No rest for the wicked is there? Not even on a Sunday morning.
It's the same type as the one mentioned in the other thread, another early example from around 1990. Several of these caliper braked models seem to have surfaced over the last few months, Raleigh must have been selling them by the shed load. Loads seem to have survived, quite possibly because of the kind of customer who tended to buy them.
They're no lightweights, but the frames have decent geometry and give a good ride. Steel is plain-gauge 18-23 hi-tensile, which was the standard mass-production frame material used for decades. Perfectly practical for general leisure/utility cycling and could easily be used for touring with a decent rack. I actually had a frame failure on one of these, on the O/S chainstay at the dropout. That's unusual for steel, but the one I built up was very battered and scruffy, so it might have just been a case of a freak bad frame that had also suffered a lot of abuse. You don't tend to hear much about frame failures on steel Pioneers, so I think it's safe to assume mine was the exception to the rule. The versions with steel wheels are heavier and don't stop so well in the wet, so if you have one of these, ride it appropriately and try your brakes in good time, not right at the last minute!
Mechanically, they seem to have been largely based on then-current MTB stuff as they have similar mechs and shifters to Raleigh MTB's of the same era. Given some regular lubrication, these bikes can be kept on the road for peanuts in maintenance costs, which is one of the reasons I like them. They tended to fetch very low prices pre-corona anyway, and don't seem too popular with bike thieves because of this.
If this one has the extra wide handlebars - over 26", they are a real nuisance for traffic riding and getting through barriers on cycle paths, so it's a good move to trim them down to 23" wide, which makes a big difference but still leaves room for the brakes and shifters. Later ones were 24 1/2" wide, which is still more that ideal.
