COMPATIBILITY
For cranks MTB SRAM 8 bolts Direct Mount axle type: DUB
In the case of using the 3mm offset chainring with MTB Standard axle type cranks, the chain line will be 52mm (the hub spacing (O.L.D.) is 148mm)
In the case of using the 3mm offset chainring with MTB WIDE axle type cranks, the chain line will be 55mm (the hub spacing (O.L.D.) is 148mm)
Compatible with SRAM T-Type Transmission
We have designed universal teeth that work with other chains as well: SRAM chains - 11sp, 12sp Eagle, 12sp T-Type; Shimano chains - 11sp, 12sp HG+; KMC chains
INFORMATION
ALUGEAR is specialized in the production of high-quality bicycle components. We are one of the first who starts to produce 8-bolts MTB chainrings
Most have used a 3-bolts design for direct mount chainrings. But now the 8-bolts standard has come to be used for DUB MTB cranks and Power Meters more
We offer Оval and Round chainrings for 8-bolts cranks in several designs: AERO, Beach Ball, ELM, the large range tooth count of 26T-40T, and 8 color options
ALUGEAR chainrings are some of the lightest chainrings on the market. Using our experience and vigorous testing, we tweaked the arm design and strategically machined the chainrings so that only minimal sacrifices were made in impact strength in exchange for large gains in weight reduction
The chainrings are CNC machined from 7075 T6 aluminum and hard coat industrially anodized to provide protection from mechanical impacts, a good look, and an excellent tactile feel to each of the chainrings that lasts a long time
A unique tooth profile eliminates chain noise, reduces wear, and provides smooth operation on the entire system of all the most common combinations, such as 10, 11, and 12-speed drives. The Narrow Wide teeth guide the chain reliably
The tooth profile is specially designed for use with MTB chains
ALUGEAR chainrings are the best choice if you are looking for a technologically sound chainring with a unique design and low weight
RECOMMENDATIONS
Please use the titanium screw set M4x8mm to mount the chainring on the crank
We recommend the use of a clutch system rear derailleur for the best chain security
It is also a good idea to use a new chain with your new ALUGEAR chainring
It is recommended to use a well-lubricated chain on every ride
OPTIONS OF DIRECT MOUNT CRANKS
Most MTB cranksets have traditionally used a 3-bolts mounting, but the 8-bolts mounting has been used on the Quarq Power Meter cranks. Now some non-power meter SRAM MTB cranks use the 8-bolts mounting
