My wheels will be here tomorrow (Williams System 30s not Soul S2.0SLs) but i have a problem i need to weigh my bike and the hanging scale at work is broken and im not sure when they will get another. So i figured i need to get my own scale to weigh my bike as i upgrade it. what scale do you guys recomend?

To save more weight you could put a longer stem on the bike and get a more low and spread out position. Its the same theory as walking across thin ice, rather than stand up and walk, you lay down and spread out to make yourself as light as possible so the ice doesnt break. On a bike the same applies, lay flat and low and you will find that effectively you reduce your overall weight considerably.

Ive got a 140mm stem on my bike for that reason and it is noticable faster when blasting along at full power.

If you're concerned about weight why did you buy Williams wheels?

well i really needed a bomb proof set of training wheels but i did want a simi light set. i originally ordered a set of Soul S2.0 SLs at 1330g but i couldnt ever get pay pal to work right to pay for them so i ended up going with the Williams System 30s. i could have got the System 19s but i also wanted something simi aero as well.

i plan to get a set of Williams carbon 20s if i like the system 30s as a climbing only wheel and also a set of 38s to race on. so i really wasnt going for just weight savings alone with this set of wheels.

from what ive read though the system 30s rim isnt that heavy (about the same as Souls S3.0) so id say that most of the weight difference is in the hub and maybe some in the spokes between the two anyways.

im not sure how that would save any weight but i do ride in a very agressive position. when im in the drops i have a flat back profile. not to mention my stem is fliped and i dont have any spacers to remove. i thought about getting a -17* stem but i dont think it would help me any as i can achieve the body position i want now.

i will also add that i weight 120 so i cant loose weight either. the bike with me on it in full gear weighs 136lb total.

uh, no.

I tried this on my weight scale and I found I dropped 4 lbs. Thanks for the tip! I feel noticeably lighter now.

Uhhm, that does make you lighter. It may make you more aero and thus faster....but not lighter.

Actually, by theory of relativity, I think by making you slightly faster in effect you might even be a smidge heavier, but we'll keep quantum physics etc out of it.

srsly??? The reason you spread out on ice is that so your weight is as evenly distributed over the ice as possible. That helps you avoid concentrating too much weight on any one point of the ice so you hopefully avoid the ice cracking, plunging you to your death. Your weight hasn't changed at all, only its distribution.

On a bike, this may make you slightly more aero if you can be comfortable in the position, but you still weight exactly the same.

I post this question to people about tires:

What is the difference between Michelin Pro Race 3s and Michelin Krylion Carbons?

Also nice job with the bike slimming, how much did it cost?

USE alíen seat post at 140 grams or so

Oh and full carbon 100gran saddle off of eBay for $50

I understand the bike "slimming" and all...and I really do like the choice of products and new parts, etc. but is this in an attempt to just build a light bike or to go faster?

The same $ spent on coaches/trainer/clinics would have yielded probably the same/more weight loss and an increase in speed, knowledge, etc.
$1000 in cool parts is just that.....

Shame everyone else already covered this. There is just so much wrong with this post.

I was going to mention you can save some weight (at a decent price) by looking around for seatposts. Just don't go by claimed weights- they're usually wrong. Carbon saddles will work if your butt adapts well to them. Don't remember if you went for a lighter seatpost collar- new ultimate has a nice one that's about 7-8g that I use on my bike.

I'd say you may have already made a mistake with those wheels if you're shooing for under 16lbs. Performance bike had Reynolds 32mm deep carbon clinchers for $600 something over the past few weeks, and they weigh in at 1410g. I think they've just recently sold out.

Also, a 50g tube may not give you the longevity you need. 80g tubes seem to be a sweet spot for weight/robustness for me.

Cheapest Speedplay pedals ($120) + Wards titanium spindles ($55) = 160g total for both pedals. Plus you get speedplays!

No its just shaving weight off one of my bikes.

Not really on topic, but the Krylions are good training tires and very flat resistant.
The PR3's are excellent racing tires, much better performance but much more flat prone and will not last nearly as long.

If you want the best of both worlds, of course you could/should get conti GP4000s, they are very reasonably priced if you get them from the UK sellers (PBK etc).

M_FactorX19

yeah i think you are right about the wheels they came in over weight too. so im not sure if i will get to <16lb with them or not. i really just plan to use these to train on though so im not to worried if they ride good but i do plan to get a set of 20mm carbon clinchers and a set of deep carbon tubies.

as far as tubes go ive had good luck with light tubes. normally if something is going to go threw the tire it is going to go threw the tube you know.

i have a set of speedplays and dont really like them so ill stick with these for now but thank you for the sugestion.


i though about getting a carbon saddle but since i got the SLR Fibra for so cheap i went with it. it only weighs 135g so its not that heavy. its very comfortable to boot.

i do plan to get a new seat post but im not sure witch one yet. i also plan to get new bars and a stem but i think i am going with the 3T team combo there. i might even get a 3T seat post to keep it all the same but im open to new ideas there.

after that i am going to change out the group. ive pretty much made up my mind im going with a Force group but might get Red if i find it cheap enough. after that i plan to work on the small things like seat collar, bolts, etc. i still think i will be able to get under 16lb after that but i guess we will have to wait and see.

Of course, many people on here are on day 40+ waiting for their PBK orders right now. I'm at 30 days today since my shipment notification. Some on here say they're waiting for their orders from early Dec!

M_FactorX19

So far i really like the PR3s they are very fast and grip well in wet and dry conditions

as far as the cost goes im probably right at $1,000 on upgrades so far but will likely spend that and a little more before im done. i hope to have most things listed above done in the next 2 months or be done before the first race this season

M_FactorX19

added a few more parts so i figured i would add to the post.
items include: new Williams System 30 wheels, new SRAM cassette (only temporary), and Rox Ultralight Rim tape for the wheels.

Rox Ulralight Rim tape. this stuff is crazy light mine weighed in at 3g a pair! so that saved me 45g from the intalled tape on the Williams wheels.



Cassettte isnt anything special since i am only using it for a sort time till i get a new group but i wanted to try a new gear raito so i would know more what i wanted with my new group. it is light than my old cassette but im not sure by how much yet off claimed weight of old cassette 60g lighter though.


Williams System 30s (also posted in Williams wheel thread) they weigh in at 1620g with the Rox tape. they did still save some weight though (280g) not the full lb i would have with the Soul wheels but still a savings and i plan to get some lighter Carbon wheels soon and use these for training. its an amazing smooth rolling wheel and i could tell a huge difference in holding speeds 20+mph even in strong head winds today not to mention how much stiffer they are over the old Alex wheels on before(more pics of wheels in Willliams wheel thread)


The bike as it sits now.



stay tuned as i should have a lot of new upgrades comming soon. i plan to order a new chain tonight but im not sure if i will go with the KMC X9SL or just get the X9 since i will soon be getting a new group and save the extra money for a KMC X10SL chain. I should have the new group (likely Force maybe Red/Force) soon as well as a bar, stem, and seat post change.
