Vlad’s Single Speed 29er, part 1

As the Spring is here after the long and brutal Winter, I’ve started to work on my own single speed 29er.  I am using Reynolds 853 butted/heat-treated and air-hardening steel tubing and my favorite Paragon rockers adjustable dropouts.  What is interesting about Reynolds 853 steel alloy is that strength of the steel is actually increases after cooling in air post welding.  I am using Reynolds’ bent downtube for better fork clearance.  The bent down tube allows me to use a shorter head tube as well.

To complicate things a bit, this build will be with shorter chainstays than my earlier frames.  The effective chainstays length will range between 410 – 422mm (16.1 – 16.6″), which is possible due to adjustable dropouts.  So, for my longer rides I will set the chainstays at the maximum length by moving the inserts of the dropouts, and for the rides with lots of switchbacks and climbing I will set the stays at the minimum length; or I will find a perfect spot between the range mentioned above.  The shortest chainstays that I rode on 29er were 17″, so I am interested to see how this bike will handle on the trail.  In addition, I am experimenting with Anvil’s bender by adding nice curves to the seatstays. 

The geometry of the bike is suspension corrected around Fox, 100mm fork.  It will have 44mm Paragon head tube and adjustable dropouts that allow chain tensioning to run a single speed drive train.

Thanks for checking in and enjoy the ride!
