'Dale Posted March 16, 2011 Posted March 16, 2011 My FD is a lil bit niggly especially shifting up to the big blade...It's okay now after some serious tech support on Saturday night before the Argus. MariusL told me that the pros most often use the Sram Force front derailleur instead.This morning, I see a review of the newest Spez TT bike and everything is Red, except for the front derailleur. Hmmm...Anyone have a similar technical niggle?
Aurora Posted March 16, 2011 Posted March 16, 2011 yup heard the same story. Force front derailer is the way to go
Bat-ass Posted March 16, 2011 Posted March 16, 2011 Interesting this SRAM red stuff..... some pro's opted for shimano cassettes and chains as well???? Shimano Dura ace is a few grams heavier for good reason.... but dont feel alone cause if you look at the Campi bikes at Roubaix... they also throw in some chorus bits and pieces!!!
Bike Mob Posted March 16, 2011 Posted March 16, 2011 been running red for two years now and only used red FD's. No problems... When you say twitchy...what do you mean exactly?

Bike Mob Posted March 16, 2011 Posted March 16, 2011 The pro's actually used a modified FD with a RED upper linkage and the Force blades for added stiffness so they could shift under immense power. That isn't really a consideration for us mortals.
MariusL Posted March 16, 2011 Posted March 16, 2011 When you say twitchy...what do you mean exactly? When we were looking at it on Saturday eve - when you shift onto the big blade the chain rams against the inside of the big blade, and doesn't seem to slide nicely from small to big blade... played around with the height and angle of the fd... but there is this sickening screaching sound when shifting onto the big blade... Airbender is running cannondale hollogram cranks and chainrings (but I don't think that is the problem).

Tiny K Posted March 16, 2011 Posted March 16, 2011 (edited) I had a look at the ride in question on Saturday afternoon. The FD was not shifting lekker and as much as you adjusted the stoppers, it wouldn't shift up to the big blade - you would have to hold the shifter to shift up for a bit longer to get it to go to big blade. Sometimes it would not shift or the shifter would get stuck. After me, he went to MariusL, and they 'turned' the FD to make it shift better..... it could be the shifter or the FD.

AndreZA Posted March 16, 2011 Posted March 16, 2011 They (the pros using Force FD) say the lightweight Red cage flexes under pressure when shifting and that is why they go Force.
'Dale Posted March 16, 2011 Author Posted March 16, 2011 On the race, I had zero issue after some adjustments made on Sat eve.It was smooth as I am used to it.It had to be 'ridden in', I guess. Have been off the bike and in jet planes & boardrooms since.Hope the niggle is gone. Thanx again, SirK and MariusL and James. Thanx for the views, riders...

Airbender is running cannondale hollogram cranks and chainrings (but I don't think that is the problem). Are you sure the rings are installed in the right "orientation" they need to be in specific areas so the ramps and pins "pickup" the chain properly... May be that... also at very low "mechanic on a bench speed" they sound dreadful, but when riding at the right speed they pickup much faster

'Dale Posted March 16, 2011 Author Posted March 16, 2011 Agreed, Tarmac... With momentum and wattage in riding, it felt good. I will keep an eye on it. Mampara, useful info. I luv having Red all round. Wanna keep it that way!
Bike Mob Posted March 16, 2011 Posted March 16, 2011 I run red and switch between 53t and 54t blades without even moving the FD. No fidling on the fd required.
