Going tubeless

As far as changes to my bike go, it's all been rather manic! After writing off my previous 6 year old rim I decided to update my wheel/tyre system to something far lighter and a bit more up to date. Some online research and a few phone calls later and a lovely set of Hope Hoops were on their way to me: their uber-reliable Pro2 Evo hubs laced up to Stans No Tubes Flow Ex rims. I chose this wheelset as I wanted reliability and strength matched with relatively light weight (1880g), something this wheelset gave in spades. Whilst I was at it, I decided to refresh my tyre choice as well moving away from my trusty high rollers, instead fitting a set of Schwalbe Hans Dampfs. This is Schwalbes brand new all condition tyre, something I was excited to try out.

I decided to go tubeless at the same time, using the Hope/NoTubes conversion kit for the Flow rims. This is a fantastic piece of kit and proved laughably easy to set up. It was a case of sticking the tape firmly down in the rim bed (I left the original cloth rim tape on), fitting the valve stem and seating the tyre sans sealant and finally adding sealant and inflating. The whole procedure was trouble free and simple but that could well have been down to both the tyres and rims being brand new.

I am running the Hans Dampf tyres at roughly 30psi at the moment however I expect I will drop them down further but my initial impressions were very good! The first proper ride was at some local (ish) downhill trails where the conditions were muddy, chalky, wet and horrible! The tyres gripped well and slid predictably whilst staying composed on roots, everything I wanted from a tyre! I dropped pressures steadily throughout the day yet never experience burping. Having said that we stayed clear of the big jumps due to the conditions.

Overall both the wheels and the tyres are very good: they're reliable, strong, light and easy to set up tubeless.  If you're looking for a reliable and relatively lightweight wheelset for less than £350 then you can't go far wrong with the Hope Hoops for all mountain riding, but more XC orientated riders could get lighter if they are willing to sacrifice strength! A few months down the line I'll post up a long term review, to see what shape the components are in after some serious hammering!

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!
