Very nice Greg - have you ridden it yet?
Took it for a spin this afternoon, duck & centre.
It certainly felt lite.
Climbed easier than the Reign (15.5kg) as to be expected.
But I think I will have to flip the stem as I found it hard to keep the front wheel on the ground on the very steep sections.
Flying down the Duck water bars I certainly spent more time in the air
Got to get used to having pro pedal for the first time, on, off, on, oops should be off!
I don't like the frailty of the forks, the carbon SID world cup's have a lot of movement, I turn the handle bar and 0.2 of a sec later the wheel turns
A learning curve I guess stepping down from my PIKE'S (I can move boulders with them)
I'm still keeping the 06 Reign but going to give her a paint job.
The best thing with the new bike is the chicks dig it
See you up the coast soon
Greg
PS: Rob, Thanks for sorting out the thumbnails.
I see there's a few (or is it only 2?) spacers there, you don't want to try moving some (1?) up top first?
As for the soggy fork... ahem... should have gone a lefty
Didn't think of that option!
Will let you know how it worked out.
Thanks
Didn't think it would be that easy to convert you to a Lefty!
Good on you for seeing the light Pikey...
I got one not being used with 100mm travel if you're innerested.
Hawkeye, (Rob & Junkie)
Firstly, These lefty Thingo's, can they take any skewer/hub?
Secondarily, what is the head set requirement (diameters) for fitting one of these oddities?
Thirdly, That is the travel of this lefty?
And most unimportantly, What are you selling this Lefty to me for provided it fits my new light weight beast? (PM me your $$)
(I need a different fork as I find the carbon SID world cup fork as flimsy as using two meat skewers as chop sticks )
Thanks
Greg
Call AMI now...
A Lefty will be much more stiffer than the SID and depending on which Lefty you get, probably lighter.
1st - nope, they require a Lefty specific hub, so a wheel rebuild (or new wheel will be required)
2nd - wider than what you have . Not sure on exact measurements, but you can get an adaptor they should sort it all out.
3rd - Hawkeye...
are readily available off fleaBay, although the one you will need for this fork will the more expensive of the two types with the lower fork crown/clamp integrated.
Travel is, I think, 100mm. It comes with rebound adjustment only and no lockout - it's an older model (Lefty Jake) but is in excellent condition. Previous owner was a very fussy racer and we've not used it, as I swapped it off the bike for the 130mm version I had lying around when setting it up for my son. All the wear parts (eg pin races, boots, air filters) are common to currently available versions so parts are not a problem. But the things are pretty well bomb-proof anyway.
Price I haven;t thought about, but I'll research and give you an indicator tonight.
The thing with Lefty's is that the springs are specific to rider weight - if you could let me know what you weigh it will tell me whether the fork is suitable.
I've found Lefty wheelsets are usually quite cheaply acquired, again on fleabay, if you are prepared to be a little patient. My last purchase was a set of 700c rims with roadie tyres, disc rotors, cassette, and XT rear hub for $127. Just watch the age of the wheelset as the earlier ones have four-bolt discs.
Publish it here!
By the way, how's all this potential additional $$ stacking up in the Department of 'Er Indoors?
a lefty is going to be my solution.
I don't plan on getting rid of my sexy Cobolt front wheel, although it can be easily converted to a 15mm axle so I might start investigating that option.
Thanks Anyway
You have spent too much time working for the Gov........what is the department of "Er Indoors" ?
That's one extremely sexy bike, pikey.
Replace ' with H and then watch an old skool episode of Minder......
@Pikey: No worries mate.
You do know you'll have to try one sooner or later, though.
I have seen somewhere a shot of a Cranky Brothers wheel on a Lefty, which I thought looked great, but I'd expect that the hub would not be cheap nor readily available secondhand (ie, at the right price).
This upgradeitis is a difficult malaise! In the last year I've treated my Jekyll to new fork, bar, stem, and shock, etc etc, and most recently with Rob's and CRC's assistance the transmission and brakes. The only things that're original are the frame, wheels and discs. In race trim with CrossMax wheels, it's only the frame and seatbag.
