I weigh 130 and race xc.
2002 Jamis Dakar Pro
02 Manitou Mars Super
XT cranks, front derailler, and shifters
es 70 bottom bracket
xtr rear derailler

I am willing to spend around 400 dollars to lighten it up. What should I do? |
| Do you know how much it weighs now? | AZ X-Racer
Jan 20, 2002 10:26 AM | | The new Jamis Dakar frames are NOT light. They went to a cheaper and more freeride-ish aluminum instead of the Easton Elite they used to use back in '96 and '97 (I recently had a '97 model).
That said, if you are going to race, I'd look at using Stan's liquid latex tubeless system with your wheels and trim almost a pound of weight by using lighter Hutchinson Air-Lites or some other sub-500g tires. You can also use your money to build a new set of wheels to save even more weight.
Next, save up to get a new frame and sell the one you've got--maybe next season(?). I believe that frame is nearly a pound heavier than most of the 5.5lb racing FS frames that are on the market right now. The old Dakar Team (small) used to weigh just around 5 pounds even (some were a bit less, some a bit more). A Santa Cruz Superlight, a Giant NRS Air or a Specialized FSR will each weigh in around the 5.5 pound mark, are proven race designs and wouldn't break the bank. The Titus Racer X and the Ellesworth Truth are in a higher cost bracket, but are also in that weight range and are excellent frames.
The rest of your parts are probably OK and would be very expensive to start replacing. You could potentially save another 1/4 pound or so by going with a different crank and BB combo, but it won't really be worth it. If you were starting from scratch I'd recommend it, but the XT cranks are excellent. The lack of a lighter BB choice is the only bad part about that system. You could lose another 1/4 to one pound by changing yor bars, stem, saddle, seatpost and other small parts and bolts--but it will cost you. |

Jan 20, 2002 11:30 AM | | with that kind of money, I'd start off replacing the grips. OUry grips are 100g. titec porkgrinds, for 8bucks, are only 16g. without the end plugs. I don't know about the rest, I'd say get new super lightweight tubes, but you have UST. python tubeless is really heavy, loook into getting new tires. what else....thomson stem is also really heavy. Ritchey WCS stem is around 80 bucks...it's 125g. vs. the thomson that's like around 200g. (keep in mind that you can sell the old parts and decrease the cost of the new part) terry fly is 245g~! a flite TT (89.98 @ pricepoint.com is only 165g) how about the handlebar? If I were you, look at the Bontrager Racelite set. VERY VERY LIGHT wheelset, tubeless compatible. some guy's selling it right now for 425. but I don't think it's worth that much...may be 300. I have the older racelite set...non tubeless with king hubs...awesome. any questions..just ask. |

Jan 20, 2002 11:55 AM | | Will replace with Kore Elite flat bar(20 bucks, 140 grams) and get the titec foam grips. That should save around 200 grams for 30 bucks...not bad. Where can I find the pork rind grips? |

Jan 20, 2002 12:15 PM | | You can get the grips directly from Titec.com or you could save some shipping and buy them from Cambribike.com with some other parts that you may need. Titec.com also has some good handlebars and stems to check out.
My Ritchey WCS 100mm stem weighs exactly 139g...
I stayed away from the other parts and concentrated on your wheels, tires and frame because those are huge issues and you won't feel 200-300g elsewhere as much as you'll feel it in your wheels. The others have good suggestions too, but go with the wheels and tires first... |
| Agree..... | scream5204
Jan 20, 2002 2:31 PM | | AZ X-Racer is right, go for a new wheelset. Most important area to save weight. Crossrocs are beastly heavy. But yeah, the grips and handlebar are a great start. any more q's just post. |
| Another grip option | dlk
Jan 20, 2002 2:44 PM | | Grab On makes a grip called the "Leisure Sport" that weighs about 18-20 grams a pair (without endcaps). The pair I just bought weigh 18.5 grams (28 grams with end caps). If you don't like the angled shape of the Titec Pork Rinds, the Leisure Sport shape (very similar to the Grab On MTN-1) might be a good alternative. Got mine here:
http://www.ultimateridingsports.com/handlebars9.html
A note of caution: If you buy the Leisure Sport grips thinking they'll be the same as the Grab On MTN-1 grip only thinner, you'll be disappointed. The Leisure Sport grip is made from a completely different kind of foam - less dense and much softer than the MTN-1 (which just happens to be my all time favorite grip). |
| U may lose more than weight | Re-Pete
Jan 21, 2002 1:15 AM | | Swapping out your bars to save 150 grams sounds graet in theory but you may lose more than weight
If your happy with the fit and handling with your risers you may lose more time than u gain (if your looking to gain time that is)
Switching from such a great bar to a flat may have its negatives but if you want a light bike for the sake of having it and the ride is secondary go berserk
On the other hand losing weight in your wheels is unlikely to have any detremental effects unless your UST is saving you from fixing flats
Good luck |

Jan 20, 2002 11:59 AM | | Good point by Scream. You can stretch that $400 dollar mark by selling your existing parts. For example, I'd start by selling that Crossroc setup. You might get $250, $300 bucks out that deal. I'd then parlay that into a nice set of lightweight hubs such as American Classic ($300 total through Cambriabike), some good lightweight rims, and have a reputable builder build you up some nice wheels with lightweight spokes such as DT Revolution or the equivalent from Wheelsmith. Total cost of having the wheels built would be in the neighborhood of $500, which, substracting the $300, leaves you with another $200 to play around with. With the rest of your dough, you can still go tubeless by trying a Stan's setup for about $25, get some good lightweight tires, and you might even have enough money left over to pick up an Easton Ct2 off of Ebay for $35.
Good luck. |
| Please weigh it! I'm dying to know | calgracer
Jan 20, 2002 6:33 PM | | I have the exact bike on order and I should receive it in the next week or so. Jamis says it should be around 25.75lbs. It should be really easy to take 1-1.5lbs off this bike with minimal cost. Tires, bar, seat, and stem should more than accomplish that weight reduction. |

Jan 20, 2002 10:51 PM | | Talk to Mike at www.oddsandendos.com He's a great guy and will set you up with a really light, custom built wheelset. |
| If you're looking for a light wheelset.....absolutely! | pedalinbob
Jan 21, 2002 7:32 AM | | and, you can go with python airlights ($20 each) with ultralight tubes or stan's system...
weigh you current wheelset and tires, then go to oddsandendos.com to see how much weight you might lose with another wheelset.
your tires are much heavier than the tube version--python airlight, which weighs 480g.
between tires/tubes and wheelset, you might lose a pound of rotating weight...
use the mavic tubless as an extra wheelset or for another bike/training...
