Getting a new fork on my '07 Tricross

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel".

On the Kona tech website there are customers with similar problems, with the JTS.

I have an older JTS with a Winwood Carbon fork, Vbrakes with Travel agent, no problems. What gives??

Haha its Alice Cooper, old time rocker. When they dressed like girls and some of them sounded like girls

Cool I hope you get your bike fixed. I have been wanting a tricross for a very loooong time!

so, I've just picked up my bike from the shop. To recap, I've upgraded to an Ultegra groupset and at the same time they added V-Brakes (with TAs) as per Specializeds recommentdation.

The breaks are alot less powerful and I find myself having to take massive handfulls of break to get any response. I'm not actually sure if I preferred the juddering to these. I'm waiting to see if the pads bed in a bit and the response improves.

I'll keep you updated.

Brake Shake, sounds better than fork shake, isn't uncommon with cheap CF forks. Have you all noticed that Specialized isn't replacing brakes. They're replacing the fork. A really high quality CF fork is expensive. Mfg's are notorious for using cheap parts to have product, not just a bicycle, fit into a certain price point.

On road bike CF forks the brake bolt goes into the fork crown. Most CF forks still use an aluminum crown, steerer and fork tips. On canti/V-brake CF forks, the mounting bosses are AL but there isn't any reinforcement on the actual fork legs.The stress of braking makes those fork legs shake and flex. Imagine what happens when you hit a few bumps. High end CF cross forks don't have that problem. They also cost $300 - $400 each. That's why you don't see them spec'd on a standard Tri Cross. On large frames with heavy riders, that cheap fork is a disaster waiting to happen.

Steel is real isn't just a saying old dinosaurs like to say just to be funny. If you had a steel fork on that bike there wouldn't be any flex at all. It would be heavier though. You make the call. Good luck

"Old time rocker" Hell, I bought his albums new when I was in high school. Those punks for Green Day are copying his eye makeup. There truly isn't anything new in the world.

The way to sort this without a warranty replacement is to get one of these https://www.fisheroutdoor.co.uk/publi...9h8gkkpoqf2ee2 (it actually points up despite the depiction in the photo), and a longer section of cable outer. Kills the judder instantly. It was explained to me that it has something to do with the length of cable from hanger to brake being too long and some sort of resonance. It's a design flaw of course. I have a Tricross Sport XL.

hmm, cool. Well, I got the call today that the fork came in, so I hope to pick up the bike tomorrow. If that doesn't do it, the piece you recommended is next. I'll have to find it through a US supplier though.

I guess any shop that is knowledgable about touring bikes would be the place to go before ordering from the UK and paying shipping etc. - I needed a longer bolt BTW as i have regular mudguards (or whatever you call them over there )bolted to the steerer on mine too (it's my commuter wheels - and Belfast is WET) and the steerer itself is quite thick too, but my LBS was able to hook me up with that with no worries.
Once I got that bit sorted out, I have to say, it's the best thing I've commuted on and I can leave my other bike for the fun things in life (for fun I ride this https://www.commencal.com/bike/mtb/20...b_meta_552.jpg)
Good Luck!

I've read elsewhere that the fix is as far as a set of mini-v brakes away. They do not require travel agents and allegedly work well. V-brakes are not meant for road levers, but mini-v brakes are.

see the fix here:

https://www.bikeforums.net/cyclocross-gravelbiking-recreational/315885-mini-review-oftektro-mini-v-brakes-my-solution-fork-judder.html

Perhaps install one of those brake braces that stiffen the brake bosses?

I got my bike back from the LBS yesterday and...



IT WORKED!!!!

The '06 S-works fork did the trick. Front braking is strong and judder free. The good news is that it's black, instead of red, so it doesn't look too awful on my green frame.

Valpo: glad to hear that your shudder problem is gone. was the fix only the fork? still sing the same brakes/pads/wheels?

i just got a custom build made using a (leftover) '06 sworks tricross frame/fork from my LBS. - I had been reading up on the tricross here on the forum, so prior to making the 'buy' decision I rode the bejeesus out of it and no shudder. So is this known to only happen on the non-S-Works tricross fork? My bike has different wheels and brakes than the production tricross models - maybe a different braking surface and brake make the difference. Is the s-works fork known to be different in design, geometry etc than te production fork?
anyway, glad mine didn't shudder, rode it a bunch today and no problem.

The only new hardware is the fork. I wouldn't mind getting some grippier pads, though. The fork is supposed to be a higher-quality carbon fiber weave. It's a smoother ride too. My bike is finally just the way I want it. I'm pretty psyched!

yeah, it took about a month for the s-works fork to come in and be installed. Granted, they were on a 3-week backorder, and it took 2 days to ship, so all in all, the LBS did all they could...

I've been running my Tricross now with toed-in brakes for about four weeks now and it's much improved. I originally misunderstood the idea of toe-ing them in: I started with the trailling section of the pad touching down first. This worked for a while until they wore down a bit and then promptly became unusable. Changing the toe-in so the leading section of pad touched down first has almost cleared the problem.

It seems from this experience that the excessive play on the brake mounting post is a significant factor. My brakes show noticeable yaw along the axis of the mounting bolt when manipulating them by hand. This means that the angle between the pad and the rim changes as the brake is applied, effectively rotating the pads forward (ie: the right pad is rotated in a clockwise rotation when seen from above). By toe-ing the brakes in on their leading edge, the angle between pad and rim increases in size, thereby reducing the effective braking surface. This eliminates the judder which is caused by a positive feedback loop.

The lesson here? Specialized should specify brakes which are a good fit for the mounting bolt.

I also did something which will probably make you think I'm crazy, but I cleaned the rims using clear petroleum jelly, and wasn't too dilligent about completely cleaning it off. There's probably still an invisible residue on the rims which lowers the level of bite when I put on the brakes - and yes, they do still stop the bike!

My Sport is in with the LBS (and Spesh dealer) at the minute, as I decided to let them fix it properly (and in warranty) even though my workaround of the crown-attached cable hanger did a good job - Specialized in the UK are replacing the canti with a v-brake & TA setup as the solution. The LBS's first attempt at a diagnosis was that I must have a loose headset - I wish they wouldn't assume that people were idiots every time they pick up the phone...
