So im thinking of building a more XCish bike and lightening my DH bike into a more DH/FR bike that can pedal ok.
as it sits now i have a canfield jedi that weighs 39.5 pounds and want to drop it to 38. shouldn't be too hard. im probably getting some race face atlas FR cranks to replace my holzfeller OCT's and switching tires should help too.

i figure the best place to start is my tires. i am currently running 2.5 intense 909 2 ply up front (1400 grams) and a Maxxis High roller 2.5 3c Rear (1300 grams)
I am running them tubeless with mavic 823's so any suggestions should be compatible with running them tubeless with this rim.

i really feel i don't need that heavy of tires. something in the 1000-1200 range would be ideal. plus something a little smaller in the back like a fat 2.35 or a 2.4

i am mainly looking at the specialized chunder sx 2.5's (do they mount up tubeless good?)
maybe some other specialized ones.

i don't really like 2.5 maxxis minions or the highrollers really either.


maybe some schwalbe's, geax, or something else???

so bring on the ideas

I would defiantly recommend Specialized chunder but in a 2.5 they seem to run on the big side. And with the sx 2.35 you get a Kevlar bead that seals up with stanz on 823's really nice.

so you said 2.5 in one and 2.35 in the other. which one?

maybe a 2.35 rear and 2.5 front.

i also saw a clutch that looked good. they look expensive though.

the chunder sx's do run on the big side. My 2.35 are really more like 2.5s, don't know whats up with their measurements. great tires though.

Bubba, I switched from 2.5 Minion (FR) front and 2.35 Minion (FR) rear both single ply to2.4 Big Bettys ghetto on 721 and they are fantastic. Single ply with side wall more between single and dual. Seem to roll well for the amount of grip they deliver. Fantastic in breaking department. I have been thinking about trying something to make a comparison but like you weight goes up almost imediately. I have looked at the intense range but they seem weighty. Kenda reviews seem mixed so looks like the BB are it for now. The 2.4 has alot of volume, feels cushy and handles low presures.

+2 on the Chunder SX's, i am running the 2.5 on the front and the 2.3 on the rear, its a great combo, its not 42a rubber, but it grips pretty darn well, and I am not replacing them every 2 weekends! They held up really well at snowshoe in the rocks tubeless. I am keeping a pair of the D2's pro's as a backup in case i cut one, but i always keep a pair of back up tires around.

Eric - I've been riding the single ply 2.5 909's on my crown for the past few weeks - tubeless on 823's. They set up super easy and weighed like 1020g. Plus, they're only $18 at jenson right now. Specialized tires are a rip-off unless you have a hook-up...

i have considered that as well. how is the single ply? is it pretty thick? i was thinking of trying that cause my friend has one i could just take from him. i know toni ran them for a while on his socom.
maybe ill keep the high roller in the rear and put a single ply 2.5 in the front.

have you tested it out good yet? like fast rocky stuff or big hucks??? i have learned i can't gauge stuff off how toni rides. he is too smooth of a rider and i am too much of a hack.

I've got one of the Geax DHEA 2.3 tires running tubeless on my rear ZTR-Flow. Traction is great. The 2.3 is about as wide as a 2.5 Maxxis. Tire came 10 or 20 grams under 1000. No flats running tubless. works great in the wet and dry.

I recommend. 5/5

I also have some of their 2.5 LoboMasLoco tires - their HUGE. too big really. better for mushy spring trails I find it a bit washy on hardpack. great tire sitll just not as versitle as the DHEA so it gets 4/5

Tubeless Big Betty's.....only 860g.
i know they are a great option but i think there is a point where you start to lose stability through rocks when you go really light.

i think 1000-1200 would be a good comprimise for wieght and stability. i might try the intense 909 single ply's. they seem pretty sturdy and for $18 each its not a big loss if they suck

If you opt for Schwalbe Big Betty's, I suggest you weigh them. Although the claimed weight is under 900 grams, my Gooey Gluey Big Betty weighed in a bit over 1000 grams.

I am running 2.35 Small Block 8's front and rear with stans tubeless and the strip on my Trek Session 88DH, they are super fast and on dry loose over hardpack are as good as anything I have tried. The rubber on the sidewall is kinda thin and I have a few cuts in the rear sidewall rubber from sliding in shale rock etc...but no leaks yet.

They measure right at 2.35 and are nice and round plus corner predictably. You can nip off the inner side knobs with an end or side cutter if you want to modify the grip and take even more weight off if you like to fiddle and get creative.

Did I mention they are super fast, I am hooked on these tires for riding when it dry or slightly moist. Total crap in the mud mind you, who cares they fly in everything else. I run 34psi front and 38psi rear but I am heavy at 230pds, your mileage will vary.

Mine weighed 740 grams each, I know its supposed to be an XC tire but I run mine DH all the time and love em...very versatile if the terrain is not covered in sharp rock where you need a heavy carcass to survive.

I just bought 2 of the 2.35 Intense 909 EXDC dual ply tires from jenson and couldn't be happier with their grip, weight and durability thus far. Both my tires weighed right around 1100g and that is for a tire with the same footprint size as my 2.5 1250-1300g maxxis minnion DHF's. Admittedly the Minnion has a slightly larger volume, but thus far I have no complaints about the 909...though I may try to get my hands on some 2.5.
