evil E.13 bash ring question.

[dudski]

i got my evil bashring thing at the beginning of this season, never were the chainring bolts cranked on and now it is cracked in 2 places where the chain ring bolts go through. i do not think this is supposed to happen.

warranty?

o yes.......broken rear wheel and cracked crown on me fork and brakes slowly dieing......woooooooooo

[cycla4sh0]

did you over tighten those chain ring bolts?

[dudski]

some people are so smart, i feel like i have no brain at all.

[dudski]

any body know????


wheres dommm?

[Nelson]

Same with me.

[Lady Gravity]

apparently it's a common problem - i don't think lexan works as well as planned. i went through 2 sets of lexan pedals (atomlab) in short order - each pair was ridden about 3-4 rides before they either chipped or broke.

i'd say go for warranty and try and sell it

[PegCityThrasher]

Overtightening's a good way to do it. Or, if you weren't running the washers that'll do it too. Usually on the package it says the required torque to bolt it up. Something like 43in-lbs.

Edit: Even if they weren't "cranked" on, there's the chance you were running them over the max torque. I've been abusing mine for about 3 months with no problems at all. And I had mine milled down to a smaller diameter.

Picture this, you, me, a bubble bath, and a bottle of champagne.

[dudski]

not being cranked on AKA: not over tightened as in snugged up nicely.

3 months? i have been riding mine alot longer than you on yours.

lady g, i have heard badd things of those atomlab pedals and never thought of linking the two products together in strength
terms.(lexan breaking and such)

and Nelson.

i think i know why you broke yours, the chain ring bolts were too tight. :)

hmmm
if it's good champagne, i'll give you a 8 out of 10 - let me know your rate of success :P



oh and dudski, atomlab's not making those pedals anymore - go figure :rolleyes: but possibly e13 is improving each batch of bashguards - hard to say. i'd still go for warranty - ya never know

[Krusty Rider]

2 most common reasons for failure are: 1) not using the washers supplied. 2) using loctite or similar. The chemical in the loctite break down the lexan. If they don't cover it under warranty you can email e13 and they may offer a replacement at a substantially reduced price. This is from e13 direct. Talk to Jonas in warranty.

[dudski]

washers are being used, loctite was not used.

[skimtb1]

man, at least you can get your rings off, my chain ring bolts have seized, and my crank has seized, and the only way to get it off is to destroy the crank:P

dudski-

Ever get in touch with us here at the ofice about your bashguard? The torque rating for those bolts is only 43 inch lbs. At which point the female part of the chainring bolt (or the chainring nut) is supplying all the sheer strength that is needed for the unit to be bombproof. If the cracks are radiating from the bolt holes then this is the cause. It happens. Our bashguards are made of Lexan, Makralon, and a few other select ingredients to help them survive high frequency shocks - something any of those materials alone cannot absorb. So by overtorqing the chainring bolts the area around the bolt holes gets too compressed and will become more prone to cracking - the cracks don't have to happen immediately. Our No Fault replacement program offers the replacement of the exact bashguard for $15 USD plus shipping. Please feel free to get in touch with us directly at support@e13components.com or call us at 207.772.3132

Awesome to find out it's not a "defect". Seems like I'll be picking one up soon.:)

And Jonas, your signature is tempting...

[PegCityThrasher]

Jonas: Is it possible to get a replacement if I'm not the orginal owner? Mine's not cracked, but I was curious. Also, my bashring (when I got it with some used cranks) began life as a 44T size and now it's been milled down by a professional machinist to closer to a 39T. Can I get the size it's closest to?

Anyone who has problem with their e13 please PMed me and I will take care of everything.

who has a torque wrench in there tool box? nobody thats who...making parts that have to be so specifically tightened down is asking for trubbles...

[Jonas]

Why the hell am I working on a Saturday?

Duke - the equivilent of about 43 inch lbs is to just finger tighten the bolts while holding the short end of an "L" bend Allen wrench. We understand the issue for the mass market, and we're constantly looking for ways to improve our products.........but when properly installed we have had pro riders run our bashguards for three or more seasons without any issues.

PC Thrasher - we'd have no way of telling whether or not you truly are the original owner, so that's out of the equation - don't ask don't tell.........The fact that it's been milled down and therefore modified sort of negates the NF Replacement policy, sorry. But for future reference I can let you know what the outer diameters of the given bashguards are:
36T - 169 mm
40T - 185 mm
42T - 193 mm
44T - 201 mm

I can't really do the PM thing seeing how I've got four company email addresses and scan through ten different MTB Forum sites a couple times per day - things get a little overwhelming. We do our best to address every tech related need out there and with only so many hours in the day......... I guess it is an invitation....

Thanks for the help Dom........

Enjoy the weekend;)

Werd:fro:

[Uncle Duke]

I have never used your product so my comment wasnt aimed at you specifically...
My new Diablous crfanks also mention tightening w a torque wrench...I dont know anybody w one.

finger tight while holding the short end of a L bend allen key...I guess thats a good guide line.

[Jonas]

No offense taken, duke - you brought up a good point that every now and again we have to respond to. Most bike shops I know of don't use Torque wrenches....in fact, I know that a lot of bike shops don't like to hire mechanics how have gone to Barnett's b/c they feel that all the "torque crap" is too inefficient and time consuming. I went there myself and admit to still not using one, though. It takes a lot of years of wrenching to get a feel for what is required of certain nuts and bolts. And even then the human hand is still not a consistant match for the right tools.
I know you've never used our stuff - but if you ever run into anybody how does just pass on that little bit of info and the world will be a better place.
