Good value, well made chain whip.

On: 2008-09-26

I bought this so that I would be able to repair my 2007 Schwinn Sierra GS with the DPN 13-34 Mega Gear freewheel ... Not a cassette duh ... oh well I have an extra tool for the neighbor kids to borrow.

I know well made tools and this is a nice tool that will last if used occasionally by the shade tree mechanic ... unfortunately I am not yet a good bicycle mechanic and bought this along with the FR-5 cassette lock ring tool for my 13-34 Mega Gear Freewheel not to be confused with the Shimano Mega Range 13-34 freewheel ... the FR-5 does not fit the DPN Mega Gear 13-34 found on many low end bicycles.

I believe the DPN 13-34 requires the Park FR-1 but until I speak to Park Tools I will not say for sure; I called Park Tool this week but their people were out of town at a seminar, I will call next week and find the correct tool for those who have the DPN ... as this freewheel is hidden in layers of companies and if my Asian searches are correct the company uses DNP in their literature not DPN as is stamped on the Schwinn freewheel, yes I am confused.

I tagged this with several key words as I have spent months trying to find the replacement components I may need quickly when something breaks and I know there are many DPN Mega Gear owners that would like to do minor repairs but cannot find information on their bike that uses the 13-34 gear setup.

A good tool if you look at all within this category and compare prices, for the professional I would purchase the heavier chain whip and maybe use this one with the more expensive one when TWO chain whips are required ... frequency of use is the keyword and do not neglect the SIZE of the chain if you have several bikes with WIDE sprockets where this would not hold a wider sprocket.

Chain whip clones and the real thing

This is the genuine article from Park ... I would recommend
using this chain whip, or something high-quality, such as the
TORX ST-501A. Removing a freewheel, simple as it sounds, if not
done yearly, may result in a freewheel that is hard to remove as
removing a tooth from a jaw, for example. Its important to
have a spare chain whip, in case one breaks ... I had a cheap
whip from the PRON toolkit, that just broke. Also, be sure to
have PAINT THINNER / degreaser liquid nearby to clean the cassette,
as well as a CHAIN SCRUBBER such as the TORX ST-790 which really
cleans the inside very well from its semi-circular brush shape.
Also handy, is WD-40, to loosen this up, and a small sledge hammer.
A grease gun is essential, loaded with grease to lube up the inside
of the ball-bearings allowing the wheel to rotate, and the regular
detergent and high pressure water hose to clean potential dirt
accumulated from mult years of neglect. Perhaps an extra cassette would
be good, if you break off any tooth on the cassette during the process
of removing the freewheel.
