Hiya,

Just about to gear up my Rig for some high milage action and I wondered at what position I should set the EBB. I appreciate it's going to take a bit of fine tuning, but I'm after a starting point.

I seem to remember reading somewhere that 2 o'clock, looking at it from the drive side, was right. I'd like to get it as low as possible but obviousley I'm going to be restricted by the front mech position.

Anyone out there done this already and would like to help me save some time?

Cheers

VC

PS. I don't want to run (and can't afford for that matter) a internal geared hub.

It was a bit late to call and I thought if you were up you'd be on here anyway. 🙂

Well, were's it at then?

Does it matter? Can't you choose according to whether you want a higher or lower BB, or steeper or shallower effective seat tube angle (BB to middle of saddle rails).

I'm going to be doing the same thing shortly, and I've been thinking along those lines. Where does the 2 o'clock position come from?

edit: ah, just read the bit about the front mech. I was thinking 1x9 and not considering that.

at about 8 o'clock looking at the non-drive side

need to go low enough to prevent chain suck and high enough to clear chainstay with the mech

The front mech issue is the crux of it.

Big n Daft has mentioned that he got more chain suck in some positions than in others, although that could have more to do with his shonky spannering than anything else. 🙂

I was after collecting a few "known good" positions from people who have actual geared one of these bikes up to kick off my own experimentation.

I had to swap front mech's as the bottle cage bosses restricted postions in my large frame

more to do with his shonky spannering than anything else

how many bikes do you have "off the trail" in the bike cave?

PS. Can't run 1 x 9 as I'm running a custom machined XT cassette (the lower 5 gears) on a Hope singlespeed hub. I'm trying to avoid having to buy a new rear wheel, whilest keeping the stonger wheel build of the SS hub (due to the wider flanges).

Actually, I'm doing alright. Just the Rig in bits at the moment and up until about 2 hours ago that too was ridable. It's in "mid fettle" now, so to speak.
