    Carbon Fibre Down Tube Protectors, For Reign,Trance,Glory,Anthem, anybody use one?

    Im just about to pull the trigger on a Down Tube custom carbon fibre rock guard from 'Rock Guardz'

    Rockguardz - Real Carbon Fibre MTB Rock Protectors

    This looks like a great little company, has anybody ordered from them?

    Ive got a 2012 Reign, and they have a very flat bottom on the down tube and the guard that this company makes looks great for the job, they are custom built to fit the Reign, Trance and Anthem.

    After looking at them on their website im pretty much sold, they sell for UK 32 pounds or about $50 AUS, which i dont think is too bad..

    So has anybody seen or got one or had dealing with this company?

    Cheers nand have a great christmas and safe holidays...

    I'd make one in Aramid.
    Carbon is not the material of choice for that application.

    LOL Magura, stop throwing a spanner in the works

    Id rather just order one, i dont have any Arimid lying around what ever the hell that is lol

    Why do you say carbon fibre is not the material of choice for this application?
    They seen to have made a business out of it, they make them for a hell of a lot of different brands, and they look pretty sweet.

    Are you just being objectionable for the sake of it Magura lol

    Cause Aramid (Kevlar if you buy the DuPont version), is what is needed for the application. Aramid is fairly common, so is epoxy, so unless you just can't be bothered to make one yourself, that's the way to go.

    For this application, I'd guesstimate Aramid in the right config, would offer several times the protection of carbon.

    Carbon fiber shatters. Aramid is tougher when it comes to trauma. Try cutting a kevlar sheet with a pair of scissors and it becomes a tangled mess.

    I guess they've made it a successful business because you'll have to keep replacing carbon protectors at a faster rate than kevlar ones.

    Magura, you need a lesson on making crap parts so you get return customers.

    Ive just read a few reviews from guys that have used and abused these guards and they are nothing but great, no talk of them shattering, isnt there different ways and methods that carbon fibre can we woven or put together, im willing to bet that these guys are not making a product that shatters on impact, they have been in business for a while and their products have good reviews.
    I agree with Magura that there might be better impact absorbing materials around but these look light and clean.
    Im leading to putting an order in for one and if it turns out to be a lemon i will have no hesitation reporting back here about it.

    I was making a generalization of CF parts vs aramid parts. It's hard to shatter the downtube protectors because of the "backing" that it is protecting.

    However, if you have a small strip of CF in your hands, try snapping one vs a Kevlar strip. (gloves and eye protection required). Makes a good illustration of the differences.

    See I try real hard to keep customers away, at least bike part customers

    I'd have to agree though. Kevlar protectors would be a bad business model, as you'd only sell one.
    The only thing that could save it, would be that they don't fit when people replaces their bike.

    The Kevlar - carbon layups I experimented with a while back, were extremely tough. I managed to break chips of the square edge concrete block I used for the test.

    Maybe we should go in the bike composite business?

    I have one on my carbon trance, I wouldn't say the fitment is excellent, but its does stay put. By that, i mean it moves around a tad, no biggie. I tried to take it off to clean it at one stage and the side cracked a little so I left alone. It's strong but fragile. Once its on, leave it on I guess! But it does a great job in protection.

    Had my time again, i think I'd simple wrap tyre tubing around the lower frame as an a alternative.

    I recently ordered one for my 2013 Glory. It took a couple weeks to make it here to the states. It's really a tight squeeze to get it to fit, but it sure won't fall off! I put some protective tape on the frame, otherwise, you'd trash the frame's finish trying to install the guard. I mean, I was really having to force that thing apart to get it on. It's pretty f'n strong. While I'm sure it will work to protect the frame to some extent, I think there's room for improvement in the design. It's not going to shatter, and anything that would cause that kind of damage would kill the frame, anyway.
    May the air be filled with tires!

    I have one on my X4 mate. Does the job as it has some chips in it now since the summer so I'd rather have that dented than the frame. Fits a treat and made to high standard

    I got the same one as above in the mail a few weeks ago and im very impressed, it fits like a glove, is rock hard, well made and im going to go against a few of the doubters and say theres no way you could ding your downtube through one of these, its just too hard, its the best $39 ive spent on my reign, id suggest to anybody to buy one of these if your concerned about dings to you downtube, its a great design and im very happy.

    Yours might have been a bit of a tight fit, mine fit like a dream, nice and tight but easy to get on and off, no paint damage at all, no need for zip ties or anything to hold it on, no wonder this guy sells thousands a year, he makes a good product imo.
    Im looking forward to seeing how its holding up in a few years..

    Most bikes don't need something that beefy. For the XTC and Anthems I'd just recommend going with 3M tape, ie helicopter tape. Lizard skins also makes a tape in various colors that works well. I've used this kind of stuff for years on my carbon bikes and never had an issue. Plus you can put it anywhere and you get a ton of it for less than the other $39 piece.

    I wouldnt call it beefy silentfoe, its only about1-2mm thick, its just very hard once its on, very light and looks nice and clean on a bike, i think its money well spent, but i understand where your coming from.

    Mate, i would if i could but i use the girls computer and i dont think ive ever posted a pic, im pretty computer illiterate, but its pretty much the same as the one on the trance above but they have little rockguardz yellow logos on the side of them now.
    I have seen them on your white 2011 reign 2, they look slick and really professional and clean.
    The guy that makes them i have in the link in my original post is a top seller on ebay, he posts fast and has great feedback, so i recommend him for sure.
    There are some on reigns in the giant section on this forum, i think in the blog of 'show us your reign, if you buy one i think you will be very happy, cheers
