Norco Sight: New Chain Ring and Chain Guide

I've just got  two new components for my Norco Sight: chainring (e13 Guidering, M Profile, 32T) and  chain guide (e13 XCX Top Guide Black BB Mount).
I've changed my 34T Race Face NW chainring for another one, because 34T was too much for me. 34T chainring was good with 26" wheels of my previous trail bike. Norco Sight has bigger wheels, that's why I've decided to change the chainring for 32T (e13 Guidering, M Profile). A weight of the ring is aproximately 45gr.

Final Wheelset for my Norco Sight

I hate when a bike has different wheels, that's why I've decided to change rear rim om my new wheelset from WTM KOM i23 650b to Colt Element 27.5" rim. Now I have similar wheels but with different hubs (ZZYZX 15mm + Novatec 142x12). Colt Element rim looks much more stronger than WTB KOM though Element is only 15 grams more heavy.

Final wheelset for my Norco Sight with Maxxis Highroller II 27.5"x2.4" 3C/EXO and Avid G2CS 180/160mm rotors:

Weight: CS-HG81-10 vs CS-HG62-10 Shimano Cassettes

Stock cassette of my Norco Sight is Shimano CS-HG62-10 (11-36T). It is rather heavy cause its weight is approximately 460grams:

Weight: Avid HS-1 Rotor 180mm

While my bike don't experience any upgrades, I post some information about some component's weight.
Avid HS-1 (HS1) 180mm rotor weight is about 135gr. It is 15 grams lighter than stock Avid G2CS rotor of my Norco Sight.
I don't like how HS-1 rotor looks like, that's why I will install it  on my training wheelset.

Weight: Wheelset of Norco Sight A 7.2 2014

Norco Sight A 7.2 2014 stock wheelset consists of ball bearing Joytech hubs (15mm and 142x12) and Alexrims TD26 650b (27.5") rims. Alex rims are not too heavy, their weight is about 460-470gr. Front hub weight is about 290gr. I haven't got rear hub on a scale but it's weight must be 450-480gr.

The whole wheelset weight is 2200gr.

New Handlebar for My Norco Sight: Kore Mega

Norco Sight A 7.2 2014 comes with very convenient Norco 740mm handlebar but it's weight is approximately 400grams. This handlebar was emmedietely replaced with my old Azonic World Force 762, which I've been using for 4 years with many of my bikes. Azonic World Force (762mm, 1") weight is about 345gr.

Finnaly, I replace my old handlebar with my freind's Kore Mega 760mm:

My Vintage Singlespeed Road Bike (ХВЗ Start-shosse)

I've just got a new handlebar tape and  U-brake for my non-fixed gear bike, and I've decided to make some modifications.
MTB riser bar is rather convenient, but sometimes I want to get lower riding position, that's why I've decided to put stock Start-shosse drop handlebars with new white tape. I've also installed 16T singlespeed rear cog with front 39T chainring and new U-brake. The bike is a little bit lighter now (11.04kg/24.34lbs) with very heavy steel seatpost and wellgo b-54 flat pedals (I use flat pedals for city-biking).

New Tyres for My Norco Sight: Maxxis Highroller II

My Norco Sight A 7.2 comes with Kenda Honey Badger Sport Tyres. These tyres are rather good but I'll leave them for cross country and light trail riding.
While there is a big sale in most of bike stores now, I buy a pair of new Maxxis Highroller II 27.5x2.4 with 3C (Max terra) compound and EXO protection.
Maxxis website tells us that this tyre weight must be approximately 890grams, and this seems to be the truth, cause my tyres' weight is no more than 920gr:

Weight: Kenda Honey Badger Sport 27.5x2.2

Norco Sight A 7.2 2014 comes with Kenda Honey Badger Sport 27.5x2.2 tyres with 60TPI casing. These are rather lightweight foldable tyres for dry conditions.  They easily become tubeless with "ghetto tubeless" method. I like them very much and I'll use Kenda Honey Badger Sport tyres for training and cross country riding, but for enduro competitions I will buy more agressive tyres with protected sidewalls.

Kenda Honey Badger Sport 27.5x2.2 (650B) tyre weight is approximately 680-690grams (1.5lbs).

This is my rear tyre:
