I am looking to upgrade my F4 this year and was wondering if anybody had any suggestions. I would like to put a new wheelset + tires on, and chain rings + Crank + Chain rings. Can you put a hollow crank (outside bearings) on an F4? Any recommendations on parts and things to look for?

Yes, you can - and probably should - put an outboard bearing type of crankset on it. That's a Caffeine frame, very sweet frame and worth upgrading if you would like.

In my opinion, wheelset and crankset right away. Wheels will make the biggest difference in how the bike feels. For the crankset, go Go XT or Stylo 3.3 OCT, for example. If you're looking for weight savings, the seatpost, bars, cassette are all candidates, too.

The Juicy 3 brakes get mixed reviews. Personally, they feel fine for me, except the lack of adjustment can be frustrating.

If you want a quality feeling cockpit, upgrading the shifters can make a big difference. Those X.5 shifters look like they're make out of a GI Joe action figure.

For comfort, grips and saddle.

I underwent a 1x9 conversion a few months ago on my '09 F4, and part of that was upgrading the crank to a Shimano SLX, which was a substantial upgrade. Way better feeling than that Octalink thinger that came on it.

For what it's worth, I went SLX because it's damn near as good as the XT crank for a lot less money...

Wheels will definitely make a huge difference in feel, but I'm content with my stock wheels until I break them. And until I lose 20 lbs and improve my skill.

Here's a closeup of my drivetrain upgrade. All at once, I went with a SLX crank, e.Thirteen 32 tooth ring, Sram X9 shifter, Sram X9 short cage derailleur, and an MRP guide:



You will notice a huge difference going from X7 or X5 or whatever we had stock, up to an X9. Don't bother with X0 unless you really give a crap about the few extra grams, cuz the X9 will perform basically the same from what I understand, plus cheaper by far if you break it. My shifts are super quick and smooth now.

Oh, if you're sticking 3x9, the rings that came with the SLX crank were nice. But I'd totally upgrade the shifters/derailleurs before the brakes.

almontebarnes - i will probably get a new wheelset first and tires. Tires are worn out after the past year and my back tire has a loose spoke that can't be fixed. A crankset will probably be next..what do you think of the cannondale.... si i think? Brakes are fine for me, no problems here.

XJaredX - The crankset looks good. How much weight savings can you expect? This is my first bike and I like the shifting of x5 & x7 combo. Is it much of a difference to go to x7 x9?

Thanks for you comments and suggestions!

Well, it felt like a hell of a lot, but I also dropped two rings at the same time. But it just feels way more rigid, seems more efficient.

If you like your shifters/derailleurs, then I would say keep them until you find yourself not liking them or they break. But there is a much crisper and quicker shift when I went to X9. I dunno about going to X7.

check ebay

i would replace the shifters and crank set first off. on my prophet i went over the bars when a freeking tumble weed came down a hill and i just happened to hit it. i broke my X7 shifter and decided to upgrade them. the X9 are very very crisp. i also wore out my stock crankset and got an XT crank set and i noticed a very very large improvment on how my bike feels and how i am able to get the power down as well. Check ebay for an wheel set because the stock wheelset are Crap. i pank caked my rear jumping off a 1ft drop.

Upgrading the wheels would make the most noticeable improvement, but the most expensive.

A handbuilt set of Mavic 717 rims on XT hubs is the way I would go for a medium/high price wheelset.

I wouldn't buy a set off ebay, because many of the gray market wheels are from China. Your durability may vary with your mileage...
