19.5kg mullet.

20.2kg grip setup.

Custom ZEN Carbon Bike 27.5 rear wheel.

Custom ZEN Carbon Bike rear 27.5 wheel came in the mail today! My Amflow is now a mullet setup (IE: Party in the back with a 27.5 wheel and 29″ front wheel). I have 4 setups now, original Amflow carbon wheels 29″ front and back, ZEN Carbon Bike 27.5 rear with original Amflow 29″ front or DT Swiss 1200 Spline front (DT Swiss 180 hubs) with Tufo tyres + ZEN 27.5 rear, or DT Swiss with XC tyres front and rear.

I’ve left the chip in 29, for now as a lot of you have suggested that it works well (and I’m only 60kg’s). Can’t wait to hit the trails IN THE NEW YEAR! HNY ALL!

Sorry about the camera angle. Will get it right next time!

A little trick I’ve been doing for years; I use a quick release skewer to help keep the lockring removal tool in place. Always works a treat.

36T ring.

More clearance between chain and chainstay now with the bigger ring.

I’m finding that I’m spinning out on the Amflow on the flat stuff so I’ve upgraded to a 36T chainring.

I got the Amflow chainring removal tool by buying a new spider from the Amflow web site (it came with the tool, lockring and chainring bolts). The chainring itself is a SRAM 36T T-Type so a direct swap. Last picture shows chain clearance from the chainstay protector with the bike unloaded (size Medium) and in smallest rear cog. Final step was to open the Avinox app and select 36T. Nice and easy!

The AMFLOW is a beast on tarmac too!

Much thanks to Jet Cycles.

I picked up this frame for free recently, and thought I’d try to build something up using only parts from my parts bin. In the end the only thing I had to buy to make the build work was the seatpost as it’s some weird Mongoose size. The bike rides really well! I have no intentions of keeping it though, got way too many bikes, so this one’s going straight to FB Marketplace.

Finally caved and decided to remove the 10-Speed Microshift and other AliExpress parts and source more period correct parts for the bike, namely an XT groupset, half of which I stole off my Cannondale Super V (which I’ll upgrade to XTR over time), and the rest I sourced on eBay bit by bit.

Really happy with how it’s turned out! Shifting is so much better now, it all just looks and feels so much more right (to me!).
