The Jump Stop weighs 30 grams. • The clamp is made of fiber-reinforced and UV stabilized DuPont Zytel--easy on your frame finish. • All steel is stainless. • Tool is included. • No-hassle / no-time-limit warranty (if any part fails, I replace it). • Black only.

In most cases, the needed Jump Stop clamp size will be the same as the front derailleur clamp size.  If there is no size stamped on the front derailleur, or there is no front derailleur, the easiest way to determine seat tube diameter is to cut a strip of paper 4 inches (100 mm) in length, and wrap it around the seat tube. If the ends overlap by more than a quarter inch (7mm), it's probably 1-1/8 (29mm). If the ends just barely meet, it's probably 1-1/4 (32mm). If the ends have a gap between them greater than a quarter inch (7mm), it's probably 1-3/8 (35mm). If you have questions about how difficult it is to mount the Jump Stop, the instruction sheet is reproduced here.

There are some independent bike shops which now carry the Jump Stop, but as of yet, there are still many which don't.  If your preferred shop doesn't carry it, or for people who don't have a shop close by, the Jump Stop may be ordered direct.

You can order by e-mailing me at ngear@gvtc.com or by calling (800) 659-4607 (toll free) or (830) 755-4607 (local or toll).  I will need to know what size you need and the destination postal address.  I don't require pre-payment, so if you would like to confirm that the Jump Stop is the right guide for your bike, you are welcome to try it out first to make sure it fits and does what you want. Then you can decide whether or not to keep it.  (If not, just mail the parts back.)

If you decide to buy, I accept cash, check, money order, and Paypal (to ngear@gvtc.com).  The following charges would apply.  (Text revised 6/3/08 to try to remove some ambiguity in the way the prices were previously stated.)

2 units           $20

If costs continue to rise at the present rate, I will probably have to bump the price again later this year.  In that event, I will try to give at least two weeks advance notice here.

If you have any questions, feel free to e-mail or call.  (If you call my 800 number, it would help me to contain costs if I could call you back.)  Thank you for taking the time to read about the Jump Stop.
