I own a Cannondale Quick 4.
I love the bike and have no complaints.
...and I have some in-store credit at my lbs.

If my desire is to make my Quick faster...
Would you upgrade the tires and wheels?
or
Would you upgrade the drivetrain?
I have about $250 in store credit and am willing to add another $50.

It sounds to me like your biggest concern is going faster, and not an issue with the existing drive train. Therefore, I cast my vote for wheels. Wheels are always a noticeable improvement.

Wheels (tires).
You can upgrade the drivetrain as it wears out/play with gearing, but wheels/tires you will notice/feel immediately.
That is all.

I would also research tires... Maybe a place like this is a starting point:

Get an Easton Circuit wheelset off eBay for about $200. These are even better than the current 70 series and retailed for $500 to $600. But, if you are serious about riding faster, then just follow the great Eddy Merckx's advice .... "ride lots". It will pay greater dividends.

Tires (700 x 28 ish), compact road crank, shorter BB to correct chain line, and Shimano R440 front derailleur (road bike radius with mountain cable throw). Depending on choices should be $250-300. BB will prolly be a 107mm length.

The OP said he had store credit so I don't think ebay purchase suggestions help. I could be wrong however.

A computer with heart rate and cadence. It'll help you upgrade the engine.

I usually don't bother "upgrading" anything on a bike until it's broken.

Talldog

Oops ... right you are, although $300 at a brick & mortar LBS won't get one much of a wheelset.

You got me looking for Circuits by the way. I have Easton EA 50's now and really like them, and I know that the Circuits should be a nice step up. Finding a deal on them gives me another reason to build another bike.

Tyres definitely - wheels maybe but at that price you probably won't notice a huge difference. Clipless pedals and shoes would probably help you acheive your higher speed goal as well.

If it were me, I'd be getting some thinner tyres (28mm will probably fit, any thinner and you'd probably run into problems), clipless pedals and shoes.

I ride a trek 7.2fx that came with 700x35 invert tread tires ( wire beads) that would max at 80 psi. My fastest average for my daily 21 mile loop was 14.5 mph. I swapped them out for 700x30 almost slicks with kevlar beads that inflate to 100 psi. I now average more than 16 mph and didn't sacrifice any stability or comfort. Skinnier and harder will be faster and you can spend the rest when you need to fix something.

I also say go with tires.....and clipless pedals and shoes.
This tire comes in 28,32 & 35 pick your poison and have fun.

The important thing is the 'SPORT' in the name....

Thanks for all the info.

Do you think upgrading to these very affordable wheels would be a noticeable improvement over the stock wheels on the Quick 4 (Rims - Element Xero C3 Wheelset)?
