Redline CX Final build.



Boom here it is, my complete bike, race ready all set up ready to go.
There have been quite a few changes to it since the first instalment so ill show and explain why I have changed those parts.
This is a list of everthing in this pic.
Redline CX frame
Alpina CX Carbon fibre forks wiht alloy steerer
Hope Pro 3 hubs
Stans no tubes ZTR alpha 340 rims 28h, DT swiss comp spokes
Stans no tubes tubeless sealant.
Vredstren premiato 700x30c tyres
Sram Rival Cx cranks 170mm 46-38t
Crank bros Egg beater pedals
Controltech 100mm stem -5deg rise
Shimano dura ace 7700 Shifters/brake levers
    "             "           "      Front mech
    "             "           "      Rear Mech Short cage

Zipp service course sl bars size 44cm with a short and shallow bend
Zipp service course CX bar tape
Selle italia Flight saddle
Did have an Easton EC70 carbon post but the set back (lay back)
   was too much so just got some no brand post on.

weighed the bike the other day and i have dropped a fair bit from the start weight.
it started off about 22.9 lbs
and is now 17.4 lbs which is pretty sweet!

heres some more pics...



The Sram Rival cranks that i changed to was only due to the other cranks , Shimano dura ace 7700 175mm, being too long for me.  I was doing a fair amount of rides and my knees started to really hurt. I tried lower saddle position and my knees hurt the same tried higher and my hips started to hurt as well so I figured that I really needed smaller cranks. since the swap, no aches or pains..well except from the usual cycling pains i.e jelly legs, sore legs, nausea...etc.
I choose these cranks because I don't like the look of the new shimano cranks, Ultegra, 105, in my price range. I obvoiusly wanted the shiny carbon Sram Force/Red cranks but slightly pricey and the thought of bashing carbon cranks on rocks and destroying them doesn't sound awesome.

Hope Pro 3s on Stans ZTR alpha rims were a pretty cool idea also. Hope hubs were a must for CX racing.
Iv used them in DH riding/racing and have known almost every person iv rode dh with to have used them and i haven't heard of anyone who has had any problems with hope hubs.. if they had it was quickly fixed due to the availability of spare parts and ease of assembly/disassembly. The seals in these bad boys are also dam good which is useful in muddy conditions. Alpha rims were chosen because of the tubeless tyre setup design and are pretty light..370g a rim.




Zipp bars because the older bars bent and flexed way too much for my likings. I also dropped from a 46cm to a 44cm. Not intentional,  but because i miss calculated the size of the other ones...the writing had rubbed off.  Still not 100% sure if i prefer them wider or narrower but i reckon that if i went wider again, it would feel weird.















And thats that...
Tune back tomorow to find out if i sucked or not!

The Ride (bike #1)

Redline CX

Here it is! This is my cross bike #1. I have two cross bikes, i will take a pic of the other one at a later date.
this is my favourite of the two mainly because its lighter and rides better, but also because it has the better components on it. I was lucky enough to have been given this bike from my Bro out in California as it was his old bike and didn't need it any more. Cheers Mark!

Many people will think that this is just a road bike. If you look closer, you will notice a few differences. Cross bikes are to be ridden mainly off road so, this requires a few subtle differences over a road bike.
The first and most visual thing that sets it apart is the brakes. This has canti-lever brakes whereas road bikes have smaller more aerodynamic calliper brakes. The only reason for having these bigger brakes is to allow for  better mud clearance. i.e. stop mud gathering at the brakes making it almost impossible for the wheels to turn.
   Another difference is the frame strength, due to the off-road demands, the frame is overbuilt, mainly around the head tube on this frame, just to stop it from snapping or bending.
The frame seat and chain stays are also a little wider to also allow for better mud clearance.

My bike currently has a road setup, with road slick tyres and a bigger chainring. this is purely to achieve higher speeds and make it a bit easier. For the cross season i will put a smaller chain ring on and put on some nobbly off road tyres. I'll go into that more a bit nearer the time.

This is a pic i took today but it is not how it will stay. I have a few upgrades planned which should come fairly shortly. I will post pictures of each new thing. It weighs about 21.5lbs at the moment and i will be looking to get rid of some of that weight.
Heres a list of the bike and components:
 - Redline CX Frame and fork
 - Alex hubs on Alex AT450 rims (soon to be replaced, and stored as spare wheels)
 - Dura Ace 7700 Groupset ( Rear Mech currently not on it but will put that on soon)
 - Shimano LX brakes
 - Time Atac pedals i think. ( i use these on road but will change to crank bros 'egg beaters' for off road)
 - Profile Design stem and bar
 - Easton EC70 seat post
 - Selle italia Flite saddle

and thats pretty much it. I dont know what tyres, cant see anything written on them from the sofa and im not moving. 
Hopefully you'll stick around and follow my progress and find out how much bike weight i can drop, if at all. and also at what cost! Also i will post some pics of bike #2 very soon which i want to get rid of some weight at little cost.
You Stay Classy readers....
