I agree with goonster, it will not be noticeably wiggly unless your
power output is 300+watts. Looks like a good frame for LD
riding, depending on the price. As to that, a steal would $300-600,
a good buy would be in the $500-800 range, above $800 is, well
optimistic or dreamland, on the part of the seller IMO. Others
may have other opinions.
