Hi,

Is any one running the Straitline silent guide?

Some real world feedback would be great.

I've got a P30 gamut which works well but I really like the look of the Straitline and the promise of silence!

Cheers.

Anyone using this?

I'm wanting a full bash style chain guide so it's this or the E13. The E13 is harder to clean and the rollers don't tend to like british winters so the Straitline seems to be a good choice. I have never seen anyone with one on their bike mind, local riders, races or WC's for that matter.

Anyone?

I'll hopefully have one installed on my new frame by this weekend... Mine's still sitting in the box.

They look neat but at Ft William world cup I saw 3 riders with them and they all had wasted race runs caused by this thing cocking up and failing.
Shame really as I loved the idea of it.

Can you be more specific on what caused the failure? I'm not sure what you mean by "cocking up".

I installed one on our Banshee Legend recently and it was very promising on it's first day out. Granted by that I mean that I rode it in the parking lot and took a picture of it in front of a white wall. The chain stayed on fine throughout the entire photo shoot. :rolleyes:

Seriously though there isn't much to go wrong with it other than outside forces that would cause other chainguides to fail as well. It was nice and quiet and showed no signs of failure or faulty operation during the multiple runs that I've had on it. I didn't have any extremely hard impacts to the bashring that day but it held up to the few small impacts and rock scrapes just fine.

really? they had them go wrong. i was a pessimist before but the straitline owner talked me into trying one for a while. I never had it go wrong. Basically just never had a problem and didn't really think about it.

That being said, it's the same price as the e13 srs and i just like the finish on the e13 better so i doubt i'd buy the straitline again

I saw that on Freecaster (at least one of the failures anyway). I was surprised because I thought it would be the one with the least problems.

I've been using one for a few weeks now and I absolutely love it. It has been by far THE simplest and cleanest guide I've ever installed. With the 13" BB on my new rig, I am very glad that bashguard is thickass 7000 series aluminum - it gets used. The backplate is really thick machined aluminum too and is really stiff. In the event the chain tries to jump off or gets yanked to the inside, I don't think this backplate will flex at all to allow the chain between the chainring and backplate (I have had that problem in the past in circumstances where the chain would droop into the swingarm yoke from hub drag or something, or if the derailleur got tagged and let the chain between the cassette and spokes and I'd try to give a pedal stroke on accident - both situations resulted in totally jammed up chainguides due to flexing backplates on Gamut guides and E13's).

I'm curious what was failing at the Ft. William WC and if it was attributable to improper setup. They seem pretty idiot-proof.

Dead silent, extremely well built, no drag, no moving parts. I'll be buying more of these when the need comes.

Another nice thing - if you call Straitline directly and ask for a 2nd-gen Saint specific guide they have a bashgaurd that is cut specifically for them. No grinding or filing required.

Our team (6 riders) have been using them all summer long on our Morewood Makulu. We have been racing the entire Quebec Cup, Canada Cup, Nationals, 1 week of riding in Whistler, multiple days of riding in Bromont and Mont-Ste-Anne. Our top rider raced Champery, Val Disole, and Windham World Cup as well. I am the team mechanic and all in all we experience no problem what so ever, no drop chains, no bent bash guard, nothing. Super easy to work on, super silent, and very easy to clean as well. Definitely a big thumbs up! I was skeptical at first, coming from super reliable GAMUT P30's, but I must say that I am pretty sold to them now. I just put one on my Yeti 575 for XC/AM riding, and I'm pretty stoked as it is very silent.

i used one all season on my 951. had to slightly grind down the top of the boomerang for it to fit but didnt drop a chain all year. the bottom guider is a lot stronger than the E13 roller which i had to replace a couple times from it smashing off before i got the straitline guide.

Ive been using it for the whole season now. Best Chain Device ever. Rode it in Mud, Dust, Rocks, whatever. Never had a problem with it. The bash ring is strong and has no problem taking hits on my 13.7 inch bb. The backplate and sliders are also strong, got some direct hits into it and it only turned. It has been the busiest season in the last few years for me and one that tested my chain device the most. Seriously Recomended.



Also 32-36 silent guide with bash weigths almost THE SAME as lg1+ with taco. Look at sicklines weights. Only 3g differance.

Plus, they look cool.

It took me about 9 days riding before I smashed the taco off my bike. Once the Taco was gone, seems I never clipped my rings... I guess knowing it wasn't there for protection made me less of a hack.

NOT BLOODY LIKELY!

X2!

I have had it on my Makulu and Kalula. Never has failed me from Whistler to Windham.

I have been using one this season on a Yeti 303R DH and it's a very solid guide. The chain rolls smoothly on the guides, it's quiet no matter how muddy and grimy it gets, and it's a piece of cake to maintain.

Two things to keep in mind:

1) If you are going to use it with Saint cranks make sure you purchase the correct model (Saint specific). The bashguard is machined a little different to allow for the slightly thicker spider on those cranks. If you use the standard bashguard on Saint cranks, the chain can get stuck between the chainring and the bashguard.

2) Alignment of the top roller is crucial. This is particularly important for frames with adjustable geometry. I mounted the chainguide with my frame set at 64.5 degree headangle and when I changed the geometry to 64 degree headangle I started having issues with the chain skippin a tooth on the chainring occasionally. I rotated the chainguide back a little so the top guide would hold the chain tighter and the problem went away.
