Is it normal for Profile Aerobars to fail so quickly(7 posts)

Is it normal for Profile Aerobars to fail so quicklybimini
Dec 8, 2003 5:48 AM
I bought a pair of Profile split Second aerobars on ebay this year.

They were in like new condition but they have worn out in 3 months of heavy use. First the springs failed that flip up the am arm rests, no big deal. Now the pins that hold the arm rests on, fall out. I also noticed that there was a bit of alluminum coming out when I unbolted the bars (thead wear) so I leave them bolted on most of the time.

Are these normal problems? Is there a good fix for the arm rests? I may try running a thin bolt through the holes and just bolting them on. Does anyone know of a good fix for these bars?

I ride every day and normally alone, so I play beat the clock a lot. I like to go aero and the split seconds get me in a good possition but I'm not happy with the problems and the noise the arm rests make on rough roads. Should I expect this with any bolt on bars? Is it time to look at a true TT bike?

well, I do see alot of the arm rest springs. I went to Lowes and found some replacement springs in the hardware section. I don't know what they are called, but you can find them in the drawers in the hardware area.

As for the pins and threads. I have not seen the pin problem that you mention. I suspect it is caused by the constant adjustments brought on by removing them and putting them back on. Alu threads do not hold up to heavy use, taking them on, taking them off. I tell most of my customers that I do not recommend it. If they must, I suggest that they consider the Syntace bars, much fewer moving parts.

Why do you bolt and unbolt them so often? Does your club ride not allow them? Do your roadie friends make fun of them? Do you just not prefer them when riding with your roadie friends?

In answer to your last question, Absolutely! Sounds like you may want to consider a new (or slightly used) bike, but maybe not a TT specific model. Not one with 650 wheels, forward angles and etc... I suggest to my customers not to switch from 78 to 74 degrees too often as it undermines training goals.

From what I put together from you, you are not racing Tri's or if you were, there would be no need to bolt and rebolt so often. How about this idea, why don't you dedicate your current ride to your solo TT efforts and buy a sweet new road bike?

They guys I ride with who use aero bars are constantly replacing springs, pins, etc. and fixing bars with duct tape or jury rig fixes. Can't give you a number on "how long they should last" but they don't seem the most reliable of devices. Also can't say that this is brand/model specific caution, as I haven't kept track of what is failing. Just a general observation.

... Profile has reworked the bar interface on many of it's aerobars... and they're much better than the earlier stuff (had Split Seconds... now using Carbon Strykes)... but anything less than an integrated aero setup is going to be a bit more fragile than bars alone (for the most part, they're not designed for high torque or high load (like in climbing or sprinting)).

I've never used the flip up pads on any of my bars so I can't comment directly, but a bud has had just a tad of an issue with his over the years. Do your bar clamps resemble the one in the pic?

A true TT bike can be an expensive and limited platform... I know a lot of folks who are quicker on a standard road than I am on a P2K with aeros!

Be the bike.

I will probably just bolt the pads on solid, I don't need the flip ups. I have the pads as far towards the center as possible so there is still room for the hands on the top of my bars.

Yeah, there are a couple of CAT 1 riders I race with at times that come to the small races I do just for practice. Currently my best 40K TT is just under 1 hr 2 min. These guys show up on a road bikes with out aero bars and trash my times, (low to mid 50's). These guys could ride a Huffy and beat my times.

But, since I put the bars on I found I ride on them most of the time during training. The exceptions are when I am sprinting from stop light to stop light or when I'm climbing steep hills. I do notice the difference. I also like them in the cold weather. When I am down in the tuck I stay cozy and warm. Most of the air is hitting the top of my head. Soon as I raise up a bit I feel the air on my chest and the cold.

I do take them off for group rides and racing. (haven't raced for a couple of months). I am worried about the clamps that hold on the bars wearing out.

I am thinking seriously about piecing together a TT bike out of older technology parts or getting a bargain TT bike on ebay. The UCF rules have changed the styles of the new TT bikes so there seem to be some bargains to be had on TT stuff that is not UCF legal but is still USCF legal.

I have a set of the Profile Airstrike 2000 (or something like that) that also have the flip up pads. Profile had a problem with the Z brackets and about a year ago actually had a recall. My brackets had the pin holes drilled improperly and one broke. I contacted Profile and they sent me a new set. As far as the weak springs, I got rid of the rattle by hooking a small bungie cord between the brackets, just below the pads.

Profile in the mid-90s had a lot of QC issues. This is not unusual for Profile bars from that era.

I replaced a horrible set of Profile Century clipons with Syntace Streamliners, have not had any problems with these. I'd recommend upgrading to Syntace..
