Derailleur Comparison

Hello all,
I'm looking to buy a hybrid bike in the sub $1000 range. There are a lot of options (I've narrowed my search to *only* 13 different bikes) and the only difference among them that I can't yet reconcile is the make and model of the derailleurs. I've searched a lot of forums and manufacturer's websites but can't get a good idea of what's better and why. I'm hoping someone here can tell me how each of these models stack up, thanks in advance!

Shimano C102
Shimano Alivio
Shimano Deore
Shimano Altus
Shimano C051
Shimano Tourney
SRAM X-5
SRAM 3.0
Microshift RDM-35
Sunrace FDM34
Sunrace DLM33

I see two or three different lines of components referred to, assuming one is better than the next, but don't ever see WHY it's better. Does it work better? Last longer? Lighter? Stronger?

Example: "I wouldn't get anything below 105 components buying new."

On the shimano- the best out of that lot is Deore- but Still not very high up on the Grade stakes.

BUT is all the bike Deore? You normally find that the main part you can see is the high spec. part- such as the rear derailler. Front derailler and crankset could be something completely different. And the shifters could be a shimano part with a number that does not correspond to anything I understand.

But within Shimano--I would go Tourney--Altus--Alivio-Deore. Alivio and Deore are not bad- The rest and you would be upgrading in a short space of time. But saying that- I have 12 year old bikes that are running Altus and they still work OK. Probably because they are not used much. And MY XT equipped MTB has an Acera front mech. Could not see the sense of going that low on front mech but after 9 years- it still has not been upgraded and still works fine.

My concerns would primarily be with durability; which will last longer / need less maintenance. I'm not too concerned about the weight of the derailleurs. Thanks again!

In that case- I would go Deore. But watch out for the cranksets fitted to some bikes. This is the obvious downgrade manufacturers fit- and the parts that will wear out are the Bottom bracket and the chainrings. BB is easily replacable but not all cranksets have replacable rings.

My stepdaughter's hybrid has Alivio. It seems to be holding up fine but needs adjusting more than my much more expensive Ultegra components.

Up to a point, the better components are better quality and finish. Sometimes lighter. Past that point, the parts get lighter and the finish is better but they are for the racing crowd and may or may not be as durable.

You want to buy a new bike with nicest components you can get because it costs a lot more to upgrade them later. I'd rather have an all aluminum frame with nice components than a aluminum and carbon fiber frame and not so nice components.

Thanks all, that helps a lot with the Shimano stuff. Anyone have any experience with the Sunrace, SRAM or Microshift equipment?

Lately, on hybrids in the $2000-range, I see Tiagra more often than Ultegra Shimano's. Seems the near $1000 hybrids are now headed for Deore RD's. They used to be with Tiagra's. Having utterly customized a Trek 7.5 FX, I became very interested in hybrid bikes and have learned everything I can about them. Still am.

What I suggest is looking not at the components, but the frame. The selection of components seems to be staying lowish-end or heading that way. A good frame will get you further than the best RD. If you want the best RD, but prefer not to spend the money, how about a Shimano Ultegra RD-6500 GS for under $40? Brand new. The keep the RD that comes with the hybrid as a back-up. Here's a link to the $40 Ultegra-find:

I would guess SRAM X-5 is around Alivio quality (one step down from Deore), maybe a little better. I think their 3.0 stuff is closer to Shimano's C102 (low end, but it works).

This is how the SRAM line compares to Shimano:

SRAM X-5 = Shimano Deore
X-7 = Deore LX
X-9 = XT
X-0 = XTR

X-9 and 0 are actually a touch nicer than their respective Shimano equivalents. Really though,once you go below Deore/X-5,you're talking cheap stuff. Not necessarily junk,but not high quality. Can't speak to the Sunrace and Microshift,but I doubt they're on the level of lower end Shimano/SRAM.

Honestly, all of this stuff works. I would avoid Shimano Altus and Tourney, and probably the microshift/sunrace stuff, but all of the other stuff (Shimano and SRAM) is just fine.

A much better thing to focus on in a bike is fit. Test ride everything you can. Bike fit is extremely personal, and similar-looking bikes can fit dramatically differently. You might shave a few grams from one component group to another, but a bike that fits well makes a much bigger difference.
