Q620 17.5" 26'er
Fork: RockShox Tora 302 Trail Solo Air
Wheels: Mavic Crosstrail
Tire (F): WTB WeirWolf 2.3 UST 2011
Tire ( R): WTB WeirWolf 2.1 UST (Uh… older)
Crankset: Shimano FC-M361-L (Stock)
Cassette: SRAM PG-980
Chain: SRAM PC-971
Rear Der: Shimano SLX Shadow
Front Der: Shimano SLX
Shifters: Shimano SLX
Brakes: Tektro Auriga Comp (Stock)
Rotors: Alligator Wind Cutter Ti-Ni (180f/160r)
Handlebar: Race Face Ride XC
Stem: Bontrager RaceLight 100mm
Grips: SRAM White Lock-On
Seatpost: SDG I-Beam Aluminum
Saddle: SDG I-Fly
Pedals: Shimano SPD (Don't recall exact model)

At last weigh (5/22/11), 27.7 lbs

I figure I might be able to shave another pound (max) from a brakeset and crankset/bb. :) I obviously didn't go with the most expensive and lightest parts available. Whenever I start building my dually, I'll end up getting some sort of SID or Reba fork for the bike, and I'm sure that will shave even more. In my personal opinion, I think ~25 pounds is what I can hope for out of this bike, without being one of those insane gram counting weight weenies. :D

Here is a picture, you can kind of see it behind my wife's Q520. :)

I see about the weight issue... All good.

So if I can ask how much you have invested in upgrades?

Going tubeless was a massive weight saver over the Slime tubes.

...as for cost... I jumped in another thread about sub $2000 hardtails, and mentioned there that my bike was just barely under the $1900 dollar mark including the cost of the original bike.

So figure around $1250 for all the upgrades. :)

I did a few of the installations myself, some of it I had done at my LBS. :) I'm sure you could get the parts for "cheaper" and do the work yourself, but I like to be as loyal as possible to my LBS. :) It ends up not being "cheaper" when/if you have a problem that you can't fix (if you cut the LBS out). The guys at my LBS are often very helpful (both with knowledge and cost), especially since I bought the original bike and much of the parts/labor there. :)

If I had to guess, you could probably get similar parts for the 900-1000 range altogether, but you'd have to do all the work yourself, and you would be on your own for any issues that might jump up. :)

Not particularly detailed, but here's a nifty image of my rig. :D

Damn, it looks amazing. Let me know how the tubeless tires are, I've been thinking about upgrading to them if I end up going with the 620 which if all goes well I will.

I am working on mine 2008 Q620, but I am alsostarting to build a Santa Cruz Heckler FS Bike.

Here is what I ahve on the Q620 so far:
Stock Frame 19.5"
Reba Team 100mm Fork
LX Crankset
X.7 Shifters
x.7 derauillers
Formula Puro Brakes with Formula 160 rotors
Sram PG-980 Cassette
Stock Saddle--Bought a WTB Pure V today--it goes on tomorrow
Stock WTB SX24 wheels (these gotta go) Weirwolf 2.1's on both ends
Stock bars and stem
Sram 971 Chain
Worn out stock grips
Forte Platform Pedals

Other than the wheels, everything else is pretty good. Wheels don't do the rest of the bike justice.

I bought the bike used for $250. Probably have about a $1150 in it now. Stupid, but it was fun!

Man, the 620 is a phenomenal bike. I love mine to death. The geometry feels fantastic, the bike is solid... love! :D

I'm about to start (as soon as it gets here) a Jamis XAM 2.0 from up build from all the scrap parts I have lying around from the 620 take offs. :D

I just bought a 2006 Santa Cruz Heckler frame with a Marzocchi Z.1 Freeride FL 140mm fork with a Chris King headset. The Z.1 needs rebuilding, so I bought a Rockshox Pike with a 20mm through bolt axle and put it on the frame. I have a set of Formula RX brakes coming, and I liked the X.7 shifters and derauillers so well on the Q620 thal I bought another set for the Heckler. Still need wheels, handlebars, saddle (If the WTB Pure V that I bought yesterday for the Q620 works well, I will get another for the Heckler since it was on sale at Performance for $40), cables, and a crankset so it will be a while before the Heckler is ready to ride.
