Chris, Victor and other trikers,
Other than duct tape and zip ties, I have come across four ways to mount lights on the front
derailleur post of a GS-type tadpole
1. The front light mount for a Trice. About $20? Check the ICE website for local dealers.
http://www.ice.hpv.co.uk/
Sturdy and mounts two lights. Involves drilling and tapping holes spaced for a water bottle mount (~
2.5" apart). There is enough room and if you don't need the lights, you've got another place for a
water bottle. Not DYI for me.
2. A T-Bar light mount from Vision or Haluzak (sp?). About $30 Check online for dealers. It is
available at The Hostel Shoppe.

Sturdy and mounts two lights. Involves cutting off the front of the tab on the top of the post with
a hacksaw or Dremel. Then cutting the top of the tube off with a pipe cutter to get an open topped
tube. Could be a DYI project but not for me.
3. The Greenspeed light mount. About $15 Available from Greenspeed dealers.

Sturdy but only mounts one light. Just bolts on. Could be another home project with the right
material. The plastic plumbing pieces I tried didn't hold up well.
4. Buy a Topeak S.P.P. Fixer Model 1a. Price unknown
(S.P.P. Fixer = Seat Post Pack Fixer) Get the model for seats with springs. The metal clamp from the
S.P.Q.F has a larger diameter. A perfect fit around the front post on a GTO. It even uses the same
size bolt as a Space Grip. Swap the clamps and bolt it on.
Not as sturdy as the first three. Involves shortening the tube on the Space Grip to fit between the
cranks. The S.P.P.F may be a little hard to find. Any LBS that deals with JB Importers should be
able to order it. Topeak makes two models. Get the one for seats with springs.
I have pictures of the things mentioned above. Contact me directly rather than on a.r.b.r. See
from above.
If you find any other solutions, please post, Ron and GTO 618
