“2X - 104/64BCD” MTB - 29/X0
Top weight, unmatched transmission range (4 pairs), up to
6 shifting sections (“SPS”). The optmal choice for low and
medium range 2X-transmissions, f.e. XM557-2X.
TRANSMISSION VARIETY
4 transmission sets: For every requirement the right answer:
- Regular : 34/20T - 36/22T - 38/24T - 40/26T
- “20T/64BCD” ring needs “special 11 mm bolts”!
“SPS” - 9X / 10X / 11X
“Smart Performance Shifting” (“SPS”) integrates the maximum
number of shifting sections into B.O.R’s 2X outboard rings, additionally
optimising them for electric gearing systems. DI2-ready.
Maximum compatibility for 9X, 10X, 11X systems. 11-speed usage can
require “shims” to adjust ring spacing (depending on crank).
DESIGN & WEIGHT REDUCTION
Simple and flat design are the basis of our light weight
concept. Weight per pair starts at 55,0 gram - 34/20 teeth
(42,0 + 12,5 grams).
MAXIMUM DURATION
“Double Surface Treatment”: High strength alloy, additional
surface compression, chemical brightning, anodisation make
for optimized tribulogy and secure long lasting performance!
“DIRECT BOLT”
“Direct Bolt” allows for quick change of the outboard chainring
by bolting directy into the ring: M10x0,75. (Like SRAM XX).
“Conversion 2X for 3X”
Also suited for converting a 3X crank into a 2X crank, provided
sufficient space between rings and chainstay is secured.
(F.e. SRAM X0, Race Face 3x-104/64, Shimano XT-104/64 etc.)
