2 lbs. vs. better components(11 posts)

2 lbs. vs. better componentsStrom
May 8, 2001 2:07 PM
Thanks to all who have given me advice in my bike hunting exercises. (I'm looking for an all--purpose bike to use primarily for commuting, 10 miles each way.) I've got it narrowed down to the Specialized Sirrus Sport and the Jamis Coda. The Sirrus is fast and light (700x26 tires, aluminum frame, about 23 lbs.). The Coda has better components (XT vs. Deore, and a Rock Shox seatpost), but it's a litte heavier (about 25 lbs.). The Coda also has wider tires (38s), so it doesn't ride as fast. I'd probably put some 28s or 30s on it if I got it.

They are about the same price ($700 vs. $750). Which would you go for -- the lighter weight, or the better components?

Sounds to me that you like the Sirrus a little more. You'll wear out the components anyway, so why not just upgrade them as they wear out with the better stuff? Then you have the lighter/faster bike to start with.

Typically the bike with the better components weighs less. since it's reversed in this case the wheels and frame must be really piggy - gotta save $$$ somewhere. I'd go for the lighter bike then upgrade to better components as needed. The other thing to do is to have both bikes actually on a scale in front of your own eyes - it's not unusual for actual weights to be different from published weights, remember the part where the brochure says they reserve the right to make any changes when they want?

I think the weight difference is due primarily to the Coda having a steel frame and the Sirrus having an aluminum one. Unfortunately, the bikes aren't at the same store so I can't compare their weights directly. The Sirrus was weighed at the store where I saw it, and the Coda's weight is a published one, and supposedly (according to the person at the shop), an accurate one. The Coda does feel a little bit heavier, just from lifting them.

Well, steel frames do tend to be heavier, but they are a bit more bomb proof. Problem is you'll have the frame for a long long time and have to haul that weight up every single hill. I cringe a bit when I hear weights like that - my full suspension MTB weighs in at 24 lbs., but then the cost is something else.....

2 lbs really is a lot - a gallon of water is over 8 lbs., so a quart is just above 2 lbs. or just under a 10% difference. Now think about fixing that quart bottle of water to your bike (not your body) and hauling it everywhere you go.

My rule of thumb is that a steel frame will weigh about 1lb. more than an aluminum frame. The bigger tires and RockShox seat post will make up most of the rest. There is, however, the "weight fudge factor" to consider.

Every bike has three weights: What the manufacturer says it weighs, what the guy who owns it thinks it weighs, and what my scale says it weighs. My scale must be a little off because its ALWAYS higher than the other two. I'd be surprised if the Coda doesn't weigh about a pound more than advertised.

As a general rule, I think that bikes that are similarily priced tend to be real close in value. This tends to make me agree with Grz Mnky's original comment that the manufacturer has skimped somewhere on the frame or wheelset in order to give you a better derailleur.

You don't spend a very high percentage of your riding time shifting, but the frame is with you all the time. For that matter, I think that the rear derailleur is probably the most reliable component on the whole bike anyway.

I think I'd take the Cirrus.

I'd get the Specialized and upgrade the components as they wear out.
It sounds like you like it a bit better anyway.

Thanks for the replies! Just to clarify, I did like the faster ride of the Sirrus, but I figure that the Coda would probably be a lot faster with 28 or 30 tires than with the stock 38s. It's hard to say how they would compare with narrower tires on the Coda (that's where the weight vs. components issues comes in).

I had heard (but am not qualified to know for sure) that Jamis tends to give better value in the specs. than most. I don't know how to judge frame quality or to know where else they might have skimped, if at all, so any expert opinions would be most welcome.

I gave the wrong URL (but the correct specs.) for the Jamis Coda above. The correct URL is . Thoughts welcome!
