Reducing Weight on a MTB
Postby randyrob » Sat Apr 14, 2012 6:09 pm
I own a Giant Talon 1 (2011) here are the specs ==>
http://www.giant-bicycles.com/en-au/bik ... 389/44225/
or
http://www.giant-bicycles.com/_pdf/bike ... alon.1.pdf
I have got a couple of season's out of it and so far have only replaced the things that have worn or broken.
That being the Saddle/Seatpost/Tyres (replaced stock units with Selle Italia Flite XC Gel-Flow Saddle/Thompson Seatpost & Maxis Highroller tyres)
I understand it is an entry level MTB and there is room for improvements weight wise but which are the best components to upgrade first and why. The Front Forks, Rims...? any other suggestions appreciated.
Cheers Rob.

The crank could probably stand an upgrade to one of the Deore ones with the external bearing cups - would save a few grams and add some stiffness.
The forks problem probably isn't their weight - you would have to step up into the $300+ range to get anywhere worthwhile.
Wheels - maybe. but again how much do you want to spend? The better quality wheels all seem to be moving away from the 9mm QR standard so upgrading your wheels to something super tough and light also means upgrading the fork to a thru-axle type setup (worthwhile in itself).
Then you'd have to seriously look at the cost vs. flogging the bike and simply buying something lighter - there are some nice light frames coming from Felt/Scott etc. that had me drooling lately.
In short...for most mountain bikes the upgrades tend to be towards greater capability rather than worrying about weight so there isn't much of a market for super light parts.
but really, that's rubbish. We get none of it because the choices are illusory.

You have a fine entry level MTB, but the benefits of upgrades may be marginal. If something breaks by all means put on something flasher. If something isn't doing what you want it to do, then get something else, and if you really want to try out something else just for the sheer upgraditis/try it factor then go for it too as long as you don't mind spending the $$, but before you start up that path think hard about what you've got, what you want and whether you want to save for another bike altogether.
With my bike I replaced the wheels, because the original hubs were not very good and I like to build my own wheels, but otherwise the other changes have been to the cockpit so as to try dial in my fit, try different set ups etc. I've resisted the urge to buy new forks, brakes or drive train (though I did get better cranks, chain and cassette to make things smoother) because the economics just don't stack up, I think. That's not to say you will come to the same conclusion though and if you don't have spare $$ then slow upgrades as you can afford them might be your best option.

Appreciate the wise words. I hear you.
Drubie, Is this the Crankset you are referring too? http://www.this link is broken/shimano-deore-m ... -chainset/
Seems like a very cheap upgrade (current platinum price is $98) given it also comes with the Bottom Bracket. Will the difference in Ring Combo make much of a difference : 48/36/26 vs Mine 44/32/22.
Cheers Rob.

You should be able to get it with a range of chainring sizes.

The Chain Reaction link says "BB Is Included" - those cranks are a steal at that price.
but really, that's rubbish. We get none of it because the choices are illusory.

That is Awesome! Exactly the info I was after.
I've ordered the Shimano Deore Chainset 9sp M590 - 175mm 4-Bolt 22.32.44 Black.
Came to 83.72 AUD with Free Post. Very Cheap Upgrade.
I guess the original reason I was chasing reduced weight, was I notice a difference when I go out and do
a shorter loop (less than 25km) and I only take 1 Water bottle and a Tube in my jersey pocket vs when I do longer rides
and I take a couple of water bottles, a saddle bag with tools/tubes/parts etc
Cheers Rob.

Randyrob - you may need to borrow the bearing cup tool to get those cups in your MTB - although "I've been told" careful use of multi-grips and rubber straps is enough
but really, that's rubbish. We get none of it because the choices are illusory.

The other really good upgrade is wheels. Stock OE wheels in that bike range aren't that great. Spending up to about $250 in the UK for a new wheelset is well worth it. Otherwise about $400 here. A mate just left $130 with Wiggle for some Fulcrum Red Metal 10's on runout and they are a nice looking/feeling thing...

Me too - got them sitting in the shed ready to go - although you do have to drill them for schrader valves if you want to run normal tubes.silentbutdeadly wrote: A mate just left $130 with Wiggle for some Fulcrum Red Metal 10's on runout and they are a nice looking/feeling thing...

Those rims sound like a steal, i'd have to buy some 6 bolt rotors and probably a new cassette too which makes it a bit more prohibitive - But when the time comes when I have worn out my current rotors and cassette
I recon i'd grab some of these along with those parts. I know i'm on borrowed time with my rear hub - The cassette housing has a bit of play/slack in it. I also use the Bike for Touring the Munda Biddi Trail each year,
So having strong rims with easily replaceable spokes is quite important to me.
Cheers Rob.

Actually they are $118.12 Landed at the moment with the checkout code BONUS10, that's less than $60 a Wheel....hmmm......drubie wrote:Me too - got them sitting in the shed ready to go - although you do have to drill them for schrader valves if you want to run normal tubes.silentbutdeadly wrote: A mate just left $130 with Wiggle for some Fulcrum Red Metal 10's on runout and they are a nice looking/feeling thing...

probably wheelset/tyres would be the most weight saving upgrade, rolling mass as said.
But I wouldn't let it bother you too much about saving to much weight. Back in the day we were all about drilling chainrings, cogsets, barends, (remember them) waterbottle cages and even stupidly seatposts The only thing I didn't drill out was the Camelback.
I think the mid priced MTB's today are so much lighter than the high end stuff of the 90's so go out and ride it till it drops. The heavier weight just makes you a better rider in the end.
Now those cranks you got, they could do with some drilling

Do the wheels next - even if the weight savings don't sound amazing on paper, nice wheels will transform the bike.
I was about to advertise some wheels i built but haven't used. 32h XT hubs with eyeletted 450g rims. They are really nice wheels and will be around $200 with rotors which will be a steal. I'll probably put up an ad soon if you are interested

Cranks are Installed & a nice set of wheels built up by Alistair
Original Weight before the upgrades was 13.6kg, now weighing 12.29kg
Can't wait to take her for a spin this weekend.

I am a little surprised you managed to shave over a kg off it with those two changes though - way to go!

The tora would be the next place to go looking for weight savings. I think you should notice a decent difference from what you have done already though.
