Firstly, the weight weenie. These are the kind of cyclist that count grams. I think they are very common all around the world. They spend $ to make their bicycle as light as possible. However, in Singapore where they aren't any real prolong climbs that they can utilise their bikes. Funny thing is, these type of cyclist usually are the ones that can't climb fast when climbing. Coincidentally, these are also the type that like to zhng their bike nice nice and colour coordinate everything on the bikes. Their motto is probably, can't ride fast.. look fast. One finger carry bike and take photo in the most relax looking way. These cyclist are usually spotted in the middle of the group and sprints whenever there is chance but seldom pulling.
Secondly, the aero-weenie. I definitely belong to this group. This group of people are the ones that likes to ride fast. Usually, their bikes belongs to the aero type, be it TT or aero road bike. Usually seen at the front of the group rides pulling and riding fast to separate the weaker drafters as they won't help in making the speed higher but instead slow down the peleton. These guys have a totally opposite taste as compared to the weight weenie. Weight usually isn't an issue to the aero-weenie. But anything that can make them aero-er and save watts, they will do it. For myself, I wear a one piece cycling suit from Castelli. I wear aero helmet. I try to streamline anything I can on my TT bike and put accessories that helps smoothen airflow even though they add weight. These are some of the stuffs that will make a weight-weenie jump if spotted on their bike. These guys motto are aero is everything!
Thirdly, the comfort-weenie. These cyclist are usually spotted with heavier bikes and anything that can increase comfort. They have heavy bikes and usually ride at the back of the group taking their time to reach the destination. Some giveaway items that tells u they are comfort-weenie are big fat saddle with cushion or even springs, double wrapped bar tapes, fat road tyres(28mm and above), music on their bikes. They can be spotted from far as they have a rather upright position and usually also wears loose fitting comfortable jersey. They can be very adventurous, and seen riding on off beaten tracks and some are even miles crunchers. They clock lots of mileage(usually slow) and food and relax is their motto.
Lastly, the hardcore cyclist. These cyclist are respectable as they ride anything and can ride very fast. They do not rely on technology and sometimes can be been on low end bikes or even very old bikes though some ride on high end modern bikes too. They usually have very strong will power and endurance. The parts on their bikes can be mixture too as they just replace anything that breaks and doesn't care about the looks of their bikes. Their motto is as long as it still rolls.
The Canyon Aeroad CF SLX 9.0 LTD and Canyon Aeroroad CF SLX 7.0 as being tested in the TOUR magazine. Why this 2? The reason why I decided to choose this 2 models is due to it being the most similar. Its the exact frame and fork just with different components.
The 9.0 LTD comes with DA DI2, H11 CF aero cockpit and 404s and TOUR tested them to complete a 100km route with 2km elevation gain in a timing of 4:15:29.
The 7.0 comes with ulterga 11, H16 alu cockpit and Mavic cosmic carbone SLE and complete the same route in 4:16:40. With an upgrade to Swiss Side Hadron, it completed the route in 4:16:27. I reckon the change of wheels will drop around 71g from 7.2kg to 7.13kg. This also includes the change of original mavic tyres to gp4000s II. But I wont go into that as Mavic reckon their tyres together with their wheels are faster than with other tyres.
As a comparison of the aero bikes doing the mountainous route, a climbing bike at 6.8kg with round tubes and 40mm climbing wheels will need a time of 4:17:54. Hence aero still triumph weight unless it is a pure climb.
In another TOUR test, the Swiss Side Hadron 625 tested the same as Zipp 404 FC in terms of aerodynamic. But the difference of weight between them is 185g.
Between the 9.0 LTD vs 7.0, comparing the weight of the di2 and ultegra. The difference is 253g. I suspect the between H11 and H16 cockpit. The carbon are heavier. Which offset the rest of the weight. This can be confirmed by comparing 7.0 DI2 with 8.0 DI2, they have the same component except the wheels and handlebar. Comparing 8.0 wheels, they are reynolds strike slg which is lighter than the SLE on 7.0 But overall weight, it is more than 100g difference with the 8.0. Which is why lead to my conclusion that the CF bar is around 100g heavier than the alu. But the CF bar is way aero-er.
