I did a long spreadsheet to build mine and the missus Blur LTc’s
Outcome was for an initial investment for her the Basic build kit was the best option with a fork upgrade then upgrade as we went – we did a swap out on the wheels with the LBS. 18 months on and there isn’t much of the existing build left.
I did mine as a full custom build but using complete bargain parts (the lbs has most of what I wanted available at the right price) the build was at a price I won’t discuss but was very good.
When we came to the missus and her Tallboy as it was out first trip into 29 the build made sense again. She ended up going up a level or so and getting the X01 Fox Kashima build. We had no 29r wheels or fork just a drive train. The build price was better than we could have sourced from parts at the time. Couple that with it’s nice to have a new bike with new kit that works well and is all compatible.
Long and short if your moving to 650b then you probably can’t reuse wheels and forks – forks are certainly at a better price over here in Oz via SC than the other importer.
The one thing we have going for us down here is the Au$ is worth something where as the pound is still crap!
My only problem with the build kits is the lack of a SRAM option at the x9 level.
