What wheel I upgrade next?

As usual towards my quest for aerodynamics, I have always been finding ways to make my self and the bike more aerodynamic. I have already bought alot of one piece suit in the past few months and coupled with my POC Cerebel helmet, I think I am rather aerodynamic myself less my fats.
Hence this time round, I am making my bike more aerodynamic,  having one of the best wheels already, Zipp 808 FC front and custom 88mm carbon clincher with Onyx hub and sapim cx ray spokes, I feel there is nothing that I could make it faster other than having a disc wheel. However, I won't want to buy a real disc due to the fact I love the Onyx hub so much, instant engagement and minimum rolling resistance, what else can you ask for. So the only way is to buy a wheel cover as I have done before.
Here we go, Aero jacket from Wheelbuilder.com
Unpolished Captain America shield

Sorry for the mess behind. Fully set up. Simply looks so aero!

From my last post, I also mentioned about my classic steel frame project. From the picture above, you could probably see a sneak peek of the steel frame. I am still thinking about which colour to repaint, probably purple. Also there is a box of wheels at the back. That is my new built up custom vintage looking wheels for my Project Steel.

Yea some kind of new!

HSon Plus TB14 with 105 5800 Hubs and DT comp 2.0 spokes


































Reason why I choose this wheel is because of its vintage looking, does it strike a resemblance to the Ambrosio Nemesis? However this is a modern vintage. What do I mean is that it has wide rims technology while also having vintage box rim with eyelets and double walled. With the 32 spokes 2.0 straight guage front and back, its gonna be a bomb proof wheelset. We shall see the full set up when every thing is done and settled.

Revived

Have been through a hard year and finally I am back to posting.
I am still riding though frequency is low but the upgrading bug never stops.

The latest photo of my Cervelo P3 aka X-15. Ever since the last photo taken, I have changed to a Zipp 808 front wheel and a custom Onyx hub with 88/25mm rear wheel and also changed saddle to a PN2.1. Current set up is comfortable and pretty fast considered that I haven been training.

I have also sold my Pugsley and bought a classic steel road frame. Currently undergoing refurbishment so I won't take a photo of it till everything is done.

The silent upgrade

Usually for anyone that wants an upgrade on the bike, they will try to make it as loud so that anyone could see it but not for me this time. Especially for this component, it has been tout as the louder it is the better it is. So I guess you should know have guess what is it.

Yes the hubs. Particularly the rear hub, and that is what I am upgrading this time. Just the rear hub. But it has only been less than 6 months that I changed my wheels. Firstly, let me clarify, there is nothing wrong with the current Swiss Side Hadron 625 wheels/hubs. The decision to upgrade was purely for fun and I just want something special. The Swiss Side fairing makes a unique whistling sound when it gets up to speed and I think it is worth showing off to others rather than drowning the sound with the freehub ratcheting clicks. So I decided to get a Onyx Racing Products rear hub.

Whats with this hub? First of all, let me admit that by looking at the measurements of the hub, it not gonna be the best wheel in terms of lateral stiffness. But since I am on a tri bike, I suppose those aren't gonna affect me much as I am not going to be cornering like in a crit or am I going to be mashing on the pedals up a mountain. Secondly, since I am not going to be climbing like a mountain goat, the weight isn't gonna be affecting me (as usual). The weight of just the rear hub is equivalent to the weight of some high end hubs in a pair(front and rear). So why am I still choosing it?

The Onyx hub uses a different type of freehub instead of the usual pawls or ratchet. It uses sprag clutch. You can youtube how a sprag clutch works and you will see the difference. Some hubs uses roller clutch which looks similar but are very different. Roller clutch introduce alot of drag as compared to sprag clutch also roller clutch tends to have lower torque rating and tend to slip under power and might lock up during coasting. Sprag clutch doesn't have the above mentioned.

How about sprag clutch vs ratchet/pawl system? Sprag clutch has instant engagement which is extremely good for attacking and coupled with its silent free wheeling, you could probably sneak attack a person before he realised it but I doubt my bike could do that as the Swiss Side rims are too loud. The hub being silence also means that during descending, it has basically no drag other than bearings friction, so it will be faster than any other hubs out there. So basically its like having 2 front wheel.

Durability wise, they have been used for BMX for years so I guess it should be pretty durable. A chat with Onyx shows that they do not require maintenance and if you really want to maintain it, it can be done without needing special tools. Also I have choosen the dual sprag version which has even more durablity considering it has double the torque rating.

Did I mention that it comes with tons lot of colours and you can even customize it to your liking. But I am choosing anodize black just to match my front wheel too.

But so far all these are just theories, I got to wait till it arrives and then have it built up and test it myself. Lets hope it works as it is.

