very very fresh to the cycling world, got a hold of an older Guru Cron'alu. Rode it once and it was great, second time around issue happened...

heard some noice from chain area, then it kinda "seized" up. got off and notice that the front derailleur was totally wrong and actually impeding the chain from moving. Thought an adjustment was all that was needed so took it into local shop (again, very new to cycling) and they gave me the bad news that since they are made as an actual part of the frame it is not something that can be replaced or repaired... where does this leave me???? need to buy a whole new frame? saw some posts on other sites and also ebay where they were like 500-600.... any help would be GREATLY appreciated

Photo of the part would help in this case

Googled the bike to check the other side, and it looks like an F-type front derailleur. Basically there's a small mounting piece that sticks out of the frame, on which the derailleur is mounted.

In the old days that piece was metal and screwed on to carbon frames, but it sounds like on yours it is part of the frame itself. If that's damaged, you could be in trouble indeed.

Blazin, the first step is to get a 2nd opinion. All too often, what one shop says can't be fixed is meat and potatoes to another.

You want to find a shop that prides itself on difficult or complex repairs. Assuming the FD mounting bracket is damaged (otherwise I can't see what the 1st shop found so difficult) it can probably be repaired, rebuilt, or cut off and a new one bolted or pop-riveted in place. Otherwise, it might be possible to use a clamp on braze-on adapter.

You need to find the local guy with an attitude that can be described as follows -- The difficult is done immediately, the impossible takes a little longer.

BTW- if you list the city of residence in your profile, someone might be able to steer to the right guy.

PLease take a good photo of the OTHER side of the bike especially where the front derailleur is. And maybe a couple of different angle shots of the front derailleur area.

I'd say not, since the bike uses an aero seatpost, and the tube seems to be a simple prism of the aero cross section. If the tube was round down there shaving off the hanger and using a clamp would be pretty obvious fix...

I like your suggestion of riveting on a fresh hanger intended for a carbon bike... not sure where you'd look for such a part, though... hit up a Taiwanese frame factory? I imagine local framebuilders would most likely only have steel ones intended to be brazed on.

Anyway, we really need pix of the carnage.

The builders buy components , so you need to read the build list to know which supplier
they bought that part from.
Guru is, just, the brand of bike, a name painted on the frame, not the component in question.

Kimmo

It's likely to have been welded on, in which case the part prolly wouldn't be suitable for riveting.

Like Henry Kissinger : " the Illegal can be done immediately, The Un Constitutional takes a Little Longer ".. ?

Heh... or like Bush, Obama or any number of lawless scumbags.

I mentioned this earlier.

If the OP would say where he lives (don't need the home address, just the general area) I or someone else might be able to refer him to someone who can solve his problem.

IMO- everything (just about) is fixable, if a bit of creativity. For example it's possible that a clamp on FD could have the band cut, and filed to fit, then glued and riveted on. Or something similar with a clamp-on braze-on adapter. Oterwise, a stock replacement part could be sourced.
