Yes, as it also supports the weight of the rider and the front end will dive excessively or bottom out if overloaded.Here's K2's recommendations for the Crosslink from the manual:Rider Weight (lbs) Spring Rateup to 140 175130-170 200160-200 200 (Standard as shipped I believe)190-230 225over 230 250Col.
They diagnosed my chain falling off issue. Looks like the middle chainring is bent, which is why, when I get on it on the middle chain ring the chain pops right off. Small and large chainrings seem to be fine though. Any suggestions? Maybe someone has, or can direct me towards, an appropriate used crankset.

Maybe someone has, or can direct me towards, an appropriate used crankset.Why didn't they just replace the chain ring?Or DIY! unless the crank is damaged as well?I've even taken a bent alu granny ring off, hammered it flat and returned it with no issues.If replacing it, you just need to know the No of teeth (although you can go up or down a couple if you want) and the BCD.http://sheldonbrown.com/gloss_bo-z.html#bcdAlso, check that none of the chain ring teeth or rear cassette teeth are badly "shark toothed" i.e. worn out, as this will also cause a slipping chain and finally make sure that the derailleurs are set up correctly, check out Sheldon or Shimano for instructions on this as well.Now, enough with the excuses! get it sorted and get out there and ride it! <GRIN>Col.
Hi thereMy tuppence worthBin the current cranks get second had good brand cranks 4 or 5arm type you need stiffer set up than you have,Think about BB might be about knackered anyway square drive or ISIS but must be rebuildable.Two rings at front 46t if it has clearance 44 was standard34t middle ring, you are big lad you won't need granny ring its quicker to push at low speed and less balancing get good quality NEW ringsPedals DMR V8 good reviews rebuildable Above all strength is what you need in your drive train Hope this helps youPetePS 9degrees C here
Hi thereI'll give you a few wee tips do lots of research before you buy anything online MBR good for reviews weight weanies etc and from fellow cyclists in your area and Local Bike Shops I would not pay more than half new price for used partsWhich can be picked up online (the bay/pink bike/ Craigslist etc) look out for New Old Stock, next years models will be hitting shops about now bargains to be had.Ask around and take your time Ask fellow bikers if you can try out their set ups or borrow their bikesPete