Fat bike again... same same but different

Once upon a time, I owned a fat bike, sold it.. and now, traded it again for my road bike(Lynskey Cooper aka Black Bird). Reasons for trading is for some personal reason. It was amazing that the Black Bird did not suffer a fate as me but only a crooked rail saddle, no scratches at all other than this. I have then trade the Black Bird to my friend whom I sold my old fat bike to for a fat bike! But not exactly the same thing, probably 80% of the bike is different including frame and rear wheel.

Initially my thoughts is to weight weenie it, seeing its potential of chasing the roadies with it. My opinion is as long as the pace is constant, the fat bike could follow but once the pace becomes irregular, its hard to accelerate and chase due to the weight. Managed to draft the roadies at 36km/h+ for the regular seletar loop. But after watching a video featuring Aaron Kwok advertising AIA insurance, its a bike touring video about a father and daughter, I have decided to convert it to fun bike to ride it with my daughter! I have also sold away my DIABLO(Bomb Track Arise).

So the results is as below...

Here comes the trailer. Sonia snacking in it

Confession of a cyclist

I feel happier whenever I am riding my black bird (Lynskey Cooper). It's not just because a titanium ride quality is better but also because it's a "slower" bike and whenever I can match the speed and even overtake the super bikes in my group I feel even more happier. It also gave me an excuse to ride slower than those super bike. I could easily blame it on the bike. 

With my X-15 it's hard to blame the bike and I could only blame myself for not being fast and strong enough. It's all out built for speed yet I am unable to gap the group. Sometimes I just feel angry with myself for not having enough training and being weak. The only blame I had now is to blame that my X-15 hasn't gone through bike fitting with me yet. So I have book an appointment to make that thing I could blame disappear so that I could focus on improving myself.

Swiss Side Hadron 625 First Look

Finally I received the wheels. 
The package is nicely done and looks different. Not the squarish box I have always received but in a box shaped like an arrow. Never mind these small details, what matters is the inside. I am proud to say this is one of the best package for wheels I have received. Other than the usual quick release and rim tape, it comes with extra 2 spokes for each wheel and also a removable core extender! This is awesome as even those high end brand comes with only a screw on extender which is as good as useless. It also comes with matching bottle. It looks even nicer and symmetrical than my newly bought Elite Cervelo printed bottle. The only downside is the bottle is a a smaller size hence lesser liquid but not a big issue as I have a Torhans aero z as my main reservoir. Have decided to go with a round bottle on the down tube due to during race it will be easier to replace rather than a proprietary aero bottle.


Now to the main stuff, the wheels! 
The wheels are well packed and they are very true and smooth rolling out of the box. The quality is well built too. Can't really nitpick for the price I paid. The fairings are stiffer than the ones on the Hed Jet though this also means it will be heavier. The wheels are laced with Sapim  CX Ray spokes which are the standard for high end wheels. The braking surface are well machined too. The decals on it is very nicely done too. They aren't the one big piece type but are cut nicely to follow the intricate design. The wheels are also the stealth version which fits better on a wider range of bike colour scheme. Now to the hubs, they uses straight pull hubs which looks nicer in my opinion. Cnc aluminium but that's about it. No fancy design which doesn't matter anyway.  The free hub and end caps are anodize red which is a nice touch. They are easy to work on too, pretty standard with most hubs out there. The sound on the free hubs are loud! It's quite personal whether you will or will not like it. To me I don't mind the loud clicking sound as it will be covered by the howling sound generated from the fairings. The howling sound increases it pitch with speed making it sound like a fighter jet which is pretty cool and it's the first time I experienced this sound even though I have used Hed Jet and cosmic carbone sl before. It's simply music to the ear and remind me to pedal even faster. 
Mounting tyres on it is very similar to the Hed Jet. New tyre might break out a sweat and require the use of a lever unless you have powerful thumb. As usual I used continental attack and force to maximise aero drag and crr for this set of wheels. 

Overall, it's a well built and well thought product. The only downside is probably a higher weight which isn't of concern to me. At a price of more than 2 times cheaper than a zipp 404 fc, you won't  find anything better. Aero data wise it is slightly better than the zipp 404 fc and just 3watts slower than the zipp 808 fc which is of higher profile. Weight wise unless u are all out for climbing, it won't make much of a difference compare to the zipp 404 fc too. So I think this is a better buy than the zipp 404 fc as it even has aluminium brake surface for reliable braking. Now the only thing left is to go out and ride them for real world performance. I will update again when i have done enough mileage to deem fit for the next review.

Types of cyclist

There are a few type of cyclist among my riding list and I am not even talking about Tri/Road/MTB differentiation. I am talking about the type of belief they have.

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.
