I’m also looking for an x-firm spring/ride kit for 2010 Minute 29er 120mm…I phoned manitou USA and their tech support guy said the parts diagram for the 29er minute forks in the 2009 service manual is wrong. He said the parts listed under the 29er fork are for the 26er. He gave me part number 141-26744-K003. I had already ordered part number 83-3177 as per the manual and the above post but he said that part is for the 26″ model. I phoned hotlines and TF tuned with the part number and they said it didn’t show up on their system at all and it doesn’t come up in any web searches. Manitou USA have them in stock but only sell to dealers. I’m confused? Can anyone shed any light on this?
