Last year I purchased an older Cannondale R500 (did a Triathlon on it!) to give cycling a try and I was hooked. So I recently picked up this 2016 Giant Defy Advanced Disc (demo bike) for a great price. This is my first "proper" bike. First time riding in clipless pedals and shoes, first carbon bike, first bike with shifters on handlebars! I chose this bike because it was a great bargain, came with good enough components, comfortable for long rides, and would be a great all around bike for me to ride in all terrains.

Having stalked this site for a few months, I have been itching for a few upgrades. So far, I have only adjusted the stem/fork tube length, seat height and recently added a Giant Carbon cage. I would like to shed a little bit of weight (hoping for <17lbs) and have some ideas for now:

Carbon Clinchers (Chinese/Taiwanese) - I am 68kg and with disc brakes i'll take my chances for the price
Tires - maybe slight weight saving
Giant SLR Carbon handlebars - the stock handlebars are wide for me (i think i can go narrower 40cm and lighter)
Stem - after new handlebars I'll see how that changes the geometry and position and maybe go for a carbon stem
Saddle - if I don't find the stock saddle to be comfortable

First priority will be wheels. I know the stock wheels are pretty sub-par, but to be honest, it's more of a aesthetic and cool upgrade for me. I'm no pro and not competing so this will just get me more excited about riding. I've been researching different companies and have narrowed it down to a few reputable brands, but any advice is appreciated - 38mm, 24H, sapim, axle size?

Welcome to the forum! I've had good luck with Farsports carbon wheel and ED hubs. If you search they have had some issues but what company doesn't? It's what they do after the problem happens.

BTW Nice bike!

thanks Juan...

for those that have upgraded the stock Giant SL handlebars, any favorites or is it personal preference? i definitely need to go narrower for my body frame and can get the Giant SLR's for a decent price. any thoughts?

That's an awfully sharp Giant. Welcome to cycling! Not surprised that you're addicted - just like us.

No need to justify upgrades with us or me at least. If it makes you happy and ride more, then hell yeah go for it!

The saddle is an anchor. No two ways about it. Think you'll find loads of mainstream, padded options in the 200-250g range.

if you go for farsports clinchers, i would recommend DT Swiss hubs, either 240 or 350(cheaper) as these (as well as being great quality) are easily convertible from QR to thru axle (more future proof). They also come in centerlock(much more convenient) or 6 bolt options.

Congratulations on that new Defy! I've build a few Giants over the years, and I can give a few additional recommendations

Stem: Pro Vibe 1.25in - one of the more lighter ones around that are OD2
Handlebar: An UD handlebar should be around 180g or less
Rotors: Ashima Ai2 140mm - I saved some grams here

quick update...i pulled the trigger on a few items: Deda Superleggera RS Carbon handlebars, Serfas Phantom Carbon saddle, 2.5mm lizard skins. Pics and weights to follow!

I was looking at the Ashima Ai2 Super light rotors. Giant says my stock rotors are 160mm. Could I go with a smaller rotor size (140mm) without issues? There is ~5 gram difference between the 140 and 160mm.

And for wheels, I have a few options...

https://www.wheelsfar.com/cyclocross/25 ... elset.html
https://www.lightbicycle.com/carbon-38m ... ncher.html

So far I've decided on the 25mm, 38mm depth, 700cc clincher. Farsports are getting pricey at ~$720 shipped, however they come with dt swiss 350's. Light bicycle carbon wheels were slightly cheaper but with Novatec hubs. They ebay (speedcarbon11) wheels were REALLY cheap and come with Novatec's as well. Since I'm gambling on these carbon wheels, I'm thinking of going with ebay (speedcarbon11). At ~$420 shipped, the price is significantly cheaper than the others.

I'd agree with above... lots of weight to be saved with the saddle, even without going toward anything extreme. I don't think you'll find any significant weight savings with stems, without going for something really costly and extreme. Wheels, tires and tubes will be the biggest change.

Serfas phantom saddle is in! Weighed in at 162g, 3 grams less than advertised WOOHOO!

Yeoleo 38mm carbon clinchers have been ordered. Although the "no decal" set will take 25 days until it's shipped out. By that time I should have the Deda bar on and taped up.

I wanted to know what the stock seat weighed. i might consider changing it if the comfort isn't there (342g)

new wheels came in...I haven't been able to ride the bike so I wan't to give it a few K's before I write a review. but at first glance, these wheels look fantastic. well packaged, clean weaves, no blemishes, true, etc. My only negative comment is the weight. They are not as light as I thought, more to come...
