Lightening the rear end...

[SKETCHY D]

I'm looking at saving some weight on the back end of my bike, first thing was getting rid of cog stack and deraileur.. next is finding the lightest rim hub combo, but still having something strong for freeride and dirt jumping. Any one know of a good rim, hub on the market..

Hope pro II is awsome. Get an alluminum axle. Splined spoke nipples. Syncros BH-T tires are insane light, sticky rubber, DH casing, and fast rolling. Tubeless, but run lots of pressure with the BH-T. I suggest welded single track rim or mavic 823.

Or try a 721, just don't be too hack or run too low tire pressures...

[coverider18]

i have a mavic 721 on my rear, its super light and still strong

[Dantes Inferno]

I think the 823 is lighter and tubeless ready. I also run 721s.

[Hack On Wheels]

I'm pretty sure that the 721s are lighter, I'll check the mavic site...

Ok, so 721 = 590g and 823 = 657g

[Dantes Inferno]

cool. How much does a rim strip weigh?

[Hack On Wheels]

Hmm, not sure.

[Dantes Inferno]

For me the tubeless rim strip would have to be 67 grams or lighter to justify a721.

I only run a 721 cus I got a killer deal.

that Stan's Flow ZTR rim is 470g, and you don't need a rimstrip, just tape. it's 28mm wide, they have super low sidewalls, to seal tires better, I want to try them..

Me too... except I would be afraid of destroying them... anyone sell them locally? Anybody sell Stans No Tubes kits locally?

[Dantes Inferno]

AKA had a few things of stans sealant.

Rims strips too? I might mess around with tubeless at some point to see what it is all about, should be fun.

823's also require those little nipple adapters... dont know their proper name... but you have to add those into the total weight of the rim. I think they are something like 100grams a wheel, plus it makes building the wheel a beeatch.

I love my ex721, both sets of them.

Maxxis makes a tubeless rim strip, similar to the Stan's, but lighter and alot cheaper. I've just never seen them in Canada. Maybe a shop rat can check to see if they can bring them in from the Maxxis distributor.

Good info, 823s now off the list.

I've mentioned this before on another post, but here it is again. I shaved 3 lbs off my bike by simply switching to 819 wheels, alloy nipples, Hadley hubs, and running full tubeless (Michelin 2.5s). I was running EX325 wheels with stock Formula hubs and tubes before.

819s with Michelin 2.5s? So is this for a DH bike or a do everything bike? 819s are fairly narrow, the extra width of the 721s is worth it for full blown DH, in my opinion.

The 819s were sort of a compromise between full blown DH/FR wheels and lighter trail ripping. They seem strong enough, though... I haven't had any problems bombing down the Shore. I recently dented my rear riding urban, but its effects have been inconsequential so far. I might throw on my EX325s and tubes for Whistler, though.

Sounds good, how long have you been running them? I'm assuming the tire profile is okay?

I've been using the 819s heavily since X-mas '06. Haven't had to lay a finger on the wheel or tire yet, aside from the occasional pressure adjustment. I believe they are Michelin 24 something or others. 2.5" wide tires.
