Maverick Sus: Anybody else sheared off a bolt?
6.4 miles walk home...Whew!
We're talking the two bolts that connect the link to the rest of the frame - conical head and conical bolt on each. My reaction on Day One was that these things looked kind of cheesey - to the extent I've tried to avoid assembly-dissasembly for fear of a tool stripping them. Today I got out of the saddle for a hill and felt the rear wheel wiggle. Stopped, and there it was: sheared that suckah right off. I'm pretty religious with the torque wrench - although it's not out of the question that the nut could have come loose. Only other possible way I can think of that I may have sinned is squirting a little ProLink chain lube into the things when they'd start to creak after immersion in water. (the instructions say to assemble dry....). I'm trying to think of a more robust replacement for these things. So far, I'm thinking to use two of the conical nuts on a rod of stronger material. Red LocTite one side, let it go off overnite, then torque the other in Blue.... Anybody? -- PeteCresswell |

Your repair is worth a try, but I suspect Maverick is already using high strength bolts. I use red loctite on the nuts on mine (also the two that hold the shock to the swingarm). Much as I love my Maverick-style Klein, I think when I get that next big "issue", I'm on my second frame, I may just have to move on. 'Course, with how much I've been riding it the last couple months, I'll be able to pass it on to my grandkids. :-P Shawn |

RE/
Bummer. Didn't you get it this year? Yes. Your repair is worth a try, but I suspect Maverick is already using high strength bolts. I use red loctite on the nuts on mine (also the two that hold the shock to the swingarm). They look conspicuously cheesey to me. "Low-Strength" would seem more descriptive. I'm not even sure whether the material is metal or some kind of plastic. One possibility, though, is that I had allowed the nut to come partially unscrewed - somehow transferring stress to a place it shouldn't have been. i.e. the strength when properly deployed is perfectly adequate...but the system is not very fault-tolerant when things come loose. I called Seven from the trail and they gave their condolences and volunteered to warranty the bolt and ship me 2 more overnite, so I guess "repair" is taken care of. I'm still, however, thinking in terms of a jury-rig kit in case it happens again. Walking's OK....but riding home is preferable. Much as I love my Maverick-style Klein, I think when I get that next big "issue", I'm on my second frame, I may just have to move on. 'Course, with how much I've been riding it the last couple months, I'll be able to pass it on to my grandkids. :-P Only thing that I was grumbling about was the supposed need to dissassemble/reassemble with fresh anti-sieze when it started creaking (which usually happened after immeresion or riding in heavy rain). Lately, though, I've come to realize that the creaking that called for the dissasembly was coming only from the area of those two bolts - and that squirting a little ProLink chain lube in there took care of it. OTOH, maybe the ProLink attacked the LocTite and precipitated the problem....gotta check the torque on the surving bolt. Since my contract exprired on Sept 30th, I've been riding mine a couple hours every day. The more I ride it, the more I think I'll never want anything else. If somebody ran over this thing tomorrow and their insurance sprang for a replacement, I'd just call Seven and tell them to build me one *exactly* like this one. Ran that past the local dealer and he said he hears the same thing on a regular basis - except from guys that really are ordering another frame... To be perfectly candid, Seven really ****ed me off while they were spec-ing/building this thing. I'd call up and ask them to make this longer, that shorter, or whatever...and they'd always reply to the effect of "No, we're sticking to our design". At some point, they passed me up the chain of command and a guy said something like: "Look, we've built a lot of bikes. We know what we're doing. Trust us.". I said "OK"...and it worked. In the end, I think they saved me from myself and my cockamamie ideas. Only improvements I can envision are a more elegant way to tension the chain (I'm running a internal-geared hub), maybe a better set of forks - or at least something with a lockout that's controllable from the handlebars, and a fewer cable stops (doesn't seem rational to me to have exposed cable down on the swing arms of an MTB). -- PeteCresswell |

Angry Man sheared his off last week and has a new swingarm on the way from trek/klein. That's twice now that he's broken his trek/klein in less than two years of owning it. He doesn't mind making "the machine" (aka trek) replace his bike frames because it costs them, though he would prefer a Maverick American eventually because he rides that suspension design so well. The bottom line? Companies like trek make disposable bikes to those who actually ride and ride often in various terrrain. Also, before any of the doubters start claiming that Angry Man is a hack and breaks bikes by thrashing down the trail, those who post here and have ridden with him can testify that he rides as smooth as butter.

RE/

That confirms my suspicion that if I kept hammering on this thing after the break that the rear swing arm would be damaged. I'm assuming that Angry Man also broke the bolt that connects to the swing arm.... Seems like the other bolt doesn't get as much stress. -- PeteCresswell |

JD One would think that if they take the design from Maverick and basically keep it exactly the same, one couldn't ruin it. Is it worth it to cut costs by using shoddy bolts? If you want to cut costs, use cheaper paint. Is it easier for them just to replace things everytime for free, rather than do it right the first time? I know you've probably hashed this out a million times in the NG. Where does Maverick produce their frames? -- o-o-o-o Ride-A-Lot o-o-o-o www.schnauzers.ws |

In my case it's a SevenCycles and I don't think they'd chince out on anything...it's just not their niche. I'm no engineer, but my take is that it's an engineering judgement thing. Whoever designs it has to make tradeoffs between weight, durability, installability, servicability in the field, fault tolerance in unexpected situations and cost. They came up with something that was light and seemed to do the job at hand. One could hope that it will evolve into something that is more fault-tolerant or at least could be replaced in the field....But I'm not holding my breath until that happens. -- PeteCresswell |

They were too far down in at the break and loctited. So, a new swinger is on the way. JD |

I think it's fantastic because it really shows what all of the cookie cutter bike companies like to do. They try to copy a good design, change a few minor details to make it look original or "innovative", and then cut corners where they shouldn't, making a disposable bike in the process. Only a fool would ignore these sad facts. I know you've probably hashed this out a million times in the NG. Yeah, so it only makes foolish people more the fool for ignoring it. Where does Maverick produce their frames? I would wager to guess that Reco Diver knows and a quick phone call would tell me. JD |

I'm getting a suspicion of how I managed to toast this thing and would like to hear if he made a similar move just before it failed. I don't know the name of the move, but in a tight space when you want to turn the bike; lean forward until the rear wheel is off the ground, then swing the bike around until it's pointing in the direction you want to go and let the rear wheel drop to the ground. When I visualize this done on a downhill surface, I see the forces trying to bend the frame in half when the rear wheel grabs the ground with the rider's downhill momentum on it - and trying to pop the head off of the bolt that connects the Mav link to the rear triangle. -- PeteCresswell |
