I’ve a Flux DW and I built it up with no intention to racing or speed/efficiency…more for just plain fun and a bit of enduro/marathon. When think racing as well, by today standards (CF frames etc) the Flux is not that light…came up bang on 6.0lb for just the frame.
For mine it was wide bars, short stem, dropper seatpost and Reba U-Turns. Was tempted to stick a pair of Rev U-turns (100-130mm) but the Reba suit it perfectly…didn’t feel it needed anymore travel at the front.
It’s a great bike. Fast and stable on the downs particularly given the low BB, great on the Surrey Hill trails and climbs very well. It’s not perfect imo…the travel is very plush but I find it goes through it quickly and I bottom out quite a bit if I find more technical descents or trails where you’re getting off the ground. You could of course up the shock pressure which I have tried but the plushness goes and so for the vast majority of a ride you losing that benefit…better to have the odd bottom out imo.
Worth the money over say an Anthem X or Trek EX8? Well I’ve had an EX8 and had other FS frames (Ellsworth Truth, SC Superlight) and personally I’d say no. Lovely frame, great quality and good support and that’s worth something plus the discounts around are good.
