My first cyclocross bike (Cresta)(18 posts)

My first cyclocross bike (Cresta)Jenseman
Oct 12, 2002 2:57 AM
Hi,

I´m a German biker, who just built his first cyclocross bike. I used some old (campagnolo wheelset and shifters, Dura Ace crankset) and some new parts (WCS stem, Handlebar, Daytona derailleur, Schwalbe CX Tires). Now I need to change the chainrings to 38/48. I already ordered some TA chainrings. Only rode the bike two times off-road and it´s absolute fun even on downhills. I´m used to my full suspension MTB, but this is really fun!
What do you think of my bike?

The frame is from Italy, but probably made in Taiwan.

Greetings
Jens
Nice ride...Mitch2

The frame almost looks like my first cross bike w/c was a Trek X01. What rims and tires are you using?
Oops! Disregard the question above..Mitch2

I did not see the you posted the wheels & Tires.LOL Still too early here in Southern California and I just started sipping my java.
Very nice.www-mtnpedaler-com

I hung my parts on a from USA, but defintely made in Taiwan frame this year. But it doesn't look as nice as yours. Going to race it? Paul
Very nice.Jenseman

Thanks Paul.

I would like to race it, but there are not to many occasions here in Germany. But first I´ll have to improve my riding technique this winter,

I take it there are not to many cross races in Germany? Racing is a great way to improve your technique. Go for it. It will be the hardest thing you have ever done. But as soon as you get your breath back you'll have a ear to ear grin. Paul

Excellent rig, and very nicely done. I noticed the top-routed front shifter cable--what are you using for the front derailleur?

The front derailleur is a Shimano 105 down pull. There is a cable routing mechanism with al small roll below the the derailleur to make it usable. It´s not the best solution, bur it works. I can take a picture of it , if you like.

Actually, that's what I had to do on a Bianchi Axis, when I found I had to use a 105 triple front derailleur in place of the stock LX in order to run a triple crankset. It does work quite well.

What is this device you speak of, where can I find one, and for how much? I've got an Axis, that I was thinking of converting to a triple after my last race of the season.

I'm running the 105 sti levers, LX front der., and race face cranks w/ 46/34 rings, and would add the 24 ring back on later for trail riding this winter.

Thanks
This was what I didThe Walrus

I couldn't find anything commercially available that did what I needed, so I wound up cobbling together a gizmo from a Travel Agent pulley and an E-clamp, from the QBP catalogue (on the derailleur accessories page). It made for a neat, sturdy and smooth arrangement. For best results, rotate the assembly on the seat tube about 10 degrees counterclockwise, so that the cable run coming off the pulley approximates the path it would follow from a bottom bracket shell cable guide.

I'm guessing the parts totaled around $30, which sounds pretty steep perhaps, but this has worked flawlessly for over a year now.

Thanks,

That looks like a nice clean setup.

So, just so I have it straight in my head, the reason you need to go with this setup is that the STI levers don't pull the correct amount of cable to operate an LX front der. as a triple. Therefore you have to run a 105 triple front der. which only comes in bottom pull model, hence the need for the pulley to reverse the direction of the cable pull.

Whew, did I get all that right?

At any rate, not sure what I'll do at this point, I've got an odd combo at the moment with the race face crank and 107mm UN72 bottom bracket. I think the chainline would be perfect for a triple, but to get it corrected for the double setup I'm running I would need to go with a 102mm BB.

That is why I'm thinking of running the triple setup, but probably wouldn't be worth if I need to do get a new 105 triple front der. and a "Patended Walrus Doohickey". I'd be better off keeping the double setup and running with a 102mm BB, although those seem to be harder to come by in square taper at reasonable prices these days.

Thanks for sharing the pics though.
You got it right...The Walrus

After trying everything I could think of to get the 105/LX setup to work, I resigned myself to this solution. I was lucky because it turned out the only thing I needed to buy was the E-clamp; my parts stash supplied the rest. (This is why I NEVER throw anything away...)
OK.....Thanks again (nm)TWD

The Alan Bikes had that set up stock....atpjunkie
Oct 17, 2002 6:25 PM
....in the 90's. My Ridley actually has a threaded hole for the pulley. Alan cycles probably still makes that device. I've run an XTR front der. / top pull with Ultegra STI's and a triple with no problem at all. I'd still be running it but I switched to bar ends (I'm a phreak) so maybe the LX doesn't work top pull but XTR does...maybe XT?
I dunno...The Walrus

The 105 STI (triple) levers and the LX derailleur were both 8-sp, so that might have been part of the issue (--and yet, the RSX triple STI on my old touring beast worked just fine with LX...strange). Whatever it was, nothing worked, not even the cable pull "booster" I threw in there.

Hey, atpjunkie--I just realized I missed that midnight ride again back in August. How was it?

wacky as usual. people dresssed all crazy with wacky light set ups, some with booze in the water bottles, ya know the gig. One of the best "fun" rides around. Cool thing is I live close enough that I can ride to the start and home from the finish (with Balboa Park Trails) to and fro'. we have a new look, Mormon CX team. Cross Bikes with short sleeve button ups and ties, works great for the pub crawls as well. (That was last week with a ferry ride to Coronado). yes we in San Diego do have 2 wheeled pub crawls and most of the girls have more tatoos than the men. Uptown is a very strange land. If you ever come down I'll take ya on some of my tracks. It's starting to feel like Autumn.
PLEASE NOTE: such behavior is not condoned nor suggested by me, I'm just reporting the facts ;)
