|I am working on getting my CX bike dialed in, and realized even before I spent Sunday afternoon cranking in 39-27 that I could use some lower gears.
My two cheapest options are:
Swap ultegra double with ultegra triple on the road bike. I have rings to run a 30-38-44. Will a 44-11 be high enough you think? Also, would I be better off using a Mtb. front der. instead of the Ultegra? This option would leave me with the 39-53 on the road bike, which should be fine.
The other option would be to put on an old LX/DX 110bcd crankset from my old mountain bike. This would give me 24-36-46, but I would possibly have to get a different BB and I don't recall the condition of the old rings of the 7 spd setup.
The last option, of course is to run 38-44,46,48, etc. and get an 11-34 cassette and Mtb R. Der. (This is what my GF has and it works great)
I know this is kind of a repeat topic, but any input is appreciated. I guess my biggest inquiry was regarding running a 44T big ring if anyone has any experience?

|Adam Craig, espoirs national champion, and Mark Gullickson, top 25 in the world UCI points, both run a single ring set up with a 44 tooth front ring and either a 12-27 or 12-25 in the rear. A 44 x 12 should be plenty big enough for most cyclocross situations.

|44 is fine in most race sit's, especially with an 11. I run 1 bike with a 11-30 XT 8 speed and it's yummy. Going to switch it to a 44 single possibly.|

|For that past season I ran (when I finally got my bike setup, otherwise I ran a 34/16 SS) 44/12-24 campy 8.
I would never think of going a chainring down, reason being that I found that I can run, with SS hands down... faster than dis and re- mount. I saw number of guys I passed re-mounting to ride a curved, steep, short down hill, and to dismount at the bottom.
I was going to space out with the wheels manu... to get campy 9 for comming season, but this only gets me an extra 26t ring, dosent help much..i need a 11/ 24?

|I guess I am not setting this bike up for a race bike (but would definately consider a single ring if I decide to race), but more as my winter mountain bike - gravel roads and light trail duty usually. I will know soon if I run out of gears for the trip on the road to and from the trail.
Bonus: I was just thinking that with the small rings up from that I won't need to switch to a long cage R. Der. either - that will be a plus for setup.

|I'm running a 46T big ring right now, which seemed big enough for race situations, and fine out on the trails.
During the winter I'm riding the roads a fair bit in the nasty weather, and having a 46-12 combo with the 23c slicks on my spare wheels isn't big enough in the hills. You'll spin a 44 out pretty easily.
If you won't be on the road much, no worries though.

|Might as well give it a try! I think the worse case scenario would be shelling out 30 bucks for a 48T big ring, but I think the 44 will suffice for now. Looking forward to having small crisp jumps between rings up front.|| |
