    Riser bar or riser stem?

    This 35 year old Shogun has a very small frame , however using most of the standard seat post and fitting a riser stem ( Suntour copy ) with some riser bars has resulted in a very comfortable riding position which is easily adjusted to suit a smaller rider if required

    What is the maximum tooth sprocket you could fit on the back using a Deore DX rear derailleur?

    Reading through this has cost me 15 minutes of my life that I won't get back ! What a complete waste of time and wind up

    Old BSA bicycle S399

    The simplest way to date this bike is to look at the Sturmey Archer rear hub . You will find the date of manufacture stamped on the body of the hub between the spoke flanges . The bike would have been built slightly after this date but will at least give you some idea . The bike looks to be in...

    Parabike?

    Interesting find , this is certainly an original Parabike and is probably one of many that were sold off at the end of the war to businesses like Gamages in London . They replaced the original sliding pedals with those you see here and fitted mudguards . Being government surplus they were...

    AMP Research fork - what year is this? model number please? thank you :)

    It appears from your comment ' does it have a spring ' etc that the spring and elastomer bump stop are missing You may have a problem as the springs were specially made for AMP ( in three ? body weight/stiffness sizes ) and there do not appear to be any stock springs , metric or imperial , that...

    Seat Post - how to remove marks from slipping?

    Why ? Leave the inserted section alone and polish the rest . Did a similar job on a black anodised Kalloy post the other day , the finish was faded and worn in places . It now looks like new Check out the reason for the original problem , usually the poor finish to the inside of the...

    Bent aluminum hanger. Help please!

    I have used a slight variation to this idea as follows : Fit a spare axle in the place of the existing wheel using heavy duty washers and nuts on both sides of the dropouts , making sure that the OLN measurement is the same as the wheel . Fit another axle into the gear hanger again using...

    Why do we want rare, complicated stuff?! Amp forks kupput

    It appears that you have a pair of AMP F1 forks . These have a single centrally positioned compression spring backed up by an elastomer plug which stops the spring from coil binding at full travel . The F2 version is similar albeit with slightly changed geometry . The F3 and F4 variants have...

    Trying to figure out who made this

    Looks to be a 1980 frame with some Campag bits . Most likely had a respray at some time so makers and tubing decals no longer visible . Could be a Mercian ? probably easier to take a decent photo and list it in the road bike section with its frame number , as its clearly not an MTB

    Saddle comfort - Turbo vs Unicanitor

    Thanks for the link to your new bike which I had not spotted . It looks like a really interesting find , with what looks like all original period correct components in very good condition (except saddle !) The Italian bars may be the best clue to its origins ? Have you checked the date codes on...

    Saddle comfort - Turbo vs Unicanitor

    Looks fine , go for it ! Saying that , I have never heard of a Cinelli Unicanitor Saddle being fitted to a MTB mainly because the revolutionary plastic saddle design existed way before there was such a thing as a MTB and as such its primary market was the road bike in various competitive forms

    Saddle comfort - Turbo vs Unicanitor

    The original Unicanitor moulded plastic saddle was available with different levels of comfort determined by the amount of padding fitted to the shell before the leather outer was fitted . A Unicanitor no.1 had no padding at all , with progressively more padding until you reached no.4 ( I think )...

    Raleigh maverick circa 1985 brake studs & bottom bracket.

    To retain the period look , the original brakes were Dia Compe Cantilevers with external springs I believe them to be Dia Compe 980 GC , though I can't quite reach my own bike to confirm

    Help with removing Yo Eddy ‘91 press fit BB

    No personal experience of this bike but have fitted new press fit ball bearings to Viscount Aerospace B/B in the past Its not worth trying to save the existing bearings , drive them out as suggested above ( the first is the hardest ) and make a note of any part numbers and preferably the size...

    The last Overburys Crossfell to ever leave the shop !

    The Nitto riser bars and stem are a departure from the Nitto bullmoose bars that were originally specified for all three of these Overburys models . However upon reflection I suspect that the limited range of fit options associated with bullmoose bars led to the installation of the more...

    The last Overburys Crossfell to ever leave the shop !

    The view of the top of the rear triangle shows the ESGE mudguard that had been shortened for convenience , to be replaced by an almost identical Bleumels product that I already had , also shortened . The rack still had a ' makers ' label declaring it to be a Nimrod Product , however , based in...

    The last Overburys Crossfell to ever leave the shop !

    When I first saw the bike my initial response was to start again ie. shot blast and re - finish with new decals etc replacing missing items so that it would appear exactly as it left the shop . This remained my intention as I gradually worked through the various components until I just had the...
