last night I noticed my pedals and crank were "wobbling" side to side quite abit but as I took a closer look the pedals and crank seem fixed. The bottom part of the frame where the flex bone and bb sits is all loose! I think its called the main pin or bb-link but I have no idea how to fix this?.


Bike Model - GT ZASKAR 100 9R ELITE 2014

What type and model of bike?
A ( clear and well-lit) picture is worth a thousand words

I have edited my post...

Oh
its one of those wacky full suspension bikes where the Bottom Bracket itself is on a separate little linkage that moves around for Marketing Hype Reasons (BB shell not directly attached to the main triangle)

yeah, you don't fix it yourself
you take it back to the dealer and have them do it

Yer that's the type, its all come loose and my local servicing garage is busy for 2 weeks

While GT has used a paticularally unique suspension pivot design pretty much all rear suspensions are brand specific. Some brands do a better job at offering replacement parts for after market servicing. Some expect their bikes to have a limited lifespan and insted of having a business model with no long term support (meaning selling replacement parts for longer then the design is available on new bikes).


GT also has gone through various owners and distribution models in the past. I gave up trying to keep up with their stuff as it has become a bit player in the LBS market in general.


Good luck. Andy.
