Description
Road crankset Sram Rival1 50T Xsync No Bb
The SRAM Rival® 1 crankset delivers consistent performance with every ride. Featuring the X-SYNC tooth profile from SRAM, the Rival 1 crankset is designed for total chain control. The thickness of each tooth is CNC-machined to perfectly match the inner and outer links of the chain. And with seven chainrings available, you can customize your gear range to suit your riding style.
Features:
- Forged aluminum with removable spider 38, 40, 42, 44, 46, 48, 50T X-SYNC? high square tooth design offers maximum chain control.
- Narrow, sharp tooth profile and rounded chamfer edges help manage a deflected chain.
- Recesses for cleaning inner chain links and rollers, 24 and 30 mm options
- Compatible with 130 mm frame spacing and 135 mm rear spacing.

- Featured technology(ies): X-SYNC?, GXP, BB30, Pressfit, PressFit30
Other:
- 130mm and 135mm compatible Technology: BB30: In addition to significant weight savings, this bottom bracket reduces Q-factor, clears the pegs, increases bearing durability and strengthens crank construction.
- GXP®: GXP's Gutter Seal design reduces friction and weight, improving feel and performance.
- PressFit: A variation of the GXP external crankset, PressFit reduces weight by up to 40 grams and makes installation easier by allowing you to press the bearing cups into the frame instead of screwing them in. It requires no modification to the length and diameter of the crank axle. Pressfit 30? This is a new design by SRAM. It's all the best of the BB30 and Press-Fit bottom brackets in one exciting package. This crankset is designed for 30mm axle cranksets.
- The main difference with the PressFit 30 is the way the bearings are mounted in the frame. The bearings are housed in nylon cups that are pressed into the bottom bracket of the frame. PressFit 30 has an integrated seal, pre-assembled in the cups, to extend the life of the bearings.
- Frames will need to have a 46mm inner diameter bottom bracket to accommodate this system.
- The PressFit 30 for road will require a 68mm wide bottom bracket, while the PressFit 30 for MTB will require a 73mm wide bottom bracket.
Advantage:
- Significant weight savings, reduced Q-factor, more space for pegs, greater bearing durability, stiffer and stronger crank construction, simple installation. Allows the use of larger diameter frame tubes, increasing frame rigidity.
Disadvantages:
- Still in research. X-SYNC the sram x-sync 1X chainrings offer the highest level of performance and durability.
- The edges of the high square SRAM X-SYNC teeth engage the chain earlier than traditional triangle-shaped teeth.
- The narrow, sharp tooth profile and rounded chamfer edges help manage a deflected chain. To provide the best possible performance in muddy conditions, X-SYNC chain rings were designed with mud clearing recesses for the chain links and inner rollers. Designed in Germany, the X-SYNC rings are an integral part of the SRAM 1X transmission.
