Setting up bike for TT(6 posts)

Setting up bike for TTChrisA
Apr 30, 2002 11:51 AM
I'm doing the Fitchburg/Longsjo stage race this year, 35+ catagory. The first stage is a 7 mile TT, which has one 100 ' rise over 2 miles. I don't have access to a TT bike so I'll probably use my road bike. The bike is a Cannondale with Ksyriums (bladed spokes). I'm looking for suggestions for any modifications and adjustments that could be done and would be worth the effort given the short distance.

I'm thinking of lowering the stem by removing the 2 spacers and putting them above the stem. I have an old set of TT bars (with no provision for shifters) that I could bolt on. I'm not sure about seat adjustments. Thanks for your input.

Add the aerobars. I'm not sure I'd mess with the stem height, especially if you have to yank the aerbars off for another stage and put the spacers back on. Your time between is probably better spent resting.

If you use aerobars, you might want to move the saddle about 1-2 cm forward, and then up slightly to get the same height relative to the pedals.

However, I'd not do any of this unless you'll do some training rides on this setup and get used to it. The TT position uses some different muscles, and requires different skills.

Other than that, I'd use a skinsuit and keep the tip zipped up.

I personally lower my bars about 2.5 inches lower for TT's. It is kind of a pain to switch it out between stages in a Stage race, but it helps put me in a more aero position. I like the bars a little higher for comfort when it comes to the road race, but for TT's up to one hour, I am plenty comfortable on the aerobars. As far as the seat goes, I move it forward about a centimeter for the TT and move the seat up slightly(less than a cm). This works well for me with Syntace bars, but other bars put could put you farther forward or back depending on the design. For me, I put my bike on the trainer and tinkered with the fit until I found what was comfortable. Good luck.

I do a short stage race once a year that begins with a short time trial also. I don't lower the stem, cause it will not go any lower, but I would if I could. I do use the bolt-ons and they will make you faster on those flats. I also switch the seatpost around so the offset is going forward. This seems to help too, you just gotta measure everything so you can return it to its proper position after the TT.

For the distance you're talking about, moving the seat forward isn't going to help much unless it's waaaaaaay back. Just ride forward on the saddle and gut it out. No real need to mess with the handlebars unless you've got them near the saddle level. Narrow is going to buy you more speed than low at this point. Definitely take a couple rides with the clip-ons so you're steady on them (remember, steer with the shoulders, not the arms). The TT is going to be short enough that it's not going to have a HUGE effect on GC, but it could make all the difference in the top placings.

Personally, I find that I get the most power by just keeping my saddle in its normal road position. I use a set of clip-on aero bars added to my road bike whenever I have to TT and found that when I moved the saddle forward on the rails it actually became more uncomfortable to get into the tuck and begins hurting muscles I don't ussually use (strange little ones on my hip and on the side of my leg???). When I discovered that I could get into the tuck just as easily with my normal saddle postion (and a fairly deep tuck at that), and also get my normal power output with that setup as well, I never looked back. I'd say try to use as close to your normal setup as possible (you'll have the most power this way), but at the same time try to get as low as possible and definitly use the aero-bars as well...they really work (~2mph faster at the same percieved effort when going into a headwind for me).
