Renthal: Renthal 1xr Ring 104/38t Brn

 

1XR 4-Arm 104BCD Chainring

Ultimate chain retention. All conditions.


The Renthal 1XR chainring tooth profiling ensures the highest level of chain retention, in all conditions.

Alternating 1.8 / 3.5mm width teeth interlock with the chain for ultimate security, with no loss of efficiency.

The reduced frontal profile of the 3.5mm wide teeth increases mud clearance for the inner chain plates and extends longevity.

Durability of the hard wearing 7075 T6 aluminium construction is maximised with a hard anodised surface treatment and mud evacuation grooves in the tooth bed.

Features:

  • Alternating 1.8 / 3.5mm width teeth. 
  • CNC machined 7075 T6 Aluminum.
  • Hard anodised surface finish
  • Mud grooves in the tooth bed
  • Ultra stiff I-Beam cross section
  • Mud clearance and wear-proof profiling
  • 104mm BCD.


Sizes: 30, 32, 34, 36 and 38t

Weight:

  • 30t 40g
  • 32t 42g

It took a while but the 1XR is superb quality and great value. If it lasts as long as the non-narrow/wide Renthal SR4 ring, it could easily be the number one choice for UK conditions.

DirtRag Dirt Rag Renthal 1XR

Ride Impression:

I set my 1XR ring up on a SRAM 1x11drivetrain with a 104 mm BCD Shimano crank. During an excessively muddy and snowy winter on the East Coast my Renthal ring saw plenty of thick muck and it never failed. Not once.

My rear derailleur could gunk up and the pulleys clog but the ring never seemed to notice it was muddy out. Obviously on dry trails as spring sprung the ring retained the chain perfectly.

I?ll also add that the vain side of me loves the gold color and styling of the ring.

Renthal has created a winner with its 1XR ring: it?s been working flawlessly.

If you?re running a 1x system with no chain retention device in any climate it?s a solid choice from a proven company.

And, being that Renthal is located in Bredbury, England, which is muddy about 75-percent of the year, it?s no surprise they know how to make a product that works in all conditions.

Although it?s been a while coming, Renthal?s entrance to the narrow/wide retaining chain ring market is damed impressive.

It?s nice when companies take a step back to make a genuinely great product.

There are three noticeable differences compared to other narrow/wide chainrings we?ve seen:

1. The machined channel of the narrow teeth extends further down, so mud holding on the shoulder won?t affect the chain, or build up enough to lift the chain and de-rail it.

2. In each tooth bed, Renthal has machined an angled clearing groove, so mud is purged down and out whilst the chain ring rotates.

3. The shape of the wide teeth have a profile that allows the ring to wear for longer before being replaced. When chainrings wear, the chain plates rub on the chainring tooth face as well as the rollers – this increases wear on both chain and chain ring, and adds friction. Renthal has machined the wide teeth so this doesn?t occur until the chainring is so worn that it will need replacing anyway.

The Renthal 1XR chain ring is an absolute no brainer. Highly recommended.
