Jan 18, 2002 8:03 PM | | -I would start with the wheels as the UST tubeless wheelset (1600g)/ UST tire combo is about 600g heavier than a regular lightweight wheelset with race tires.(on my wheels the difference was 750g which is a DAY AND NIGHT difference.my s-works HT felt terribly slow with the UST wheels.after the change it was a rocketship.)
-QR`s.Mavic QR-levers weigh 113g/pair.Ti QR`s weigh around 80-90g.I`d suggest you steel bolt on axles (no QR) which add stiffness and weigh only 65g.Ti ones are even 48g but too flexy.
-Stem.last years s-works stems were well over 200g (120mm was 212g).Ritchey WCS or some Euro Stems (FRM,ITM,Extralite) are around 130-140g.
-grips.S-works grips weigh a heavy 85g.i prefer rubber grips over foam but those Bontrager foam are lightest at about 18g/pair.my Pedro`s rubber grips weigh 49g.
-remove gear display on shifters (-23g)
-the Handlebar weighs about 150g.lightweight handlebars are around 100-130g.
-Saddle.s-works saddle weighs about 260g.get a Flite TT (163g) or SLR (135g).
-Thomson seatpost is nice but EXTRALITE is lightest (www.extralite.com)
Extralite (290mm,Ti-Bolts) : 175g
Extralite (290mm) : 178g
Extralite (380mm) : 215g
Thomson Elite (290mm,Ti-Bolts) : 210g
Thomson Elite (290mm) : 213g
Thomson Elite (310mm) :247g
Thomson Elite (410mm) : 273g
-Exralite seatpost clamp weighs 14g (s-works about 50g)
-XTR-brakes weigh 380g.Avid Ti`s are 322g (tuned Avid Mags as low as 280g)
-the s-works strongarm crankset isn`t lightweight (656g incl.fixing bolts) and it needs the heavy XT splined BB (256g).some light crankarms such as Race-Face with Sugino supershifter rings make for a 580g crankset.combine this to a Ti BB (140-160g). |
| A few notes on that... | eric wictor
Jan 19, 2002 8:01 AM | | A friend of mine is looking for a new crankset for his FSR and we were discussing it down at the shop today.
Here's the problem: you can't get just any BB because you have an E-type derailleur. When you get your new BB, get one with a cup on the drive side. In the case of RaceFace, this means you have to order a DH cup.
Or maybe you already knew all this!
Oh, I would never dump the Thomson post for 23g savings. It's the strongest out there, and there are much better places to save weight. |

Jan 19, 2002 1:39 PM | | the Extralite post is 35g lighter and i never had any problems whatsoever.all a post has to do is hold the saddle in place.Thomson has a good reputation but part of it is a good marketing.the stems are way overbuilt but if you like that bulky CNC machining then go ahead.

Jan 19, 2002 11:59 PM | | It seems we have a couple of people who are staunch defenders of Thomson, regardless of what others say. I guess I'm one of them.
I don't know what Thomson sells for in the rest of the world, but when I bought my stem and seatpost them were about 250 EUR together. I'm not going to replace a part that has proven itself to be one of the best in terms of quality, just to save several grams. On the other hand, even though I'm not heavy at all (70kg during winter) - I am very hard on the bike (lots of urban and even trials type stuff).
As for the Extralite seatpost, I loved mine and bought a second one for my FS (before I found out it was too short and ended up with a 410mm Thomson). But this autumn, I found out the one in my hardtail was bent. Though this may have been due to damage to the seat tube, the question in my head is "how long until it would have broken?". Not that Extralite posts in my view aren't good, but unless you goal is building the lightest bike at no cost (financial or otherwise), I see no point in using an Extralite to replace a Thomson. |

Jan 20, 2002 1:18 AM | | how much could he save if he kept the wheelset but converted to stan's tubeless and ran regular tires. seems like it would be a cheap way to lose a pound |
