To crudely simplify things, a triathlon/TT bike position is much the same as a road position, but basically "rotated forward", so your arms rest atop the very-low-set bars. A consequence of this is, the seat ends up further forward. (source) Using Chris Froome's TT position as an example, noting the hip position versus the bottom-bracket position: ...

I think most people find the bike-to-run transition quite difficult while the legs adjust from going in a circular motion to running. Particularly for longer distance courses. Here's an interesting article from a renowned triathlon athlete/coach: http://www.trainingbible.com/joesblog/2007/01/cleat-position.html The article discusses the merits of putting ...

In the same way you train for your running you'll likely want to vary the rides you do on your bike. Bicycles offer you the same options like: Tempo ride: stay just below your lactate threshold Interval training Find a long flat section of road Go above your LT for a bit, then a little below for a bit (stay above 70% of LT) Many times this is 1 minute ...

You probably don't want to spring for a specific time trial bike straight out of the gate - you might hate the triathlon experience, for one thing! Given that you're planning on using the bike after this events, albeit possibly with other events down the pipe, I'd be looking for something that you can get the best use of after the event. So a road bike ...

They are primarily used for high-performance road bikes for smaller riders. There comes a point where a proper fitting frame for a smaller rider will have strange handling using 700c wheels. 650c wheels are designed to address that. Smaller riders can also have road bikes built with 26" wheels. So if you are of average height there is no significant ...

Triathlon bikes are about one thing, and one thing only. Aerodynamics. Dan Empfield, the creator of the Quintana Roo brand, recognized this early on. Cervelo came along soon after, and their designs basically changed how time trial bikes are viewed, with their breakthrough design of the P3 in 2001 (Company history here.) This P3 design evolved, and there ...

Budget advice Visit/Join a Tri Club and check out what second-hand bikes the members are selling. Aim for the low end, say less than $1000. Make sure you ride a few different bikes so that you can compare. It needs to be comfortable and fit well. It must have quick-release wheels. Also, work out what shoes and pedals you are comfortable using: will you ...

Looking at your times, your times on the bike leg are below the levels you are setting in the other legs. But given that you are barely training for the bike leg, your times are pretty good. This site says How long does it take to finish a Half Ironman Triathlon? The answer, based on our analysis of more than 67,000 finishers in 40 Half Ironman ...

What you want are satellite shifters or the TT shifters. I believe they just plug into the standard brake/shifters.

I have been considering this question lately. Here's my input... I understand that 650 wheels have advantages because: Less weight, less inertia. The less weight there is the easier it is for the wheel to accelerate, turn and climb. I understand that 650 wheels have dis-advantages because: Less popular than 700 & 26" with retailers, so potentially ...

There are many factors to consider. Without being able to be scientific about it, people do evolve a natural pedal technique and I don't see the point in trying to radically change it, rather you should first have your bike fit and set up performed properly, and then allow your own natural style to evolve. There have been major cycling champions that were ...

I would think that it isn't much that cycling has over running if you already are an accomplished runner but it does have it benefits. cross training would definitely help get over plateaus and would also add an element of fun into your training. hill climb rides would help stretch your endurance and give your quads a good burn. as mentioned, a cycling club ...

If possible, borrow a second bike, and perhaps a trainer. There is very little that you can do to effectively warm up in a cycling effective way, other than ride. A light jog, and some stretching is the second best option. It is a short enough ride for that to suffice, if it is your best available option.

Its only 13K, so you do not need to much of a warm up. However, the purpose of a warm up is two fold. One get your aerobic system going, and second to get exercise specific muscles warmed up. For the first, you can go for a light jog (not in your bike shoes please!) and for the second, it is best to ride to match the muscles, and running muscles are ...

Aside from getting a TT specific bike, 1) Get a new seatpost which allows for more saddle adjustment 2) Get a new saddle are probably your options best options. I don't think the padding will help. When you added aero bars, you changed the riding geometry, and pretty much aside from swapping out stems/bars and tweaking heights there, your only other ...

In addition to aerodynamics, not yet mentioned is the benefit to your running off the bike. By changing the seat angle, you use your muscles differently and can run faster off the bike than a more traditional seat post angle. As noted in this article, test subjects were about 5 minutes faster in a 40k/10k Brick (stationary bike/treadmill run). There was ...

Since this might have really been a question about 650, I am going to answer if from perspective of why use 650B. 650B is common in Randonneur style bike, currently one of the more popular types of bikes being requested in the handmade bicycle market. 650B allows the use of 42 width tires with full fenders, big tires even at low pressure with 650B become ...

I'm in the USA and mostly ride on 700's so that is the angle from which I see this. 700C wheels are larger and will require slighty less energy to make them go round and round. If you have a really small frame (like an XS), though, these 700's may be large enough to cause toe overlap. In this case, you're hitting your toes on the tires when going around ...
