Spy shots: Shimanos answer to XX1?

Most recently in the wide drivetrain news was the fact that SRAM had released X01, a trickle down group from their top tier elevel speed drive train. What was puzzling about this new groupset was the fact that it weighed just 40-60g more than XX1 and retained both similar features and the blindingly high pricetag! SRAMs argument was at the original equipment level X01 worked out far cheaper meaning complete bikes would be both eleven speed and fairly affordable. Where however does that leave the riders who, like me, buy a frame and either build it up with a custom specification or alternatively use many parts from their old bike to keep the cost down. The rumours are still circulating about XX9 and how soon we will see it being released however on Jared Graves' winning Yeti from the EWS at Crankworx Whistler something exciting was being tested. Although Graves appears to be using a standard 10 speed XTR mech (likely long cage) it's coupled up to what appears to be a 11-40/42 cassette (standard freehub compatible), providing similar ratios to XX1 but without having to replace the rest of the drivetrain! Even if cassette prices were similar to the prices SRAM are charging merely by making the system compatible with the existing shifting gear brings the price down massively. RRP for the existing XTR cassette is £209.99 (cheapest XX1 ~ £245 (Bike-discount.de) so even if it went up by another £50 it would still be undercutting SRAM massively! Some healthy competition can only be a good thing for the wide range cassette market although it'll be some time yet before we can purchase the Shimano offering. Although the lower 7 cogs appear to be of the standard XTR variety the upper 3 seem a very rough prototype - no doubt Shimano will wish to refine these further prior to releasing more information.

Trickle down tech: XX1

Recently, SRAM released a revolutionary new groupset: XX1. This drivetrain was a brand new concept, one by eleven speed, with a huge ranged 10-42 tooth cassette matching up to a range of chainring sizes from 28tooth all the way up to 38. This groupset changed trail riding completely, allowing a single ring set up that had the range to cover most terrain, whilst the need for a chain guide (thanks to the alternate profiled teeth) being nullified.

Although fantastic, the price of XX1 was hugely inhibiting, with prices of around £1000 for the complete groupset - more than many riders spend on their bikes. The latest on trickle down technology is that SRAM are slated to release XX0 in the spring of next year and XX9 later on in the autumn. If this new tech does reach an accessible price point where does that leave Shimano? Are they planning to launch 11 speed, pioneer DI2 mountain shifting or in fact follow in SRAM footsteps? The trend of previous releases would suggest Shimano will showcase a product similar to XX1, however perhaps more refined. At this stage it is mostly speculation, but one thing no one can deny - the future is bright for trail and all mountain riding!

Long term product review: Shimano Zee mech/shifter

Shimano's latest groupset, Zee, is aimed at the gravity/enduro market bringing an affordable, efficient and hard wearing 1x10speed drivetrain to the masses. Having written off both mechs and mech hangers using a widespread cassette with a long arm derailleur I jumped at the chance to do a long term test of the new shifting equipment.

There are two key qualities I look for when purchasing drivetrain components, namely functionality and long life. If a mech has incredible shifting action that means nothing to me if the first time it collides with a rock I have a long walk back to the car! In that respect the Zee parts have been faultless. Running a complete outer cable to prevent grime ruining the shifter seems to be working so far. I've been using the same cable (both inner and outer) since fitting way back in August of last year, meaning it's survived 7 months of riding including most of winter, not a regular occurrence! 

Still running sweet after a hammering at PORC

Since the setting up the gears with the wide range 11-36 cassette (Deore grade) they've remained maintenance free, somewhat of a rarity and a key reason why I love this set-up. A combination of work, studies and college mean what free time I have I want to enjoy riding my bike not fixing it. As a result the reliable and solid nature of the Zee gear more than makes up for the minimal weight increase over XT (12 grams for the derailleur) which can be saved elsewhere by having a smaller breakfast prior to riding!

The most anticipated feature for me was without doubt the Shadow+ rear mech essentially a clutch system designed to stiffen the cage to quieten down the bike. Although something you don't initially notice when riding the bike, the moment you hop aboard one without a clutch-mech fitted the difference is noticeable. It sounds as if you are riding with a bag of spanners dragging behind! 

Moving on to the shifter it is a well thought out desig, with comfortable ergonomics and a dimpled thumb release for extra grip with gloved hands. Although perhaps lacking the "snap" of a SRAM shifter, the gear change is both definite and smooth, with the multiple downshift being a handy feature when a climb sneaks up on you! 

Overall the both the mech and the shifter are well thought out and neatly executed however very much aimed at the gravity market and those wanting more than a double and bash at the front would want to look elsewhere. Shimano Zee is a bombproof, value for money alternative for those not wanting to shell out for Saint, keeping most of the features but not the hefty pricetag!
