-LEAK- Shimano's Newest Entry Level Groupsets For Road and Mountain Bikes REVEALED

One: BRAND NEW Entry-Level Shimano Groupset for Road Bikes — Claris. Two: A Revamped Shimano Deore Groupset for Mountain Bikes

Recently, Shimano revealed the details of these groups. Check it out!


When referring to Shimano parts, it's easy to come to the conclusion that "Everything Just Works." These statements are becoming more true for the lowest level of Shimano groupsets, as the technology trickles down from the high-end parts.

The Claris is replacing the 2300 components, and as a beginner-oriented groupset, it will have low gears. Choose between a 50/34 compact and 50/39/30 triple chainset options, and select between the sprocket clusters of 11-28, 11-30, and 11-32.




What do entry-level riders need in a groupset? Shimano knows. They focused their efforts on improving the fluidity between the chain, chainrings, and front derailleur. This makes the front shifting mechanism work much more smoothly, further extending Shimano's philosophy of integration to it's cheapest groupset.








The rear derailleur comes in two different versions to accomodate the different sprocket clusters. 







In order to keep the costs down, Shimano kept a clunkier look to it's braking system, as well as keeping one piece moulded brake pads rather than separate ones like their high-end dual-pivot brakes.










Since the Claris will be Shimano's cheapest groupset, and yet will contain many of the great features of the higher end componentry, it can very easily be used to dress up your current bike. It has levers with built in shifters (for flat bar bikes) as well as individual levers and shifters. The lever units now use the same design as the rest of the Shimano groups, making it much simpler to shift gears from the drops.




Moving to mountain bikes, Shimano has redesigned its Deore group, once again improving the technology to make it more like the more expensive XTR, Deore XT and SLX levels.




The most notable of the improvements is the upgrade to a Shadow RD+ rear derailleur, and new gearing options for larger wheeled mountain bikes. The internal clutch is widely considered to be the best way to control a flapping chain.



The new Shimano Deore offers chainsets with smaller rings to compensate for the gear increase caused by the larger wheels of 27.5in and 29er bikes. The new chainset options are 40/30/22, 40/28, 38/26 and 38/24, plus the 42/32/24 that was the only previous Deore offering.

"More Options" is a good way to describe this group, as there will also be a version for flat bar bikes with larger triples, slightly smaller sprockets and a conventional rear derailleur. Shimano is also introducing a Deore version of its Ice technology brake rotor which sandwiches an aluminium sheet between steel braking surfaces for better heat dissipation.
