Crank Brother's Cobalt SL Crank

Has anyone had any experience of the Cobalt sl crank or seen any test reviews on it? I'm running a Truvativ D5 with shimano diore lx shifters/derailer and an SRAM (not sure which one) 9-speed rear cassette and was wondering whether:
1. I will notice a difference in performance/feel of my pedalling/gear shifting?
2. I will benefit from much weight reduction? (ie. not sure how heavy Truvativ D5 is versus the Crank Bros crank.)
Any comments/opinions on this crank would be much appreciated! It looks damn sexy either way...!

Oh... also forgot to mention i'm only an intermediate rider, only been riding an entry level 'proper' mtb bike for about 24 months now, a beautiful GT Avalanche 1.0 which seems to have a v good spec for its price (œ400), and again it looks hot which is a lot of my motivation for buying it, plus a tight ride obviously, i've hammered it a lot and it seems to take it all in its stride without too much changing since I bought it, still feels really solid but am just looking at ways to reduce weight and improve ride quality without having to buy a new bike basically! My only major disappointment with my GT at the mo is that it is only running on 8 out of the 9 rear gears, i've tried (and others) to get it to click into all but it always skips the last one before the highest gear, bloody annoying! Thinking an upgrade to shimano XT/XTR cassette and rear derailer might help to stop this?
Is all the above gonna be possible on a GT Avalanche without me having to buy other things like new bottom bracket etc?
cheers,

Waste of money for you I'm afraid. œ200 for a set of crank arms and rings (no bb) is insane for a GT Avalanche.
Buy a set of Shimano XTs for œ100 with a BB. You get external bearings (ultimately, better than ISIS) and a nice light and stiff crank.
I'd spend œ450 on a full XT groupset from Merlin. You will get cranks, mechs, brakes, wheels and all the other small parts. Much better value than buying parts seperately.

Thanks ddoogie, much appreciated! The œ450 quid for the full XT Groupset... will that give me a noticeable difference in weight do you think compared to much current LX setup? I heard the XT groupset just had a makeover too so am assuming it will be a noticeable uplift in the quality of my gear shifting than with the LX too? ie. am I gonna feel like i'm now riding an œ800 bike?!! lol
Cheers for your help,

Well the best upgrade you could do would be to change the forks. But a full XT groupset will pretty much take about 5-6lbs off your bike compared to the Deore/LX stuff you have at the moment.

now you've got me started...! I know the forks are a bit gash on mine, Judy 3 Rockshox, had thought about that too, my other half has Rockshox Tora's with motion control which she said I could swop mine for (not going to complain...!), but they are only for disc brakes and i'm on Avid v-brakes at the mo. Would the forks make more difference to the weight than replacing the whole groupset do you think? If so, what forks would you recommend if not the Tora's? ie. is there a certain price bracket I should be looking at to make a decent difference when upgrading from the Judy 3s? (anything more than a fiver would probably be an improvement on the Judys ;-o)
thanks again

You need to move away from the whole weight saving idea. There are three heavy points on a cheap bike. Wheels, forks and frame. Spend œ150 on a set of MX Comps and you cut out a bit of weight but, more importantly, you gain performance and control. New wheels will increase acceleration. You're not going to change the frame as its quite decent. Hydraulic disc brakes also make a huge performance difference and they are worth their weight in gold.
To summarise:
New forks as an essential.
Brakes and wheels as an excellent performance and weight saving upgrade.
Gearing will save minimal weight and, realistically, minimal performance upgrades either.

On upgrades? Pay someone œ90 to take it away.

legend... see, this is the type of advice of been needing for the last 18 months!! Cool, so I can upgrade forks, the Marzocchi's look nice too. With the wheels, i've got Jalco rims (never heard of myself and can't find much info on them) and i'm not sure on hubs etc, Tioga XC factory tyres. Do you have any suggestions on good upgrade for my wheel setup pls, I know v little about wheels, like the look of green 'spank' rims though! Ideally disc ready hubs i'm thinking, would have to save for a bit to afford new brakes too!
cheers you've been v helpful. Great to have someone who knows their stuff!0 -
Get some quality wheels that will last. Shimano XT on Mavic XC717 rims will just run and run. I'm using them and they are pretty decent. Make sure you buy the V-brake compatible rim if you are going to use use Vees for a while longer.