So with the above findings, I conclude that between the 9.0 LTD timing of 4:15:29 vs the Swiss Side Hadron 625 7.0 timing of 4:16:27 which is a different of 1min 2seconds. This 1min 2seconds is an advantage that the 9.0 LTD owned that comes from being around 300g lighter and cleaner and aero-er cockpit(DI2 cables run internally). Aero-ness of weight doesnt count as both the SS and 404s are of the same.
Take note that the simulated route is a mountainous one, so the time difference might be more due to the 300g difference and also the aero-er frontal of the 9.0 LTD which I think saves more time than the weight difference. If the route simulated is a flatter route, the time difference will be even smaller as weight advantage won't weigh so much anymore.
Extra bonus: The HED Jet 6 plus is faster than the Zipp 404 FC on a Cervelo S5.

The upgrading bug never seems to cease. This time round I have gotten myself a new shoe again even though my current one is still in very good condition and my older one is still also in a good condition. Don't ask me why am I upgrading again. I have no idea too. Perhaps it's because the R171 looks better. Indeed when I receive the shoe, it look so even better in person. When I put it on, it wraps around the feet snugly like a pair of well fitted compression socks. Shimano never fails to amaze me with their shoe technology. I have owned 3 generation of their shoe and with each new generation, it just seems better. The R171 is more aerodynamic, no loose flap around and its comfortable without socks too. Now wait till my new wheels arrive before I wear them for rides and give a ride review.
Something new coming up is a Mio Link heart rate monitor. So why did I get it? Because my wiggle order lacks $$ to hit free delivery. So instead of paying $24usd for shipping, I paid $95 for something that might be useful to me. I have never trained with HRM and the last time I owned one is years ago with the Edge 705. One thing for sure is I hated wearing a heart rate strap. The Mio Link doesn't require wearing one, it simply uses optical light on the wrist to monitor heart rate. Using led, it also shows you your zone. With this, I will probably get motivated to kick start my training regime again. Which means lots of zone 2 riding and enduring other rider passing me. Let's hope the mind is strong.

|HED JET 6 FR with decals removed|
As of 2 years later(2015), I still think my initial review still stays the same. There is simply nothing much to nitpick. The wheels are solid built, 2 years of riding and still as smooth and true as day 1. I especially like the alu braking surface which has become a criteria of my choice of wheels. The only troublesome part of a alu braking surface is that to keep it shiny, there is some hard work to do after a wet ride. The wider rims with its wide internal width makes the ride more comfortable and aero when paired with the correct tyre(Attack & Force). Although 23mm seems to be outdated in 2015, however I still think its more than enough. A testament could be seen from Swiss Side Hadron, a 23mm wide rim too but is tested as aero as a 808 FC. So I think 23mm is the perfect width in terms of low crr and aero. The hubs are also very smooth rolling and definitely doesn't require the need of upgrading to ceramic, not to mention its also easily serviceable. The weight is good for its depth and comparable to full carbon clincher of equal depths. This is due to the use of lighter materials for the FR version.
In summary, this is a wheel I would get again if the Swiss Side isn't up to my standard. Now I can only wait patiently for the Swiss Side to reach me probably in 1 month time and then I could give a good comparison between the 2 ultimate wheels.
Tuesday, 31 March 2015
1) Swiss Side Hadron 625 (Replace HED JET 6 FR. Testing shown the Swiss Side is almost as fast as the 808 FC despite the lack of depth and its faster than the 404 FC.)
2) GP Attack & Force (Replacing my used GP Attack and GP4000S II. Choosing Force over GP4000SII due to testing shown the Force lower CRR will have more advantage over the GP4000S II aerodynamic properties.)
3) Speedfil R3 rear hydration (To replace the profile design RZ2, as its too hard to remove and insert while riding so its as good as not having a hydration. Has removed and replacing with the Speedfil R3)
4) Wheels Manufacturing PF30 Angular Contact Bottom Bracket (Replacing the stock BB)
5) Hawk Racing Shimano 11 Speed Jockey Wheels (Replacing stock dura-ace jockey wheel)
6) Shimano R171 in a smaller size(43) as compared to my current(43.5) as I intend to ride without socks and I feel I could go smaller half a size. Hopefully it fits.
