I have the core 3 and it has the same wheelset. The M1900 does have a 370 hub. I have since upgraded mine with the DT Swiss ratchet conversion which basically turns it into a 350. I already had the 54 tooth ratchet so I was able to make it high engagement. The conversion kit is great if you are looking for more enga

Thanks for the info. So its a 3 pawl?
 
Ohlins upgrade
172psi is about 30% sag@~185lbs. +6 ccw (starting from 0 full clockwise) lsc, +7 ccw (starting from 0 full clockwise) rebound, hsc in open (or 1 on knob)

Also, still loving the RUNT upgrade on my Comp. The two suspension changes have made the bike so much better
Ohlins upgrade ain’t in my future so I might try removal of Neg volume reducers…

I'm gonna head out for a ride this afternoon with a freshly serviced shock sans negative volume reducers. I haven't ridden the bike with the shock set up that way so I'll report back with my impressions. I'm also messing around with adding tokens to the Fox 34 Factory fork. After 2 riding seasons I have a new desire to try and dial it in better than how I've been riding it since the second week of ownership. I don't really want spend the money on the Ohlins shock and then lose the Thirstmaster water bottle. For that kind of cash I'd rather throw a 36 on the front.

The only other thing I struggle with are brakes. I've given the G2s a legitimate shot at this point. I'm going to try a 200mm rotor on the back at some point but Codes might be the answer...

OK so removing the two red volume reducers in the negative air chamber of the shock was a positive change. I bumped my air pressure up from 210psi to 215psi in anticipation of a little more squish off the top and that was a good call. 215psi had me right at 30% sag. The bike was plush off the top yet supportive in the mid stroke. That said, I can probably increase pressure a little more still as I used all the travel a few times on the ride. I didn‘t experience any harsh bottom outs but I kept an eye on the sag indicator ring throughout the ride to see what was going on. If adding more pressure makes the shock harsh again I may actually increase the size of the volume reducer in the positive side of the shock. Overall, for a mod that cost absolutely nothing this is definitely worth messing around with if you’re looking to get better small bump plushness but also need more mid-stroke support out of the DPS shock.
 
Just a new owner of a core4 here chiming in. I pulled the trigger when randomly browsing( I wanted to see more pics of this really nice looking izzo frame ! ) It was all over once I realized they had some in stock. I've Always liked the izzo lines since inception. Only real negatives were that fed ex kept sending the bike back to YT thinking it was an ebike. It took 3 tries(ie 3 tracking numbers) and 3.5 weeks before the bike landed. nothing compared to what others experienced here but it was a quick shock to think someone else got your new bike based on a fed ex tracking number showing it was delivered already. fuggg, no haha it was all good.
Quik review. first ride the suspension was on the stiff side so the bike didnt feel nice down, climbing was firm to be expected. I was underwhelmed to be honest. The 2nd ride sag was set to 25% & 30% for the rear. This gave a little more supple action and the grin went up a few notches. very good. I'm riding it everywhere i've ridden the bigger bikes in the quiver. I'll be able to compare the izzo to the Spur as I have both. addicted bike hobbyist here. quick takes are the izzo has a taller feeling stack and a shorter cockpit, seated and standing ride position- basically izzo feels shorter and taller and slightly less confident. Spur feels ligher lower and longer, initially i felt more comfortable on the spur. both bikes rip. I've ordered a 170mm dropper instead of the 150 postman. (Large w 150mm just doesnt work if you want seat clearance for hips, drops etc-32 inseam here and I am also 5'10) I put a different wheelset on, its a new stans arch with orange race face vault wheels & DHF/ Aggressor combo. so far so good, these are really nice wheels by the way.

Izzo- better value for $ (but feel needed a smaller stem, better tires, & longer dropper, I want to say the izzo feels more burly but that is hard to say and feel confident. they are very close... I think i should try remove a headset spacer for a lower bar.
vs.
Spur (gx) bought used, couldnt get new from dealer, sensus grips suck :), changed to 35mm stem from 40, carbon bars, just put the dt 1200 wheels from izzo on it :) stock dropper height is perfect,

I thought I would sell whichever one I didnt like, but so far I dont want to let the izzo go, it is really fun. I know I havent ridden it much(4x) but I can tell pretty quickly how a bike will work, the wife can also ride it as its a little smaller. win/win :)

I have a question ??? Has anyone run 140mm? would a wieldly fox 36 unbalance the ride perhaps. Reason I ask is I could upfork both the spur and Izzo 10mm by putting izzo's 130mm 34 onto spur, & put the spare 140mm 36 onto izzo. I will try eventually but wanted to ask for thoughts.

