Any guesses on the weights of the aluminum altitudes?

Any educated guesses on the weights of the 730 and 750? I'm definitely no weight weenie but I hope they don't get too north of thirty pounds.

I wouldn't be surprised if the alloy frame weighed as much as a pound over the 790 carbon frame. The build kit on the 750 is maybe a a half pound over the kit on the 770MSL.

Hoping the 730 isn't too much of a porker. That bike is still one of my finalists. I'm it jing to order a new bike soon.

The alu Element 29er frame is 900 gram more than the carbon one. So if you can apply that to the Altitude frames, the frame alone will weigh 2 pounds more.

I want someone to pull two rear swingarms apart, and weigh the difference between the carbon and aluminum ones!

[rockyuphill]

On the 2010 Altitude 90's, the alloy seat stay was actually 100gms lighter than the carbon version.

[rideit]

That makes sense, actually.

Rocky told me this for these 2 carbon versions so guesstimate accordingly.

790 MSL 12.25kg/27.25lbs

770MSL 13kg/28.75lbs

The aluminium Instinct 970 is right around 29.8 pounds without pedals and that's going to be pretty close to the alloy Altitudes once you have slightly lighter wheels/tires and slightly heavier fork

I found this 2013 Rocky Mountain Altitude MSL 25 lb 14 oz (11737 g). Link 2013 Rocky Mountain Altitude MSL - kperras's Bike Check - Vital MTB

Email conversation with RM:

Me: I've read that the weight of the new 2013 Altitude carbon frame comes in at 2322 g. Can you tell me the weight of the aluminum version (size L with shock)?

RM: Since we do not have a frame only option in the aluminum I do not have a production weight. My educated guess is 2750-3000g.

The 750 that Bike magazine had for their annual Bible of Bike Tests is listed at 30.2 lbs.

I hardly believe the Alu Altitude will be lighter than the Alu Element frame, which I weighed and came in at 2922gram.

The Altitude chainstays will be shorter than the Element 29 so the rear triangle will be a squoosh smaller, so maybe 50-100gms lighter for the rear triangle wouldn't be out of line, the overall weight is likely to be about the same with the Ride9 bits and a slightly heavier shock.

Rocky Mountain will offer the new Altitude in five sizes and five models starting in early spring. Claimed frame weight for the full carbon version is approximately 2,300g (5.07lb) 2013 Rocky Mountain Altitude Trail Bike To Launch With 27.5" Wheels - BikeRadar
