Bladed carbon fork owners? Computer install difficulties?(10 posts)

Bladed carbon fork owners? Computer install difficulties?aliensporebomb

Hello.

I've got a new Giant TCR2 which comes with a bladed carbon fork. I'd like
to know what brand and model bike computer you are using with the bike
since I attempted to install a Specialized Speed Zone tonight and realized
that the sensor that clamps to the fork is WAY too bulky and there won't
be any clearance between it and the spoke mounted magnet. At all - I even
tried putting the magnet on the spoke farthest away from the magnet and
it's still too close.

My wife had an extra Vetta RT55 lying around for her recumbent and the
sensor on that is a lot smaller than that of the Specialized but I can't see it
working too well either - the clearance between the sensor and the magnet
will still be too close for comfort. Maybe. This is her old computer and it's
sort of broken at the moment.

Anyone with a Giant TCR series with the bladed carbon fork or similar run
into problems like this? What are you using? Wireless? Wired? Brand?
Model? I really need to do mileage and stats for training purposes.

my friend does that with his Cateye Mity 3. the band on my Shimano Flight Deck goes all the way around the fork.
I just got a Mity 3, and it does come with an attachment for aero forks. the attachment is a flat plate, with double sided tape attached, which glues to the fork. if you don't want to get a new computer, you could simply do a ghetto solution: duct tape the sensor to the fork, or glue it, or zip tie it.

Sounds like you are trying to mount the sensor on the inside of the fork blade - if that's the case, move the sensor to either the leading or trailing edge of the fork, and just rotate it around the blade until you get the clearance you need.
Put it in front of the fork.Spoke Wrench

If you mount it in the back, and it ever gets knocked into the wheel, the wheel rotation will cause it to rotate into the spokes and cause serious damage to both you and your bike. Front mounting is much safer.

Yes indeed - sounds like a recipe for a hospital visit. There's got to be a better way!
agree on the front being best, but...DrD

that would have to be one hell of a manly computer sensor to cause you to crash - it's not like it's bolted onto the fork!

The best place for the sensor is on the leading edge of the fork (pretty much have to do that for the shimano wireless flightdeck) - however, if it were on the trailing edge, and it got sucked into the spokes, it would just get ripped off of the fork and flung off the bike... the sensor wire and tie wraps aren't that strong! Also - how is it going to get bumped into the spokes while you are actually riding?

The more I think about it, the more I like the solution someone suggested at the
bicycling maintenance forum. It is this: if you can find a way to mount a sensor
at the rear wheel that would work.

Well, the cables on most cycling computers are way too short and wireless just
isn't in the budget right now.

My wife got a Vetta RT55 for her recumbent. It comes with a very long sensor
lead.

I mount the magnet to one of the spokes on the rear wheel and mount the sensor
to the left chainstay and zip tie the cable up the frame (giving ample clearance
for steering) and do it that way.

I'll be bringing back the Speedzone to the local shop and see what they suggest as
well.

Thanks for the all the suggestions and I'll be posting back on what I do.

The space between a chainstay and rear wheel is much wider than front wheel spacing.

I created a website on how I solved the issue. Thanks everyone for all the suggestions!