One more positive before signing out. The bike came with no lockout. I am pleased not having to deal with any issues or lock out shinanigens. And the bars are 780's! I'll change saddle to fabric scoop, and some brendog grips. Stem length was brought down from 60mm to 40mm thanks to an I9 deal on PB. BIke looks cool with some orange accents.
thanks for reading if you made it this far.
 
^^ great feedback. I've gotten a few rides on my Core 2. So far I'm pretty happy overall with everything. Coming from Giant Trance 27.5, the Izzo is an improvement on everything I hope it would be. I've gotten a few PRs, but it's not substantially faster, but the pedaling is more pleasant than the Trance. On the downhill, the Izzo fees like its taken the edge a bit on brake bumps. The key difference for me is the 29 wheels over the 27.5 wheels.

The Blaze came with a 140mm - 51mm offset Pike. I think mine handles great. Others in previous posts have modified their Fox 34s to 140mm.
 
I think it makes sense to go 140 if you are looking for a more aggro Izzo than the standard 130/130.
Curiousity is edging me to try and see if the 36 will throw the bike off too much. A 36 combined with 44 offset should still handle pretty sweet I would think. Keep the smaller 2.3 DHF / aggressor.
I've heard its best to only make one change at a time to best feel the difference.
cheers
 
Hey Guys,

I was reading the thread with interest as I am currently debating between Izzo Blaze or Core 3. Both are available in my sizes. My concern is whether 140 my fork up front on Blaze might spoil that light and agile Izzo feeling core 3 might have with 130 mm? Also the pike on blaze has 51 offset versus 44 on core 3. Perhaps I am over complicating it ! What do you guys reckon? Would pike ultimate be better than fox 34? Stiffer? Some reviews praise core models but are not that happy with blaze pointing out demanding ride? In my head it all could be tuned playing with fork and shock settings.

Really depends on the type of riding you'll ride with the bike. I ride gnarlier trails, with a lot of rocks and roots. Not much flow, and very few smooth trails with berms. So with that in mind I think the Blaze is a way better value if they have your size in stock. If not, then I'm not so sure they plan on restocking the blaze, it was more of a quick build based on the parts they could get at the time. The Blaze is slightly cheaper than the Core 3, and very similar in spec. The brakes, fork, shock, and tires being the difference. You get much better brakes on the Blaze and if you are riding aggressive terrain the beefier tires are a money saver because because you'll have to replace the forecasters for any serious rough terrain. I think the reviews mentioned the Blaze was demanding based on the 51mm offset, as I understand it this can make the bike a tiny bit twitchier. However there are a few guys running the Blaze in some amateur enduro events without a problem. I haven't ridden one so can't comment on it being an issue or not. If you ride a lot of smooth fast and flowing trails the Core 3 is likely the better option. Those forecasters get up to speed and roll very quick. Also if you're doing a lot of flat pedaling and flowing trails, you might not need the RSC brakes on the Blaze and the Core 3 G2R brakes will be fine. I doubt the simple 10mm difference in fork length will "spoil the light agile feel", seems like a lot of the owners of the original run of Izzo's are swapping to 140mm anyway. If you ran the bike in it's high setting with a 140mm fork, the geo is pretty similar to running the bike in low with the 130mm fork. For what its worth, I'm definitely upgrading my Izzo to 140mm over the winter, I could use the extra travel on my trails, just deciding on a new fork all together or an airshaft upgrade. Good luck.
 
This might help some folks better understand the “normal” Izzo’s vs the Blaze:


Short version, a lower offset fork is more stable and a higher offset fork will handle tight turns better. A shorter offset fork increases trail.
 
Thank you guys for your opinions. I had my mind set for Blaze as it’s much better value for money with the tyres, better brakes etc. My terrain is quite technical and steep, all natural trails, roots, rocks, slippery and wet most of the time. EWS was hosted here 3 years in a row. I raced enduro but like to be under biked and now do more adventure spins traversing in the mountains with plenty of climbing and decending and wanted a more agile and lighter bike than full blown enduro machine. Going with core I planned to change front tyre anyways for something gripper anyways. Going with blaze I might change rear to something faster rolling.
 
Anyone here ever ridden Orbea Occam?
Can you give any comparisons to Izzo ?
My local dealer just got done Occam’s in and I’m still waiting on the Izzo I have on order.
Just curious what you think between the two.
Have not demoed an Occam, but did a little research. The general gist of the Occam is for a mid travel bike, it leans on the firmer side of things? Great pedaler, lots of anti-squat, great on flow trails, but definitely not the best in its travel for chunky terrain.
