yeah I've tried all those things. I'm familiar with the limit screws & the like, & have adjusted front derallieurs several times in the past (I do almsot all my bike maintenance myself now), but I think its got to the stage that the derallieur is really stuffed. The rest of the running gear is in good condition, clean, lubed, not clogged up with crap.
The chain only comes off back-pedalling since I removed the front derallieur (it never used to).
I'm just wondering about 'fixing' the front chainring as a means to avoid replacing the derallieur - like I said, I hardly use the other front gears so just having 1 front gear will be ok.
I'm almost tempted to convert to a single speed machine, but I gather that will mean different hubs & changing the drop-out's to ensure chain tension?

either that or buying a chain tensoner http://cgi.ebay.com.au/Surly-Singleator-Single-Speed-Chain-Tensioner-New_W0QQitemZ7189322474QQcategoryZ7295QQssPageNameZWD2VQQrdZ1QQcmdZViewItem
this way you can run verticle dropouts and maintain chain tension....
try 'spoken' off ltl bourke near paddys.... they have no name ones for like $15 dollars....

If any of you are going to come to Nati for the Frinj, ensure you pick up one the Town Bikes and go for a ride (this is now when everyone says "ooh err..."). I've made 23 bikes out of parts scavenged from the tip. They will be free to ride around town to see the exhibits, etc. Let me know what you favorite one was and a good name for it (and, no, they can't all be called Simey).

James, I can check my parts bin for a disused derailleur if you like. If I can find one you're welcome to it. What type of cable routing does yours use?
(this is a multiple choice question: "top pull" or "bottom pull").

hey cool, an ebay junkie :)... cheers for the links. I only replaced the rear cluster & chainrings 6 months
ago - I should have really done the conversion then. Will have to look a bit closer, although I'm leaning
away from a full single speed conversion just at the moment.
the only thing I haven't played with is the tension on the cable. But adjusting the limit screws didn't fix it,
but I didn't think cable tension would give me any more play.
steve if you had one that'd be awesome!! top pull (22/34/46 for what its worth).

Hey James, I'll have a hunt for you too mate. The next question is what diameter is the seat tube (so we can look for the appropriate clamp size)?
You can happily use a rear deraileur for a chain tensioner. I've also seen an uber-cool home-jobbie (called a royasm in our workshop) using a v-brake arm and a jockey wheel from a rear deraileur. simply and (cost)effective

hey cool. its ~1100mm.
PS: it was your shop telling me it would be a week & a hal before they could even look at it that prompted
this thread!!

Hehe. Around the freaking bay in a day meant around the workshop in 3 weeks. We're now savvy to at least look at stuff!
BTW, we need the diameter, not height. Sorry bro

oops, too many zeros (what's a zero between friends?)... 110mm (circumfrence). diameter is 30mm.

I just did a loop over the vic range that was very good ride - from buandik up the goat track past
milennium to mt thackeray and then on and down a managment track past the chimney pots to the
glenelg river road and back up the w side of the range on the harrop track (this was pretty sandy and
not much fun at the end of the day). great day, took about 8 hrs.
Anyone else done this one or other good loops in the gramps?
ps there's a map at

I always found the low altitude biking in the Grampians to be too sandy and slow - especially up near
Stapylton. Up high in the Vic Ranges could be fun - i drove that track the other day and its in suprising
good condition.

I was planning to do this loop over Christmas, but starting at Buandik, heading south along the Harrop track, then picking up the Vic Range Road and following it the length of the range to the Goat track, returning downhill to Buandik. I figgered that would get the slow sandy warm-up out of the way before a middle bit of serious climbing, followed by a joyous downhill.
Might leave the single-speed at home for that trip though...

I would recommend doing it the other way round - the goat track is rideable uphill, the other side isn't so
much.

I defer to the voice of wisdom and experience. D'you know roughly how far it was?

Don't know the name of the track, but it comes out on to the Glenelg River Road, just down from the Lions Head. If you do the loop clockwise, this is great. This is a Management Vehicle and walkers only track, so it's a bit naughty to ride it. I've done this loop twice, but last time was about 4 years ago. the descent onto Glenelg River road was very chopped up and loose, and basically unrideable. Going up this way, if the track is in the same condition, would be a walk.
There are 3 single track descent options off the main ridge in this area, but you will have to go and find them for yourself, for if I give directions for it on the web, then I am dooming it to massive errosion.

The Audax Alpine Classic (Bright / Tawonga / Buffalo area), was held recently and the weather was the kindest (fine & 23 degrees - unusual temperature for summer!), they have ever had for it.
How'd you go this year dalai / others?
