not sure about other power meters, but on the Ergomo you need to reset the trip before the ride or it can think you are on one very long ride with a big break. Did you perhaps activate the power meter before or after the ride ? You should be able to see this on the chart of the ride- it will show you where CP thinks the break is. Out of interest, pls post your power info!

I have a set of the OG-Ti's. I actuallt prefer them to Dure-Ace- I find them more progressive and easier to modulate, even on Carbon rims. I find stopping power is about 85% of DA. They work well, look very cool and weigh nothing- highly recommended!

Did they manage to sort out the dust seal issues ? I understand that there were a couple of failures on last years epic due to this. I need to decide on Pace or new Sid in a few weeks time

I am surprised that a good corporate citizen like Barloworld would sign a doper to their squad. But then given the risk of bad publicity around sponsoring pro cycling and drugs it is amazing that they sponsor cycling at all.

cool pics, thanks guys. Do they still have athletics at the same time ? Last time I raced (late 80's) the ace SA sprinter (I forget his name) was doing the 100m- very impressive.

yes use it as many times as you like. I take mine off after every couple of rides to clean the chain.

Hi Guys, Quick update on the two Ergomo's that I know about that were running at Sabie this weekend- Both worked perfectly through all of the mud and rocks. I have now used my Ergomo for 2 multi day mountain bike events and it has worked without hassle on both of them. Couple of things: - I am going to try and move the cable that runs from the bb to the computer to the top of the downtube rather then the bottom to better protect it from rocks. - Despite claims on battery life, I only ever seem to get 8-10 hrs out of it assuming I dont use the backlight (then it is more like 6hrs). - Still looking for a long lasting solution to securing the cable as cable ties can squash it (happened to my first unit) and tape can come undone if you use a power washer to clean the bike....

IF you want something relatively robust, either the new SID or the Pace (they seem to have sorted their dust seal issues). Both only available in SA in the new year, suspect about 1200g each.

From my personal experience with two Ergomo's: road bike for almost a year and mtb for a couple of months and I am very happy. So are the other Ergomo users that I ride with. Only issue I have had is a crushed cable (cable tie too tight), corrected by the agents. If you want a relatively low cost unit that you can use on multiple bikes, with any wheels and disk brakes when needed, I dont think there is anything to compare. Take Sabie this weekend: I would need 2x powertaps one for each wheelset. Downside is that you need to run old style cranks to cater for the BB, these can be tricky to find especially if you want something light and that can fit Rotor rings. I am definitely watching the Quark with interest- it looks like it had the benefits of SRM design with Ergomo computer and much lower price. Problem is from what I read, there is no mtb version on the horizon. Of course if I win the lottery, I would get SRM's for the whole fleet!

I have a different take on wheels. I bought my "race" wheels expecting to only use them occasionally (I dont do that much racing). They are so awesome to ride that I end up using them every day except for dark winter morning training rides. If you keep them for special days only in 2 years you will find there is a new-new thing out and you will want to get rid of them anyway. I say buy them and ride them whenever you feel like it!

nice!, what wheelset ? I have ZTR olympics and tune hubs that are super light and have been bullet proof for 1.5 seasons. Highly recommended.

You need to be carefull with published bike weights and real world bike weights. The published numbers are generally not for ridable bikes, especially the choice of tyres & stans, bar ends etc. I suspect that the quoted weight of the new scalple of 8.5kg is not real world achievable. My titanium hardtail is 10.0kg as I ride it. It will lose about 300g with a few more trick bits (new SID's or Pace). Any lighter and reliability will suffer. If I recall my Ali Yeti was 11.2kg with nothing too exotic.

Hi All, Can anybody tell me show I can create mean maximal power charts for multiple time periods on one chart ? For example, I would like to see how mean maximal power for this month compares to mean maximal power for last month. I can do it for 1 time period but cant get 2 time periods on 1 graph. If I recall Bruce posted an example of something similar a while back. Thanks, 1kTT2007-11-16 12:58:16

whats the all in cost for a power tap again ?

325w normalised for an hour sounds right based on my power stats for the season. One morning when it is raining and I feel brave, I will try 2x20 mins and see. Out of interest what sort of gradient would you use on a COmputrainer course to do the test on ?

Hi Guys, Interesting discussion. I will post power stats for the other two stages tonight. Bikemax, I was talking about my 20min Normalised Power output as FTP (apologies if this is not the correct term). I calc it by looking back at my seasons stats from the Ergomo downloads. Best ever was 384w (in the road section of the winter classic), next best was 350 (in the zoo lake crit)- those were my only road races this year. If I look at my power histogram for training rides and then look at when there is a drop off in power, I get +-340w pretty regularly. I pretty often get NP just above 300w for 1h45 training rides. I am pretty sure that the drop in power over the last hour was due to terrain, I actually felt better over the last hour than the 1st hour. Simon

An Ergomo pro. I had to shave down the bb on my MTB from 73mm to 68mm and then I use the same computer as on my road bike. I am sure that if it coped with Cederberg, it will handle anything fine.
